ASP.NET Interview Questions This is a list of questions I have gathered and created over a period of time from my experience, many of which I felt where incomplete or simply wrong. I have finally taken the time to go through each question and correct them to the best of my ability. However, please feel free to post feedback to challenge, improve, or suggest new questions. I want to thank those of you that have contributed quality questions and corrections thus far. There are some questions in this list that I do not consider to be good questions for an interview. However, they do exist on other lists available on the Internet so I felt compelled to keep them here for easy access.

1.

Describe the role of inetinfo.exe, aspnet_isapi.dll andaspnet_wp.exe in the page loading process. inetinfo.exe is theMicrosoft IIS server running, handling ASP.NET requests among other things.When an ASP.NET request is received (usually a file with .aspx extension), the ISAPI filter aspnet_isapi.dll takes care of it by passing the request tothe actual worker process aspnet_wp.exe.

2.

What’s the difference between Response.Write() andResponse.Output.Write()? Response.Output.Write() allows you to write formatted output.

3.

What methods are fired during the page load? Init() - when the page is instantiated Load() - when the page is loaded into server memory PreRender() - the brief moment before the page is displayed to the user as HTML Unload() - when page finishes loading.

4.

When during the page processing cycle is ViewState available? After the Init() and before the Page_Load(), or OnLoad() for a control.

5.

What namespace does the Web page belong in the .NET Framework class hierarchy? System.Web.UI.Page

6.

Where do you store the information about the user’s locale? System.Web.UI.Page.Culture

7.

What’s the difference between Codebehind="MyCode.aspx.cs" andSrc="MyCode.aspx.cs"? CodeBehind is relevant to Visual Studio.NET only.

8.

What’s a bubbled event? When you have a complex control, like DataGrid, writing an event processing routine for each object (cell, button, row, etc.) is quite tedious. The controls can bubble up their eventhandlers, allowing the main DataGrid event handler to take care of its constituents.

9.

Suppose you want a certain ASP.NET function executed on MouseOver for a certain button. Where do you add an event handler? Add an OnMouseOver attribute to the button. Example: btnSubmit.Attributes.Add("onmouseover","someClientCodeHere();");

10. What data types do the RangeValidator control support? Integer, String, and Date.

11. Explain the differences between Server-side and Client-side code? Server-side code executes on the server. Client-side code executes in the client's browser.

12. What type of code (server or client) is found in a Code-Behind class?

The answer is server-side code since code-behind is executed on the server. However, during the code-behind's execution on the server, it can render client-side code such as JavaScript to be processed in the clients browser. But just to be clear, code-behind executes on the server, thus making it server-side code.

13. Should user input data validation occur server-side or client-side?

Why? All user input data validation should occur on the server at a minimum. Additionally, client-side validation can be performed where deemed appropriate and feasable to provide a richer, more responsive experience for the user.

14. What is the difference between Server.Transfer and Response.Redirect?

Why would I choose one over the other? Server.Transfer transfers page processing from one page directly to the next page without making a round-trip back to the client's browser. This provides a faster response with a little less overhead on the server. Server.Transfer does not update the clients url history list or current url. Response.Redirect is used to redirect the user's browser to another page or site. This performas a trip back to the client where the client's browser is redirected to the new page. The user's browser history list is updated to reflect the new address.

15. Can you explain the difference between an ADO.NET Dataset and an ADO

Recordset? Valid answers are: · A DataSet can represent an entire relational database in memory, complete with tables, relations, and views. · A DataSet is designed to work without any continuing connection to the original data source. · Data in a DataSet is bulk-loaded, rather than being loaded on demand. · There's no concept of cursor types in a DataSet. · DataSets have no current record pointer You can use For Each loops to move through the data. · You can store many edits in a DataSet, and write them to the original data source in a single operation. · Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources.

16. What is the Global.asax used for? The Global.asax (including the Global.asax.cs file) is used to implement application and session level events.

17. What are the Application_Start and Session_Start subroutines used for? This is where you can set the specific variables for the Application and Session objects.

18. Can you explain what inheritance is and an example of when you might use it? When you want to inherit (use the functionality of) another class. Example: With a base class named Employee, a Manager class could be derived from the Employee

base class.

19. Whats an assembly? Assemblies are the building blocks of the .NET framework. Overview of assemblies from MSDN

20. Describe the difference between inline and code behind.

Inline code written along side the html in a page. Code-behind is code written in a separate file and referenced by the .aspx page.

21. Explain what a diffgram is, and a good use for one? The DiffGram is one of the two XML formats that you can use to render DataSet object contents to XML. A good use is reading database data to an XML file to be sent to a Web Service.

22. Whats MSIL, and why should my developers need an appreciation of it if at all? MSIL is the Microsoft Intermediate Language. All .NET compatible languages will get converted to MSIL. MSIL also allows the .NET Framework to JIT compile the assembly on the installed computer.

23. Which method do you invoke on the DataAdapter control to load your generated dataset with data? The Fill() method.

24. Can you edit data in the Repeater control? No, it just reads the information from its data source.

25. Which template must you provide, in order to display data in a Repeater control? ItemTemplate.

26. How can you provide an alternating color scheme in a Repeater control? Use the AlternatingItemTemplate.

27. What property must you set, and what method must you call in your code, in order to bind the data from a data source to the Repeater control? You must set the DataSource property and call the DataBind method.

28. What base class do all Web Forms inherit from? The Page class.

29. Name two properties common in every validation control? ControlToValidate property and Text property.

30. Which property on a Combo Box do you set with a column name, prior to setting the DataSource, to display data in the combo box? DataTextField property.

31. Which control would you use if you needed to make sure the values in two different controls matched? CompareValidator control.

32. How many classes can a single .NET DLL contain? It can contain many classes.

Web Service Questions 1.

What is the transport protocol you use to call a Web service? SOAP (Simple Object Access Protocol) is the preferred protocol.

2.

True or False: A Web service can only be written in .NET? False

3.

What does WSDL stand for? Web Services Description Language.

4.

Where on the Internet would you look for Web services? http://www.uddi.org

5.

True or False: To test a Web service you must create a Windows application or Web application to consume this service? False, the web service comes with a test page and it provides HTTP-GET method to test.

State Management Questions 1.

What is ViewState? ViewState allows the state of objects (serializable) to be stored in a hidden field on the page. ViewState is transported to the client and back to the server, and is not stored on the server or any other external source. ViewState is used the retain the state of server-side objects between postabacks.

2.

What is the lifespan for items stored in ViewState? Item stored in ViewState exist for the life of the current page. This includes postbacks (to the same page).

3.

What does the "EnableViewState" property do? Why would I want it on or off? It allows the page to save the users input on a form across postbacks. It saves the server-side values for a given control into ViewState, which is stored as a hidden value on the page before sending the page to the clients browser. When the page is posted back to the server the server control is recreated with the state stored in viewstate.

4.

What are the different types of Session state management options available with ASP.NET? ASP.NET provides In-Process and Out-of-Process state management. In-Process stores the session in memory on the web server. This requires the a "sticky-server" (or no load-balancing) so that the user is always reconnected to the same web server. Out-of-Process Session state management stores data in an external data source. The external data source may be either a SQL Server or a State Server service. Out-ofProcess state management requires that all objects stored in session are serializable. posted on Tuesday, March 16, 2004 8:14 AM

11. What type of code (server or client) is found in a Code-Behind class? Server-side code. we can write client side code in code-behind calss like button1.Attributes.Add("onMouseOver", "window.open('webform1.aspx')") pls help me

# re: Interview Questions: ASP.NET 7/1/2004 12:44 PM Mark Wagner

You are correct. You can write dynamically created client-side code in the code-behind class just as you have shown in your example. I understand your question and believe you have a good point. However, I would argue the code-behind class should still be considered "serverside" code since that is where it is executing. Client-side code does not execute in the codebehind, it is simply text or data, not really code and is treated as such in the code-behind. Your (excellent) example demonstrates the power of ASP in that a developer can dynamically create HTML, XML, or even Javascript in the code-behind. As you have pointed out, this dynamically generated code would execute on the client-side. In short, you are correct in your assessment and appear to be able to intelligently answer this question should you encounter it in an interview. Great question!

# re: Interview Questions: ASP.NET 7/3/2004 10:36 AM Yasser Hi, This is in response to Question 12, validation should occur on client side and server side both. Client side should happen to avoid server round trip, but it's easily possible to by-pass client side validation. Say if someone has turned of javascript in her browser or if the browser is not supporting javascript? In that scenario client side validation will not work. Hence if the validation is also done on server than such scenario can be avoided. The rule is whether validation occurs on client or not, but it should always occur on server.

# re: Interview Questions: ASP.NET 7/20/2004 3:02 AM Rohit Kalia

This is in response to Question 14 : What is the difference between Server.Transfer and Response.Redirect? Why would I choose one over the other? server.transfer simply transfer execution to another page. this doesn't require any information to be sent to the browser== it all occurs on the server without the user's knowledge. The response.redirect method sends http information to the browser instructing it to go to another page. [email protected]

# re: Interview Questions: ASP.NET 8/8/2004 11:04 PM Fahad Khalil Hi About question 12... the validation on client side. Yes, one should perform the validation on client side... but as they say, *never trust your client, specially thin*. So always perform validation on client side, try to save atleast one trip. If client is not messing

with the HTML, then he is doing a favor on himself. If he is messing, let him waste his own band width. To check whether all the validors on a page validate into *true*, before performing business, you better should do... Page.IsValid or if you want to perform validation for a particular validator, just do... FieldValidator.IsValid. Hope this helps :) mEEEEEEEEEEEEEEE!!!!!!!

# re: Interview Questions: ASP.NET 8/18/2004 9:36 AM Sergey Most questions are good, but asking about property names or tag names has no benefit whatsoever. Why would I memorize them if I have intellisence and MSDN library? Rather concentrate on questions about general programming knowledge and understanding of ASP.NET concepts such as request/response, processing pipelines and code-behind.

# re: Interview Questions: ASP.NET 9/17/2004 10:20 AM Niveditha Hi

The questions and answers in this article are quite useful in an interview. But i am not satisfied by the answer to Q No.14. What is the difference between Server.Transfer and Response.Redirect? Why would I choose one over the other? My answer will be The Response .Redirect () method can be used to redirect the browser to specified url, pointing to any resource and may contain query strings and causes an extra roundtrip Server.Transfer() performs server side redirection of the page avoiding extra roundtrip. Server.Transfer() is preferred over Response.Redirect to avoid rountrip but the limitation is the aspx page should reside on same web server.

# re: Interview Questions: ASP.NET 10/21/2004 11:36 PM Horatiu Cristea Sergey, you know there is a point in asking about proprety names and tag names :) knowing those answers, could prove the interviewed person that he has worked with that stuff, not just theoreticaly knowledge. For example what is the difference between visibility and display styles for a html tag? but what iritates me at intervies and tests is that there are companies that give you as test a small project to do. This has no relevance in my point of view. instead i prefer to test the coding skill on paper. i usualy ask the person to write me on paper a snippet of code of 5-10 lines of code.

# re: Interview Questions: ASP.NET 11/22/2004 10:48 PM Senthilkumar Thirukkami Hi,

Questions listed in the articles sounds good. I am adding more to the above mentioned list. As many opted for some basics in .NET. 1) What is CLS (Common Language Specificaiton)? It provides the set of specificaiton which has to be adhered by any new language writer / Compiler writer for .NET Framework. This ensures Interoperability. For example: Within a ASP.NET application written in C#.NET language, we can refer to any DLL written in any other language supported by .NET Framework. As of now .NET Supports around 32 languages. 2) What is CTS (Common Type System)? It defines about how Objects should be declard, defined and used within .NET. CLS is the subset of CTS. 3) What is Boxing and UnBoxing? Boxing is implicit conversion of ValueTypes to Reference Types (Object) . UnBoxing is explicit conversion of Reference Types (Object) to its equivalent ValueTypes. It requires type-casting. 4) What is the difference between Value Types and Reference Types? Value Types uses Stack to store the data where as the later uses the Heap to store the data. 5) What are the different types of assemblies available and their purpose? Private, Public/shared and Satellite Assemblies. Private Assemblies : Assembly used within an application is known as private assemblies Public/shared Assemblies : Assembly which can be shared across applicaiton is known as shared assemblies. Strong Name has to be created to create a shared assembly. This can be done using SN.EXE. The same has to be registered using GACUtil.exe (Global Assembly Cache). Satellite Assemblies : These assemblies contain resource files pertaining to a locale (Culture+Language). These assemblies are used in deploying an Gloabl applicaiton for different languages. 6) Is String is Value Type or Reference Type in C#? String is an object (Reference Type).

More to come.... Thanks & Regards, Senthilkumar.Thirukkami [email protected]

# re: Interview Questions: ASP.NET 12/5/2004 4:47 AM Niks Good set of questions.

I feel the difference between "src" and "code behind" tag can be better explained from the deployment perspective. When "code behind" tag is used, ASP.NET expects the precompiled dll on the server. When "src" tag is used the code behind is converted to MSIL just in time. Then it does not expect the pre-compiled DLL. So directly the .cs (if C# is used) can be deployed on the server. For further details Microsift msdn help - Knowledge base can be looked.

visit this link again and copy the entire contents into a document.

# re: Interview Questions: ASP.NET 5/4/2005 11:12 AM dan When designing an ASCX control is it good practice to use read from the viewstate in onload event of the control? Why or Why not. answer: Its not good practice because if the control is loaded in page_load by use of LoadControl() it will not see any of its own viewstate in onload. So if there is a textbox on the ascx that the control needs it will not be able to see the postback data. onload { string temp = textbox1.text } temp = "" At the end of the onload event it will sync back up with viewstate. So in any of the userfired events it will have the correct values. Also anything that is not named or loaded global must be loaded before it will respond to events on the pages round trip. If the control is named in the html portion it will have its viewstate synced already in pageload.

# re: Interview Questions: ASP.NET 8/30/2005 5:22 AM Mark Hoffman Some good questions, but many of them are just sheer trivia. These types of questions don't give you any insight in to the person's skill or their ability to think. For example: "What data types do the RangeValidator control support? Integer, String, and Date. " Suppose I know the answer. What does that really tell you? That I've worked with a Range Validator before. Whoopee. Who cares? If I don't now answer then it means that either I don't know it exists, haven't worked with it, or more likely, simply don't remember which data types it supports. I can Google the question

and get a satisfactory answer in about 10 seconds. When I interview, I want to know that the candidate understands deeper concepts than what can be Googled in 30 seconds. Explain to me some particular OOP concepts. When would you use a Singleton? Why? Why use an Interface? How would you implement exception handling in this case? I want to know that they can THINK. Sure, I'll ask some basic questions that are trivial during a phone screening, but asking what namespace some class out of the BCL belongs to is just...well, stupid. It might make you feel superior if you know the answer, but it does nothing to help you find talented programmers who can think intelligently.

# Some ASP.NET questions 9/28/2005 3:51 AM Naren

1. Explain the differences between Server-side and Client-side code? Server side code basically gets executed on the server (for example on a webserver) per request/call basis, while client side code gets executed and rendered on the client side (for example web browser as a platform) per response basis. 2. What type of code (server or client) is found in a Code-Behind class?

In the Code-behind class the server side code resides, and it generates the responses to the client appropriately while it gets called or requested. 3. Should validation (did the user enter a real date) occur server-side or client-side? Why? That depends. In the up browsers (like IE 5.0 and up and Netscape 6.0) this would help if it gets validated on the client side, because it reduces number of round trips between client and server. But for the down level browsers (IE 4.0 and below and Netscape 5.0 and below) it has to be on server side. Reason being the validation code requires some scripting on client side. 4. What does the "EnableViewState" property do? Why would I want it on or off? EnableViewState stores the current state of the page and the objects in it like text boxes, buttons, tables etc. So this helps not losing the state between the round trips between client and server. But this is a very expensive on browser. It delays rendering on the browser, so you should enable it only for the important fields/objects 5. What is the difference between Server.Transfer and Response.Redirect? Why would I choose one over the other? Server.Transfer transfers the currnet context of the page to the next page and also avoids double roundtrips. Where as Response.Redirect could only pass querystring and also requires roundtrip. 6. Can you give an example of when it would be appropriate to use a web service as opposed to a non-serviced .NET component Webservice is one of main component in Service Oriented Architecture. You could use webservices when your clients and servers are running on different networks and also different platforms. This provides a loosely coupled system. And also if the client is behind the firewall it would be easy to use webserivce since it runs on port 80 (by default) instead of having some thing else in SOA apps . 7. Let's say I have an existing application written using Visual Studio 6 (VB 6, InterDev 6) and this application utilizes Windows 2000 COM+ transaction services. How would you approach migrating this application to .NET You have to use System.EnterpriseServices namespace and also COMInterop the existing application 8. Can you explain the difference between an ADO.NET Dataset and an ADO Recordset? ADO.NET DataSet is a mini RDBMS based on XML, where as RecordSet is collection of rows. DataSet is independent of connection and communicates to the database through DataAdapter, so it could be attached to any well defined collections like hashtable, dictionary, tables, arraylists etc. practically. And also it can be bound to DataGrid etc. controls straightaway. RecordSet on the otherhand is tightly coupled to Database System. 9. Can you give an example of what might be best suited to place in the Application_Start and Session_Start subroutines? In the Application_Start event you could store the data, which is used throughout the life time of an application for example application name, where as Session_Start could be used to store the information, which is required for that session of the application say for example user id or user name. 10. If I'm developing an application that must accomodate multiple security levels though secure login and my ASP.NET web appplication is spanned across three web-servers (using round-robbin load balancing) what would be the best approach to maintain login-in state for the users? Use the state server or store the state in the database. This can be easily done through simple setting change in the web.config.

<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="30" /> in the above one instead of mode="InProc", you specifiy stateserver or sqlserver. 11. What are ASP.NET Web Forms? How is this technology different than what is available though ASP (1.0-3.0)? ASP.NET webforms are analogous to Windows Forms which are available to most VB developers. A webform is essentially a core container in a Page. An empty webform is nothing but a HTML Form tag(control) running at server and posting form to itself by default, but you could change it to post it to something else. This is a container, and you could place the web controls, user controls and HTML Controls in that one and interact with user on a postback basis. 12. How does VB.NET/C# achieve polymorphism? Polymorphism is achieved through virtual, overloaded, overridden methods in C# and VB.NET 11. Can you explain what inheritance is and an example of when you might use it? . 13. How would you implement inheYou missed the number sequence here). Inheritance is extending the properites, behaviour, methods to child classes from super classes. VB.NET and C# provide single inheritance, means the subclasses can be derived from only one parent unlike C++, where true multiple inheritance is possible. As an alternate to implement multiple inheritance, we could do the same to implement interfaces to the parent classes and implement the same interfaces to derive the child classesritance using VB.NET/C#? 14. Whats an assembly An assembly is the primary building block of .NET. It's a reusable, self-describing, versionable deployment unit for types and resources. They are self-describing so to allow the .NET runtime to fully understand the application and enforce dependency and versioning rules 15. Describe the difference between inline and code behind - which is best in a 16. loosely coupled solution 5 and 16. (You missed the sequence again). Inline style is mixing the server side code and client side code (HTML and javascript) on the same page and run it. Where as codebehind is seperating the server side in a different page (enabling developers/coders to work) and leaving the client side code to do the presentation only (so designers would work on it). Inline code would be simplest way of approach because it doesn't require any pre-compilation. But it is not good in many ways, i. You mix the presentation and server side code together so whenever there is a change it would be tough to maintain. ii. The event processing would be a night mare in inline code. iii. Since the codebehind needs to be compile in advance, it would be faster unline inline, which is interpreted per call basis. In a loosely couple situation, codebehind would be the best way to approach. Because it provides better performance. 17. Explain what a diffgram is, and a good use for one http://msdn.microsoft.com/library/default.asp?url=/library/enus/sqlxml3/htm/dotnet_11pr.asp 18. Where would you use an iHTTPModule, and what are the limitations of any 19. approach you might take in implementing one 20. What are the disadvantages of viewstate/what are the benefits 21 Describe session handling in a webfarm, how does it work and what are the > limits

22. How would you get ASP.NET running in Apache web servers - why would you even do this? 23. Whats MSIL, and why should my developers need an appreciation of it if at all? 24. In what order do the events of an ASPX page execute. As a developer is it important to undertsand these events? 25. Which method do you invoke on the DataAdapter control to load your generated dataset with data? 26. Can you edit data in the Repeater control? 27. Which template must you provide, in order to display data in a Repeater control? 28. How can you provide an alternating color scheme in a Repeater control? 29. What property must you set, and what method must you call in your code, in order to bind the data from some data source to the Repeater control? 30. What base class do all Web Forms inherit from? 31. What method do you use to explicitly kill a user s session? 32 How do you turn off cookies for one page in your site? 33. Which two properties are on every validation control? 34. What tags do you need to add within the asp:datagrid tags to bind columns manually? 35. How do you create a permanent cookie? Supply never to the expiration date/time 36. What tag do you use to add a hyperlink column to the DataGrid? 37. What is the standard you use to wrap up a call to a Web service 38. Which method do you use to redirect the user to another page without performing a round trip to the client? 39. What is the transport protocol you use to call a Web service SOAP 40. True or False: A Web service can only be written in .NET 41. What does WSDL stand for? 42. What property do you have to set to tell the grid which page to go to when using the Pager object? 43. Where on the Internet would you look for Web services? 44. What tags do you need to add within the asp:datagrid tags to bind columns manually. 45. Which property on a Combo Box do you set with a column name, prior to setting the DataSource, to display data in the combo box? 46. How is a property designated as read-only? 47. Which control would you use if you needed to make sure the values in two different controls matched? 48. True or False: To test a Web service you must create a windows application or Web application to consume this service? 49. How many classes can a single .NET DLL contain? 1 Describe session handling in a webform, how does it work and what are the its limits Sometimes it is necessary to carry a particular session data across pages. And HTTP is a stateless protocol. In order to maintain state between page calls, we could use cookies, hidden form fields etc. One of them is using sessions. each sessions are maintain a unique key on the server and serialize the data on it. Actually it is a hashtable and stores data on key/value pair of combination. You could set a session using Session Object and retrieve the same data/state by passing the key. //Set Session["abc"] = "Session Value"; // Get string abc = Session["abc"].ToString(); The downside of sessions is scalability. Say your application gets more and more hits

and you though instead of one webserver handling it, have it in a webfarm (multiple web servers working under one domain). You cannot transfer the session so easily across multiple webservers. Reason is like I said, it physically serializes the state data to webserver hard disk. .NET proposes a new way to handle this using a stateserver (actually a trimmed down sql server) storing the web session data in a factory configured database schema or using Database with your own schema defined to handle the sessions. 2. How would you get ASP.NET running in Apache web servers - why would you even do this? You need to create a CLRHost, which hosts the CLR (ASP.NET) on top of Apache. Since Apache is #1 webserver used by many companies, this would allow more number of web site owners to take advantage of ASP.NET and its richness. 3. Whats MSIL, and why should my developers need an appreciation of it if at all? MSIL is Microsoft Intermediate (Intermediary) Language. It is Microsoft's implementation of CIL (standard recognized by ECMA and ISO) as part of CLI and C# Standardization. .NET supports more than 21 language (I think 24 now). They compile to IL first and then this IL would get JITted to Native code at runtime. Learning IL is advantageous in many terms. The important one is sometimes you need to optimize your code, so you could disassemble your compile assembly using ILDASM and tweak your code and re assemble it using ILASM. 4. In what order do the events of an ASPX page execute. As a developer is it important to undertsand these events? This is the order of Page events i. Page_Init ii.Page_LoadViewState iii. Page_LoadPostData iv. Page_Load v. Page_RaisePostDataChanged vi. Page_RaisePostBackEvent vii. Page_PreRender viii. Page_SaveViewState ix. Page_Render x. Page_Dispose xii. Page_Error (this is caused whenever there is an exception at the page level). Out of all the Page_Load is the one where your code gets loaded and your magic should be written. page_init occurs only once, i.e. when the page is initially created. As a developer you need to know these, becuase your development activity is coding for these only. 5. Which method do you invoke on the DataAdapter control to load your generated dataset with data?

Fill() 6. Can you edit data in the Repeater control? No. Only DataList and DataGrid provide you editing capabilities. 7. Which template must you provide, in order to display data in a Repeater control? ItemTemplate 8. How can you provide an alternating color scheme in a Repeater control? Use AlternatingItemTemplate 9. What property must you set, and what method must you call in your code, in order to bind the data from some data source to the Repeater control? The text property and the DataBind Method. 10. What base class do all Web Forms inherit from? System.Web.UI.Page 11. What method do you use to explicitly kill a user s session? Session.Abandon 12 How do you turn off cookies for one page in your site? Actually I never did this. But there should be a way to do this. May be need to write your own code to do this using Response.Cookies collection and HTTPCookie class and also SessionStateMode. Or there may be some simple way to do it. Need to do further research on this. 13. Which two properties are on every validation control? The common properties are: i. IsValid (bool) ii. ControlToValidate (string) iii. ErrorMessage (string) iv. ValidationDisplay (Display) v. Text (string) The common method is: Validate() 14. What tags do you need to add within the asp:datagrid tags to bind columns manually? You need to set AutoGenerateColumns Property to false. 15. How do you create a permanent cookie? If you are developing web services and the cookies need to be travelled across multiple requests, then you need to have permanent or persistant cookie. In order to do this, you have to set the your webserivce CookieContainer to a newly created CookieContainer, and the

its cookie to a session value and then store the cookie(s) into the Service CookieCollection from that cookie container if something is there othere wise add cookie to the container. 16. What tag do you use to add a hyperlink column to the DataGrid? HyperLinkColumn 17. What is the standard you use to wrap up a call to a Web service SOAP. 18. Which method do you use to redirect the user to another page without performing a round trip to the client? Server.Transfer Response.Redirect also does that but it requires round trip between client and server. 19. What is the transport protocol you use to call a Web service SOAP SOAP 20. True or False: A Web service can only be written in .NET False. 21. What does WSDL stand for? Web Services Description Language. 22. What property do you have to set to tell the grid which page to go to when using the Pager object? CurrentPageIndex. You need to set this one with the DataGridPageChangedEventArgs' NewPageIndex. 23. Where on the Internet would you look for Web services? UDDI.org, UDDI.Org (even microsoft maintains a uddi server-- http://uddi.microsoft.com) UDDI is Universal Description, Discovery and Integration of Web Services. The UDDI servers serves as yellow pages to WebServices (visit http://www.uddi.org) 24. What tags do you need to add within the asp:datagrid tags to bind columns manually. Set AutoGenerateColumns Property to false on the datagrid tag 25. Which property on a Combo Box do you set with a column name, prior to setting the DataSource, to display data in the combo box? ListItem. 26. How is a property designated as read-only? If it has only get accessor. ex: public class abc { private string stringIt="This is the string"; public string StringIt { get { return stringIt; } } } But you could set an attribute prior to the property name with [ReadOnly="true"], if that property defined an attribute

27. Which control would you use if you needed to make sure the values in two different controls matched? Use CompareValidator 28. True or False: To test a Web service you must create a windows application or Web application to consume this service? False. The webservice comes with a test page and it provides HTTP-GET method to test. And if the web service turned off HTTP-GET for security purposes then you need to create a web application or windows app as a client to this to test. 29. How many classes can a single .NET DLL contain? many is correct. Yes an assembly can contain one or more classes and an assembly can be contained in one dll or could spread across multiple dlls. too. Take System.dll, it is collections of so many classes. 2. What is CLR ? 2.1. Diff between CLR & CTS 3. Trace and Debug belongs to which namespaces? 4. ColumnMapping belongs to which namespaces? 5. In order to get assembly info whcih namespace we should import? 6. DIff. between Friend and Protected Friend. 7. What is an abstract class? 8. What is diff. between abstract class and an interface? · what is shadowing ? · Overloading allows a subclass to add a new variation of a method. As long as the new variation has a different method signature, it can have the same name as an existing method on the base class. Shadowing, on the other hand, entirely replaces all variations of the method from the base class, leaving the subclass with only a single version of the method—the one we created through shadowing. Shadowing does not extend an interface, but rather replaces existing methods. Overriding allows a subclass to alter or replace an existing method with the permission of the base class designer. Shadowing can be done without the permission of the base class designer, which is a risky proposition and one that requires extensive testing because the base class was never designed with such a thing in mind. Also, as we discussed earlier, overriding uses virtual methods so the implementation of the method that is invoked is based on the data type of the underlying object, not the data type of the variable we're using. When a method is shadowed it is not virtual, and it is the data type of the variable that dictates the implementation of the method that will be used. The data type of the underlying object is ignored. http://msdn.microsoft.com/library/default.asp?url=/library/enus/dnadvnet/html/vbnet12252001.asp · * diff between Overriding and overloading 9.

How do we Sort the data from a Dataset? 24. how do we get only edited/deleted/inserted records from a Dataset? 25. how Dataadapter.fill works? 26. how can we implement a Identity (SQL Server) call in an asp.net page? 27. What is Viewstate? 28. What is the life cycle of an asp.net page? 1. What does the keyword static mean when applied to a class member? 1. It means the method can be called through the class without instantiating the class. 2. Declare a method called calculate that takes one integer, adds one and returns the result. Allow this method to be overridden by an inheriting class. 2. Public virtual int calculate(int value) { newValue = value + 1; return newValue; } value++; return value; 3. What is the difference between a class and a struct? 3. The class object is stored in the heap and struct object is stored in the stack. Therefore accessing and removing data from the struct is faster than for a class. 4. What is the difference between a class and an interface? 4. You can instantiate a class but you cannot instantiate an interace you can only offer the functionality of that interface. 5. What are the .Net web authentication options and which one would generally be used for a secured/public site? 5. None Windows Authentication –Secured side IIS Authentication Forms Authentication – Public Side 6. What are some .Net options for maintaining session state? 6. In process and out of process. (wasn't sure about this one?) I believe the 6th one could be Querystring, Cookies, Session objects (variables) I wasn't sure, but I knew they could either be handled in the memory on the local machine (in process) or through the ASP.NET state service running either locally or remotely (out of process). 7. What is a Singleton? 7. This ensures that a class can only be instantiated once. Using the EMPLOYEE and JOBS tables, fill in the following stored procedure template so that it removes a job by job_id and all associated employees ensuring that both updates succeed or fail together. CREATE PROCEDURE deleteJob @jobid smallint AS

Database Answer: CREATE PROCEDURE deleteJob @jobid smallint AS BEGIN BEGIN TRAN IF EXISTS (SELECT * FROM JOBS WHERE job_id = @jobid) DELETE FROM JOBS WHERE job_id = @jobid IF @@ERROR <> 0 BEGIN RAISERROR(‘Could not delete row from Jobs – Abort’, 16,1) GOTO Errorhandler END IF EXISTS(SELECT * FROM EMPLOYEES WHERE job_id = @jobid) DELETE FROM EMPLOYEES WHERE job_id = @jobid IF @@ ERROR <> 0 BEGIN RAISERROR(‘Could not delete row from Employees – Abort’, 16,1) GOTO Errorhandler END COMMIT RETURN Errorhandler: ROLLBACK TRAN RETURN END You could also ask him what situations to use a datareader in, when to use a dataset etc... for ado.net In general they will be questions bascially on the SQL Server management, what kind of different services it provides. what the replication methods used. They will give you a situation where you have to choose which type of SQL sever edition you have to use. (there are 7). About ADO.NET, they will give some senario and ask you to use the appropriate methods like sort,filter, row state enumeration and all

1. What is other name for shared assembly? 2. How do you create and use shared assemblies? 3. How do you use thread in your .NET application? 4. what are the main differences between Web Server controls and HTML Server controls? 5. Differences between ref and out parameters? 6. How will you consume web services in ASP.NET? 7. To test web service you must create a windows application or web application to consume this service (True or False). 8. When on the internet would you look for web services? 9. Does .NET supports Pessimistic record locking or Optimistic record locking or both? 10. What is Catch API? 11. How do you handle concurrency errors? 12. where on the internet would you look for web services? 13. In .NET Exception handling model, what are the benefits of over return code? · Shared assemblies. By including a strong name, the assembly can be shared by multiple applications running on the same machine when installed in the Global Assembly Cache (GAC).

This code-sharing model is the inverse of the model used in the unmanaged world, where COM components are automatically shared when compiled and registered in the system registry. Serviced Components. For a .NET class to take advantage of Enterprise Services (COM+ Services), such as distributed transactions and object pooling, the assembly that contains the class—called a Serviced Component because it inherits from the class EnterpriseServices.ServicedComponent—must have a strong name. Having a strong name allows Enterprise Services to be sure it loads the correct assembly. Serviced Components that run in the process hosted by Enterprise Services (DLLHost.exe) should be placed in the GAC, while those running as library applications in the caller's process need not ADO.NET and Visual Studio .NET use optimistic concurrency, because the data architecture is based on disconnected data. Therefore, you need to add business logic to resolve issues with optimistic concurrency. If you choose to use optimistic concurrency, there are two general ways to determine if changes have occurred: the version approach (true version numbers or date-time stamps) and the saving all values approach. · be. sion Number ApproachIn the version number approach, the record to be updated must have a column that contains a date-time stamp or version number. The date-time stamp or a version number is saved on the client when the record is read. This value is then made part of the update.One way to handle concurrency is to update only if value in the WHERE clause matches the value on the record. The SQL representation of this approach is: UPDATE Table1 SET Column1 = @newvalue1, Column2 = @newvalue2 WHERE DateTimeStamp = @origDateTimeStamp Alternatively, the comparison can be made using the version number: UPDATE Table1 SET Column1 = @newvalue1, Column2 = @newvalue2 WHERE RowVersion = @origRowVersionValue If the date-time stamps or version numbers match, the record in the data store has not changed and can be safely updated with the new values from the dataset. An error is returned if they don't match. You can write code to implement this form of concurrency checking in Visual Studio .NET. You will also have to write code to respond to any update conflicts. To keep the date-time stamp or version number accurate, you need to set up a trigger on the table to update it when a change to a row occurs A finally block can not have with break; continue; return or goto statements Hi Friends, I know some of the answers.... but i want to recheck it...

CLR - The common language runtime is the execution engine for .NET Framework applications. It provides a number of services, including the following: Code management (loading and execution) Application memory isolation Verification of type safety Conversion of IL to native code Access to metadata (enhanced type information) Managing memory for managed objects Enforcement of code access security Exception handling, including cross-language exceptions Interoperation between managed code, COM objects, and pre-existing DLLs (unmanaged code and data)

Automation of object layout Support for developer services (profiling, debugging, and so on) CTS - The common type system is a rich type system, built into the common language runtime, that supports the types and operations found in most programming languages. The common type system supports the complete implementation of a wide range of programming languages. 3. System.Diagnostics 4. System.Data.Common 5. System.Reflection 6. Protected - Available only to classes that inherit from our class. Friend - Available only to code within the project/component. Protected Friend - Available only to classes that inherit from our class (in any project) or to code within our project/component. This is a combination of Protected and Friend. 7. Abstract classes cannot be instantiated they can only be extended. You call the functionality of the abstract class without having to create an instance of it. 8. a) Interfaces don't have implementation and abstract classes can be partially implemented. From a practical point of view, interfaces can be implemented in any class and more than one interface can be implemented in a class, but abstract classes can only be implemented in the same class hierarchy (subclassing) and only one abstract class can be implemented in a class. b) Basically it's an mixture of non-virtual methods and method hiding. That is, in VB.NET overriding methods never hide while non-overriding methods always do. c) Overloading a method means that you are providing another version of an existing method that takes different input arguments/parameters. The method will have the same name as an existing method and may or may not have a different return type. It must have a different number and/or type of input parameters. Methods are identified by their name, and number and type of arguments. This is known as the method's signature. The return value of a method is not regarded as part of the signature. Overloading can be done within the same class i.e. you can have several methods defined in one class that have the same name, but different arguments, or it can be done in a class related to another by inheritance i.e. the superclass contains one method, and a subclass provides another version of the method with the same name and different arguments. Overriding a method means that you are replacing the method with your own version. The overriding method must be defined identically to the method being replaced. Overriding can only be done in inherited classes i.e. the superclass provides a method and the subclass redefines the method with one that has exactly the same name and arguments as the superclass version. This will cause the method to behave differently when it is called by an object of the subclass, to when it is called by an object of the superclass. 9. Has application scope...variable only goes out of scope when the application ends. code: public static int Size = 0;

10. The datareader is a forward only, readonly object. It will keep a connection open as long as it is open. It is a fast way to loop through records. The dataset can be used like an in memory representation of the database. You can use DataViews to filter and sort records for presentation. You can also establish relationships with the dataRelation object. You can use the dataset with a data adapter to update the database. These objects can keep track of changes and original values. When updating the database these objects can help to resolve conflicts or concurrency issues. 11. Working with ADO.NET Now, I'm tired...You can find the answers to all of these questions...If you really want to. __________________ "When that first bullet goes past your head, politics goes right out the window."

# re: Interview Questions: ASP.NET 9/28/2005 12:17 PM Job Hunter in Seattle Good God. So many threads going on. I think there are a lot of desperate job searchers are out there (especially freshers). Every body is asking for questions to be sent to their email id. You already have got tons and tons of question in this page. Have you all done learning those. The basic thing is nobody knows what to study [what are the important topics to focus, how to study for the interview....[ we never know what Q would come from the interviewer] . Me too..Thats the reason i am here. By just going through the questions and answerers you can not win. All you need to do is once you done reading the particular topic for eg. ADO.Net, then search for questions and see if you could answer. Or just don't read the answer and try to remember that. Read that topic fully and try to understand. I got some basic questions, may seem very easy but try to answer [try to tell out loud in 3 or 4 lines] with out googling 1. 2. 3. 4. 5. 6.

What is HTML ? What is XML ? What is the difference between a class and struct ? What is the difference between a Get and a Post ? What is a managed code ? int n *=2; int x = n & 1; What is the value of x ?

7. What is a friend in C++ ? Knowledge is Power. All the best for the hunters.

# re: Interview Questions: ASP.NET 9/29/2005 1:24 PM Job Hunter in Seattle 1.Why would you use an array vs linked-list ?

Linked List: ? They allow a new element to be inserted or deleted at any position in a constant number of operations (changing some references) O(1). ? Easy to delete a node (as it only has to rearrange the links to the different nodes)., O(1). ? To find the nth node, will need to recurse through the list till it finds [linked lists allow only sequential access to elements. ], O(n) Array ? Insertion or deletion of element at any position require a linear (O(n)) number of operations. ? Poor at deleting nodes (or elements) as it cannot remove one node without individually shifting all the elements up the list by one., O(n) ? Poor at inserting as an array will eventually either fill up or need to be resized, an expensive operation that may not even be possible if memory is fragmented. Similarly, an array from which many elements are removed may become wastefully empty or need to be made smaller, O(n) ? easy to find the nth element in the array by directly referencing them by their position in the array.[ arrays allow random access ] , O(1)
