Looking at the questions, Got some done. Was wondering if you could send some of the answers. Thanks.

LOOK HERE, but then again if you had done a search before posting your question, you would have found them.

Hi there,

Is there not a list of short answers?

Any help would be appreciated.

Read his post he gave a link in it (yes I know he edited his post)

I looked it only gives question to ASP.NET and C#.

I am looking for the quiz test.

1. Explain the differences between Server-side and Client-side code?
2. What type of code (server or client) is found in a Code-Behind
class?


If you remember. That would be great.

If you can provide me with a list of questions, I can provide you with the answers.

1. Explain the code behind wors and contrast that using the inline style.
2. Different types of HTML,Web and server controls (also how Server control validation controls work)
4. Difference btn user and server controls
4. How server form post-back works (perhaps ask about view state as well).
5. Can the action attribute of a server-side <form> tag be set to a value and if not how can you possibly pass data from a form page to a subsequent page.
6. What is the role of global.asax.
7. How would ASP and ASP.NET apps run at the same time on the same server?
8. What are good ADO.NET object(s) to replace the ADO Recordset object.

Answers:
3. Server controls are built-in. User controls are created by the developer to allow for the reuse of controls that need specific functionality.

4. By default all pages in .NET post back to themselves. The view state keeps the users input updated on the page.

5. No, You have to use Server.Transfer to pass the data to another page.

6. Store global information about the application

8. There are alot...but the base once are SqlConnection, OleDbConnection, etc...
In addition to the above some couple of basic questions, a couple of additional questions listed below. Good luck!

~~~~~~~~~~~~~~~~~~~~

1. Server-side code runs on the server, Client-side code runs on the client.

2. Server

3. Client...so the user doesn't have to wait for the page to be posted to the server and then returned.

4. Enables the ability to maintain the state of the page and all data within it.

5. Server.Trasfer allows you to pass variables to another page. Server.Redirect just redirects the user to another page.

6. When there is no need for a UI to perform the required task.

8. By default Datasets are disconnected.

9. Any variables that need to be set for the application or session objects. Example: For the path of a image directory
Application("ImagePath") = "C:\Images\"


13. VB.NET use the Implements keyword to inherit from another class or interface. C# use : to inherit
example
Code:

VB.NET

class myClass
Inherits baseClass

End class

C#
class myClass : baseClass


14. An assembly is the collection of all information required by the runtime to execute your application.

15. Inline is mixed with the html, code-behind is separated. Use code-behind.

17. An XML format. Can be used by other platforms so send and receive data to a .NET application

23. Microsoft Intermediate Language

24. You mean the steps of the page lifetime? or that .NET is event driven?

25. Fill method

26. Yes

27. ItemTemplate

28. AlternatingItemTemplate

29. Set the datasource property and call the DataBind method

30. Page...but all .NET objects inherit form the Object Base Class.

31. Session.Contents.Remove

32. You can't (not that I am aware of...since there is no Page level directive to do this)

34. Set AutoGenerateColumns Property to false on the datagrid tag

36. <asp:HyperLinkColumn>

39. SOAP is preferred protocol

40. False

41. Web Services Description Language

42. CurrentPageIndex

43. www.uddi.org

45. DataTextField

46. Only a Get method...no, Set method

47. CompareValidator

48. False, the webservice comes with a test page and it provides HTTP-GET method to test.

49. Many

Most (if not all) of those questions are answered in the ASP.NET interview questions posted in the .NET area.
I provided a link to it above.

My personal opinion is...If you can't answer at least 1/2 of those questions, then you shouldn't be applying for a .NET job.

Thank you for your help and your time. I am just trying to learn from these questions.
