You need to use AJAX for that. Once the page is rendered, there is no separation like user controls. Everything will be considered as a single page, and any controls on that will refresh the entire page.

Ajax is not working? 
Can u please tell, Exactly what happens!!!
Now,
Two questions...
1.Where u have take the reference for JS and CSS? Is JS in separate(.js) file?
2.have you used master page in that page?
If u have not use masterpage then u can use masterpage instead Usercontrol,
It will be best if u use Masterpage.

foreach (DataRow row in SearchBooks.Tables[0].Rows)
{
TreeNode newNode = new TreeNode(row["Title"].ToString() , row["ISBN"].ToString());
newNode.PopulateOnDemand = true;
newNode.ImageUrl= row["ImagePath"].ToString();

Hi, iam using ajax based help messages in my web applicatins.
For displaying this help messages iam using Pop up control extender,
the help messages are displaying at appropriate positions when viewing in mozilla but when it comes to internet explorer ther positions are getting changed.
can anyone suggest me a solution for this?
Thank u

What do you mean by 'ajax based', why does your help message need to make an asyncronous call, just to get the help text as needed ?
We can't possibly help you without seeing the code you're using.

Seriously, all these questions are easily answered by google, and if you don't know the answers to any of the questions you asked, you can't possibly be using ASP.NET. Buy a book, learn to use google, ask when you're at a base level of being able to understand the replies.

hey wait - Just go through some books and forums, Read Some Articles Posted here
You will find many useful Information, Just go through that Yaar.
If find any problem there then Post here.
View state is used for state Maintain. It stores a values for a page.
Postback Means the page is been redirected to server for post.
Page.Isvalidate Checks All validaters and it fires Validaters forcefully, Cause some Browsers not supports all validaters Invocation.
refer books, try urself.

Please stop spamming the boards. IF you have this many questions, buy a book. IT's plain you are starting out, do yourself a favour and learn some stuff before asking all these things online.
You can't, best you can do is inject javascript to run the code. For you to even ask this shows you have no idea how ASP.NET works. Buy a beginner book, and read it.

I am using login and loginstatus controls in my application.
When I logged In It change the login status control text to logout which is fine but when I click the logout button it does not take me to the login page again.And how I can stop user to go back by clicking back button in the browser once he is logged off.
How I can store login username in session variable by using login control?
THanks In advance

To prevent the user from using the back button and gaining access after logoff you need to add checks to each page that verify the user has logged in, if not redirect them to the login page.
After the user has logged in you can get the username from the security principal, like WindowsIdentity.Name

You want to check if the user used copy/paste ? You really can't tell, the best you can do is stop copy/paste from working ( I didn't think it did with a password box ).
