Solution 1

there are lot of ways to do it like:

1) using PageMethods
2) ICallBackEventHandler
3) XmlHttpRequest

For implementation refer these:

XMLHttpRequest Call[^]

XmlHttpRequest is AJAX...

Solution 2

The only way i can think of async communication is by

1. using uppdatepanel and other server controls.
2. using xmlhttprequests.
3. using jQuery AJAX.

I know you have specifically mentioned no AJAX( and frankly i dont understand why) still i would give you a couple of links specifying the above 3 mentioned approaches. See if you could use any of them.

AJAX for beginners (Part 2) - Using XMLHttpRequest and jQuery AJAX to implement a cascading dropdown[^]

Also, Could you please let me know why do you want NO_AJAX? is there some requirement or constraint demanding this.

thnx for ur reply..
actualy our server doesn't support ajax.
And Our compny don't want to use ajax in website even i don't know why and they are still using asp.net2.0 for the development purpose.
thnx

In that case it is not possible to do async postbacks.

But asp.net 2.0 can still work with AJAX, you just need to have AJAX extension installed in the server and make the changes in web.config to refer to proper assemblies. check if that is allowed.

I think json is the solution of my prob.
