One of the ways to do it could be using Javascript.

Whenever any control triggers a server processing, at that event before sending the request to server, use Javascript and disable all the server buttons.
Once processing is complete you can enable them again.

Using jQuery would be more simplerer for such scenario. Try!

But how could I know that the processing is completed.

If you are having full postback for server processing then once the operation is complete (lets say fetching of data from DB), after that, enable all the buttons back from server side. Page will re-render and all good.

If, you must be having some AJAX postback or XMLHttpReuqest kind of thing, then once the response is recieved back from server, you can re-enable the buttons.

For AJAX, you can trap event as described here: http://www.codeproject.com/KB/ajax/AfterAjaxUpdate.aspx
For XMLHttpRust or similar: you already have a method where you get back a response and you act accordingly.

Thanks...I have written a javascript function to disable all contrls and attached it with onclick event of every buttons...But when page is not postback due to some validation then also all controls are getting disabled.
