Hello Shanker,

The first problem is probably related to the way you bind your RadGrid - I suppose you use simple data-binding and thus you RadGrid disappears when you click on some button.

documentation:
Simple Data-binding
Advanced Data-binding

demos:

As to the postbacks - you could use RadAjaxPanel or RadAjaxManager:
AJAX Manager
