Hello subin 

 

The ScriptManager control manages the communication between the client page and the server. It manages also manages the JavaScript files used at the client, takes care of partial-page updates. You can directly drag and drop this control on content page. It does not have a visual representation. It only used to manage AJAX processing. You cannot use more than one ScriptManager control on single web page.
