For that i have to add ScriptManager control in .ascx. But if I use this control on a same page more than once, I get the exception 'Only one instance of ScriptManager control can be added on page'. This is obvoius as 'ScriptManager' control will be loaded multiple times.
So my query is : Can we add ScriptManager dynamically in .ascx by checking if its alredy exists on page?
