Hi,
 Thanks for your response,
As you send me this demo project, like this my project is also working fine.
I getting problem when doing following.
1- i have one radGrid with Button Column(for edit record).
2- when i click in this button where i have written server side code modalpopup.show(), that time iam getting this error.  
"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'ctl00_ContentPlaceHolder1_RadTextBox1' can't be added to the application."
Somewhere i have read to set ScriptManager proparty script mode to release then it is solving this issue, but creating another following error.
Iam also sending some screen shot to you, please see it.
