Hi,
If you have add ajax control toolkit to your web application. Then you should see this
http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/PopupControl/PopupControl.aspx[^].

By use of Popup control you can easily implement it.

If have not implement ajax control toolkit, then follow thatraja or Rohan Leuva answer.

Ask if you need any further help.
Thanks.
