.NET Framework - AJAX Asyncfileupload - how to refresh updatepanel after UploadedComplete

Asked By Mel on 18-Jan-12 10:24 AM
I am using the latest AJAX control toolkit (4.1.51116.0).  I have a
modalpopupextender, AsyncFileUpload and a gridview inside an update
panel in my web user control (.ascx) page .  The modal popup extender
appears and after the upload I want to update the gridview to display
some of the data I read in from the file.  I have search Goole forever
and tried many solutions and I cannot figure it out.  Please help.
