I am working in asp.net 4.5 in vs 2013 with Ajaxcontroltoolkit 16.1.1.0. I am having a a gridview with rating control. Rating control OnChanged event fires only when autopost=false; if I set it to true it does not. When I use response.redirect it gives a exception:
response.redirect cannot be called in a page callback
I searched for this and used:
Response.RedirectLocation = Page.ResolveUrl("~/stage2scoringsheet.aspx?InnovationId=" + InnovId);
But the page is not post backing. I have checked removing all my update panels but it does not work. When I click on rating some calculation happens and should display in lbl_TotalFinalScore. Currently calculation is done ans stored in db but not able to display in lbl_TotalFinalScore when rating is selected. If close the page and come back again it displays.
Below is C# code.
