    I have migrated my application that uses Telerik.Web.Design version 2009.3.1103.35 and Telerik.Web.UI version 2008.3.1125.35 dlls from 3.5 to 4.0. I am receiving the following error while doing any postback operation like cancel in RadGridView row. Pleas find the attached error screen shot.

     I had refered to the patch provided by Simon at http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-vs2010-bug.aspx. But tht fix is not  working for every form in my project.

    Again, I have alos tried by replacing latest telerik dlls, but with this all web pages are working fine except the one in which i have used many telerik controls and that page is not even entering into Page_Load event.

    Please guide us on this issue as I have a very urgent delivery next week.

    Hi Anuradha,

    The provided information is not sufficient to determine what might caused this error. Please provide us with a runnable sample, so we could inspect your code. Additionally, as I can see you, are not using the latest available version - 2009.3.1314.35. This means that the fixes Simon talking about may not exists in your current version 2009.3.1103.35 because it was released a long time ago before Simon's post. 

    All the best,
