Hello,
Yesterday I upgraded from RadControls for .NET Q1 2010 to the UI for ASP.NET AJAX Q3 2014. I have three solutions which utilize the RadGrid extensively. In my development environment (VS 2010) all of my projects work great. However, when they are deployed to a Windows 2003 IIS 6 server, I am receiving the following errors when I try to sort any RadGrid in my project:
System.InvalidCastException: Unable to cast object of type 'Telerik.Web.UI.RadGrid' to type 'Telerik.Web.UI.GridTableView'. at Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Other basic functions appear to be working properly including rendering of the grid as well as pagination.
Two of the solutions share an application pool on my web server so I though perhaps that might be an issue (even though I know they have their own memory spaces) so I set up a brand new Windows Server 2003 machine patched fully as of this morning. I am still having the error there.
I have verified that I am sending out the correct version of the DLL and verified that my web.config file has the correct entries per the online demos folder installed on my development machine.
Can you please suggest a solution?
Thank you!
