Object doesn't support property or method 'registerControlProperties'

[Edney]

We just upgraded to .Net Framework 4.5. We are using UI for ASP.NET AJAX Q3 2012 SP2. I have a GridAttachmentColumn that works fine in our development environment. When deployed to QA we get the below error when clicking on the + sign to add a new record to the grid and the Grid Attachment control does not appear.
Error: Object doesn't support property or method 'registerControlProperties'
Anonymous function [Line: 395, Col: 1], Telerik.Web.UI.WebResource.axd
Global code [Line: 5, Col: 2], Telerik.Web.UI.WebResource.axd

Thanks in advance for any help on this issues.

Hi,

Can you verify that you are using the .NET 4.5 binaries of the Telerik assemblies? Also try downloading the latest version of the suite and let us know if the same error is still observed.

Dear All,

 

Above issue has been fixed by adding below value in Web.config file.
