Q1 2013: problem with ColumnSortDescriptor

[Jean]

Hello,
I have a problem with the Q1 2013 version that was not in the previous, Q3 2012 SP1. I'm using Gridview with a GroupDescriptor 
, my gridview is in a telerik tabItem, when i switch from tabitem, and I'm back on my grid I have this error :

Column cannot be null
Nom du paramètre : newColumn

Stack Trace :

                              </telerik:RadTabItem>

Without the GroupDescriptor, there is no problem.

Thanks in advance

Thanks, it works !!

We are running into this same exact exception in Silverlight. I took the hotfix RadControls_for_Silverlight5_2013_1_0401_TRIAL_hotfix and overwrote all of the folders/files at C:\Program Files (x86)\Telerik\RadControls for Silverlight Q3 2012 with the hotfix build files, however we still have the exception.

Could you please let us know if this is the proper hotfix for this issue?

Hi Mark,

May I ask you to check whether the referenced binaries are the right ones? Please check the attached image.
