Hi Telerik Team,

I am getting a strange exception, when have a grouped gridview and refresh the datasource. 
I delete in a background operation some rows and go to the database to refresh the datasource, which is binded to the grid. I get a "Specified argument was out of the range of valid values. Parameter name: index" - Exception on the setter of the datasource. 

I similar problem was discriped in this thread, but I couldn't solve it for WPF.

Hi,

 I have tested refreshing the ItemsSource of a grouped GridView with some groups expanded but so far I did not observed any errors.  I have tested with the latest binaries.

May I ask you if you have the problem with our most recent version - Q2 2012 Service Pack?

Hello,

According to the Q2 2012 Release Notes : "Expand group row with no columns throws exception is now fixed."  May I ask you to download the latest assemblies and test with them?
Please let me know about the result.

All the best,
