Hi!

I tried to hide the GridGroupSplitterColumn like explained in http://www.telerik.com/help/aspnet-ajax/grdpreventgroupsexpansion.html, but it doesn't work. Am I missing something?

Regards, J.

Hi Joze,

Attached to this message, is a small application, which handles one possible approach for this scenario.
I hope it helps.
