Hi
I was trying to replicate this demo
http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/grouping/grouping-client-side-api/defaultcs.aspx
but I have some problem

As you can see from the attached it seems to work but Company and Cdc doesn't group for anything

If I try to add or delete group nothing happens
If I try to order by Company or Cdc (click on the arrow on the group) I have a js telerik error
TypeError: f.get_owner(...) is null

Hello Stefania,

The problem in the illustrated setup is that the grid is bound to a RadClientDataSource. With the current implementation of the control grouping is not supported when client-side data-binding is used. If using the grouping mechanism of the grid is mandatory for your project I recommend binding the control on the server.

Additionally please note that we are currently improving the grouping capabilities of the grid to support client-side data-binding. I sincerely hope that the functionality will be available in the next official release.
