Hello Santiago,

I am not sure what you are talking about. Do you mean you want to hide the GridGroupSplitterColumn?

I need restore default grid view without grouping.

After executing the method grid.Rebind() the grouping columns do not disappear.

Kind Regards.

Hi  Santiago,

You need to clear group expressions similar to this example:

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.
