The element which you need to hide is of type IndentPresenter
. You can attach to the Grouping event of RadGridView and hide its visibility in the following manner:
sender, GridViewGroupingEventArgs e)
var element =
.clubsGrid.ChildrenOfType<IndentPresenter>().Where(c => c.Name ==
element.Visibility = System.Windows.Visibility.Collapsed;
Please give it a try and update me whether it has worked for you.
