Highlight the group header

You can highlight a GroupHeader section when the group header is clicked by using TableControlCellClick event. You can check if the selection is a GroupCaptionCell and can highlight the GroupHeader.

void gridGroupingControl1_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e)
{
   GridTableCellStyleInfo style = e.TableControl.Model[e.Inner.RowIndex, e.Inner.ColIndex];
   if(style.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionCell)
   {
      e.TableControl.Selections.Add(GridRangeInfo.Row(e.Inner.RowIndex));
      Console.WriteLine("Header clicked");
   }
}

Private Sub gridGroupingControl1_TableControlCellClick(ByVal sender As Object, ByVal e As GridTableControlCellClickEventArgs)
   Dim style As GridTableCellStyleInfo = e.TableControl.Model(e.Inner.RowIndex, e.Inner.ColIndex)
   If style.TableCellIdentity.TableCellType = GridTableCellType.GroupCaptionCell Then
      e.TableControl.Selections.Add(GridRangeInfo.Row(e.Inner.RowIndex))
      Console.WriteLine("Header clicked")
   End If
End Sub
