TableControlCellMouseUp and ContextMenu with GridGroupingcontrol

Initially I assigned a contextmenu to the GridGroupingControl. It worked fine. Since I need to differentiate if the context menu is on column header/regular cell/blank area, I added TableControlCellMouseUp handler. I found the context menu is not working after the handler is added. I can popup the context menu in header/cell, but I have no way to popup it in blank area. what''s the proper way to popup context menu in any situation? Thanks, albert

Currently, I think you will have to handle 2 events to catch both these situations. The grid.TableControl.MouseUp will catch the click where there are no cells.
this.gridGroupingControl1.TableControlCellMouseUp += new Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventHandler(gridGroupingControl1_TableControlCellMouseUp);
this.gridGroupingControl1.TableControl.MouseUp += new MouseEventHandler(TableControl_MouseUp);

private bool TableControlCellMouseUpHit = false;

private void gridGroupingControl1_TableControlCellMouseUp(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs e)
{
	if(e.Inner.MouseEventArgs.Button == MouseButtons.Right)
	{
		TableControlCellMouseUpHit = true;
		this.contextMenu1.Show(this.gridGroupingControl1, 
			this.gridGroupingControl1.PointToClient(Control.MousePosition));
	}
}

private void TableControl_MouseUp(object sender, MouseEventArgs e)
{
	if(!TableControlCellMouseUpHit && e.Button == MouseButtons.Right)
		this.contextMenu1.Show(this.gridGroupingControl1, 
			this.gridGroupingControl1.PointToClient(Control.MousePosition));
	TableControlCellMouseUpHit = false;
}
