I think so, but I'm not sure. Check if you have ActiveColumn property in a VFP5.0 Grid. If your header caption is always the same, as the field name, you may use in Header.Click() this.parent.parent.SetOrder(this.caption). You may want to programatically create Header class and substitute Header1 with your Header class in run-time. Check Cetin's two grids class example in File section for futher details.
