If you have two rows (one fixed and one normal), fixed row is row 0 and normal row is row 1. But you not be able see that in MouseDown event, because MouseRow returns row, containing cell with focus rectangle, which is moved on Click event. Remove code for MouseDown event, restore your first code for Click event and put breakpoint on row with Call myGridHighLight(grdOtherAdd, intRow). When you click on fixed row, intRow is 0, and when you click on normal row, intRow is 1 (if you use your first code: intRow = grdOtherAdd.MouseRow()). This first code works by me fine and i wondered why this code does not work by you.
