I've talked of using the MouseMove() of the text box for the related columns to define a tooltip for the grid, however there is no MouveMoveOut() in order to reset the tooltip. This would have make the tooltip only appear when the mouse if over those columns. However, I need to put it blank when moving out of the field.

Your idea of the coordinates might work. I'll keep that in mind. Thanks.
