>What I did in 3.0, was to call a form to enter the value of the field from the SetFocus() event. So, no keyboard value was able to be keyed from that field. I was only showing the value so it was ok.
One more thing is that the form called might have a definition as if the user think is he entering the value in the actual field of the grid.
By defining a window with no border, no title, no move, having the same dimension as the grid field and at the same place may get you what you want.
