Bill,
I never succeeded in that with the DataGrid direct or any column change
event in 1.x, despite all kind of column change events I have seen here. (I
thought that this part is fixed with the DataGridView and 2.0).
However you can use the textbox events if it is a textbox or just the paint
event, which is maybe a little bit expensive (don't think to much of that,
painting itself is much more expensive).
Have a look at samples on our website by instance this two.

Or whatever else you find accoording this.
I hope this helps,
Cor
