Did just that.

I'll keep this in mind.

Anyway I came to a problem area. This grid is dynamically created, I assign the rowsource/controlsouce at run-time. The fields created using textbox are of the default variety. It does not use my classes.

Anyway I can get it to use my textbox subclasses?

Merry Christmas
