Yeah, but this is a two-edge sword. Once you put the grid on a form you can *add* colums to it, but you cannot remove the columns that were created by the "class"...

Now then, *changing* the textbox to mytextbox is easy enough to do manually...provided you don't have a grid with 1,234,693 columns ;)
