Hi Don,

The easiest thing to do might be to set up a form that contains each of the grids exactly as you'd like them to be set up. Then save each grid off as a class. Then in your code, use addobject and removeobject to display the desired grid class. The only thing extra that you'll probably have to do is add some code to your combobox to make sure the appropriate child table is open and that it's the target of a relationship.
