Bill's suggestion solved my problem perfectly and fast! Iulia provided an old Ossmann file that didn't work, but is a wonderful bit of programming nevertheless.
Thanks to both Bill and Iulia.

I've already done Refresh() but nothing seems to happen. I always have to restart the application just to make the datagrid display a new set of rows and column. Are there other steps required before issuing Refresh()?
Thanks.

I'm not sure why anybody would say that - Refresh() is right there at the top of the hierarchy.
