Thanks, it worked!

I already had the datagridcolumn style set, but not the first mappingstyle that appears. Bizarre, though, when I click on the drop down it shows two tables related to the table that I want- "Orders", but not "Orders" itself. It did accept my manual entry of the table name - "Orders".

Any hints or places I can look up to add a combo box, by the way? I want to fill a cell with a selection from a different table. For example, show a list of employee names and allow the user to select one.

Thanks again.
