Because when I was checking out the BusinessBindingSource on the SF Forum I saw something that said I had to populate the BO before pointing the DataGridView to the BusinessBindingSource (or something to that effect), so I just blindly did that rather than doing the obvious and setting the properties in the designer, which works just fine!

Duh!!! :-/

Thanks again,
