Hi Kevin,

You posted this question quite some time ago (I've been away from the UT for several weeks), so you may have already gotten an answer elsewhere, but if you haven't, I'll tell you what the problem is. You need to set the DisplayMember and ValueMember properties, just like you would any ComboBox control:

DataGridViewComboBoxColumn comboboxColumn = new DataGridViewComboBoxColumn();
comboboxColumn.DataSource = dsLocations;
comboboxColumn.DisplayMember = "Address";
comboboxColumn.ValueMember   = "LocationID";
