OK. So I've answered my own question. It seems I wasn't setting the datagridviewcombobox.datapropertyname to that of the datatable. Now my problem is that the two datasources are disconnected. That is, when the grid datasource is populated, it doesn't automatically set the valuemember property of the datagridviewcombobox, so the combobox does not reflect the value in the grid. Any clues as to how to help the control make the association?
Thanks again!
