Hi Patrick,
The GridDropDownColumn uses the same mechanism internally. It attaches to RadComboBox's ItemsRequested event and passes the DataSourceID you have provided for the column. If you need to retrieve your items in a custom manner, the approach you have taken is correct. A GridTemplateColumn with a combo provides you with enough flexibility to do that.
