I have a datagridview linked to a bindingsource that doesn't include the table i want my combobox (which is in my datagridview) to be databound to. Is there anyway to specifically identify each column's datasource in a dgv? I would like this combobox's datasource to be a column in a table included in the same dataset as the datagridview's source, but not in the same tableadapter. Is there anyway to include columns from other tables into one tableadapter maybe?
