The existing data contains values that are not allowed to be selected for new records. If I bind the whole combobox-column to the reduced dataset I get errors, as some old value keys have no counterpart in the reduced dataset comboboxbox.
Is there a way to use the combobxcolum but to change the combo box for the new record row. If no, then I can add combo box cells to each row with the right selection.
