datagridview combo box column

Hi,

Here is what I understand:
Combo box B, depends on Combo box A.
Both Combo boxes are sitting in a data grid.
You change rows after editing both combos

Assuming that the idea works on a single row and that the reloading only happens when you change rows, we should look there.

Unless each row has a datasource object associated with it, the combo's will have only one source. Moving to the next row forces all the combos to read from that one source.

A solution might be to save the first row on completion of selection before moving to the next row.
or
Maybe add a datasource to the template, thereby allowing autonomy between rows.

just some idea's
