corresponding comboboxes in datagrid

Question

Hi all, Is there a way to change a corresponding cell's combobox's datasource upon selection in another combocolumn? What I need now is to be able to rebind the corresponding combobox in the 2nd column (and none of the other comboboxes in that column) to a new dataset that will be filled according to the selection in the 1st column. To clarify my question I'll use the following example: Let's say we have a grid with two combobox columns, the 1st column is 'gender' and the 2nd is 'name'. Choosing male on the gender column will populate all the male employees and female will populate female employees in the corresponding cell on the other column in the selected row. Is this possible? Any help will be appreciated... Roy
