Question DataGridViewComboBoxCell Problem

[Progress2007]

Hi
I have a DataGridView in which there are two ComboBoxColumns in each rows
I want to do that , suppose first comboboxcell contains value from ClientTable
and second combo box contains value from Project Table

Now wht i want taht when someone selects any client from first combo then their respective clients should be populated and same for vice versa

my problem is that i am able to do this first time

but at the second time it is giving a error
"DataGridComboxCell value is not valid"

Please help me how to do this...

This will drive you bonkers. I suggest that you do not do it, because all the combos in the grid share one BindingSource, so editing one combo corrupts the other lists, and weird stuff starts happening all over the place
