Q: 

How can i make dependent ComboBoxes in DataGridView

I have a DataGridView in my windows application, what using DataBinding (Strong-type Dataset). My problem is the following:

I have two DataGridViewComboBoxCell. First "Project" Second "Activity". When i change the value of the "Project" cell, then i want to change the data source of the "Activity" DataGridViewComboBoxCell. But when it happens, all the previous Row in the DataGridView updated and thrown an error.

Any idea?

(sorry, my English is not very good. But i hope, i was understandable)

Your help is appreciated.
