I have code written for an imaginanry transport company for C++/CLI .NET where the passengermaster table has route and stage identifiers drawn from route and stage tables all feeding from a mySQL database
When a new passenger is registered, it must be on the person table (picked from a combo cell on the grid), then a route is selected for the passengerfrom a second combo cell, people and route combos dont change, but the combo cell for stages will show differant values depending on the route selected.
My datagridview is based on a Linda Liu solution found here
www.ms-windows.info/Help/different-combobox-row-datagridview-9185.aspx . Scroll down to Solution 2.
