I’m having a small problem with the DataGridViewBindingManager. When I add descriptors to the binding manager I have to add a list converter to a specific column.  But this dropdown needs to have different elements in it’s drop down list depending on the row of the grid.  Is there any way that I can allow the listConverter to determine it’s context.

What you are asking for is what I call a "multi-column dropdown".  I don't believe that the .NET Windows controls support this capability, but I am sending you sample code for doing this on both DevExpress and Infragistics.
 
Here is the Devex example.

Here is the Infragistics example.
