I have extended the UltraGrid to include an UltraComboBox that I use as the grid's dropdown control.  I would like to serialize this class and save/load the whole thing to a database.  This works fine with the grid itself, but I get an error when I try to serialize the extended grid class (including the combo).

I would even be happy if I could skip the combo and just serialize the grid, but since they are both in one class, I don't know how to serialize just part of a class.

Any ideas?
