The problem with that, is it will display in the combo box the Tostring() of
MyObj.
The reason that this is a problem is MyObj is a complicated object with many
possible display strings (e.g its name, its author, its publisher, etc.)
The user was going to select vie a radiobutton what he wants to see
displayed in the ComboBox (names, authors, etc.)
I would re-populate the combo box with strings (MyObj.Name, MyObj.Author )
based on his choice but still have a reference to the underlying object when
one item is selected in the comboBox. I therefore can't let use the
ToString() for how would I know as to what to have the overridden ToString()
return (it might be MyObj.Name, or maybe MyObj.Author etc. )

Any other ideas?
