Can anybody help me with understanding why is it that when selecting an option for the AutoSizeMode property of a ComboBox type column in a DataGridView (using the designer, not code), or the DataGridView's AutosizeColumnsMode property (again, not programmatically), when closing the form on which the DataGridView resides, I get the Exception: "DataGridViewComboBoxCell value is not valid".
[TRUST ME. THE VALUE IS VALID!!!]
Only when selecting "NotSet" for the AuitoSizeMode property of the ComboBox column, or "None" for the DataGridView's AutosizeColumnsMode property, It works ok.
Is it a known bug. Or is it that I'm doing something, I can't even think of, wrong?
