DataGridView - Designer

Hi,
I have a problem with the DataGridView designer serialization. I have a CustomGrid that derives from DataGridView. Whener I add that to a form, all the properties are serialize in the form's designer. Thus, when I change something like the BackColor in the CustomGrid initializer, it has no effect since a different color was serialized in the designer. Therefore, I have to remove the designer declaration for the change to have an effect.
How could I change that behavior, so that all changes done in the CustomGrid reflect in the designer of the form?
Thanks
