I have a simple test form on which I have a combobox control. The control is populated through a business object. There are some other controls on the form from another BO which contains the foregn key to the BO which populates the combo. Everything seems to work upon form load except that the combobox in question is enabled and the other controls are not. I would expect that the combobox should be disabled as well. Changes are accepted to the value of the combobox even though I have not clicked Edit on the toolstrip.
