I understand you redefine the Display method in the form. In this case, protected properties are not visible.

Protected prop/methods are visible from the class where they are defined and from derived classes. When you redefine a method for an object in a form, the redefinition applies only to that instance of the class. This is not in the same class or in a derived class. IMO, this is the correct behavior (because this code is in fact in the Form).
