You can give a control design-time behavior by creating a separate designer class for the control. Since the control itself can only exist as an instance of your runtime, you can't really have a property directly on it which is set only at design-time (where would it get stored?). However, designer classes are only invoked and used by the designer, so you can encapsulate non-runtime behavior there.
