You actually can associate specific data with any control, just use My_Control.Attribute (Key, Value) and to retrieve in the handler Object.Attribute (Key) of course in this case everything is a string.

Alternatively you could also just extend the controls to include additional fields and then upcast Object to the appropriate extended control type.
