DefineSupportedTypes must be overridden. Use it to call AddSupportedType with Control type that you support. Remember that all subclasses of any type added are automatically supported. For example, if you want to include all HtmlControls, call AddSupportedTypes(typeof(HtmlControl)). You can use pContext.Instance to get a hold of the control whose property is being edited.
