Hi Kevin,

You have a couple of options:

1) Make the base event handler protected virtual. That way you can override it in the sub-class rather than create another event handler in the sub-class.

-or-

2) Don't create an eventhandler and simply override the OnResize method in both the base and the sub-class.

Either way is acceptable.
