OK, earlier I figured out how to call an event that I have defined in a subclass. Now I want to call an event that already exists in the super of the subclass.

Specifically, I have subclassed ListBox. ListBox has an ExpandRow event. If the user double-clicks a collapsed folder row, I want to expand the row. So actually I have two questions:

1. How can I tell if a row is a folder or a plain row?
2. How can I call the ExpandRow handler from the DoubleClick handler?

Thanks,
Chuck
