I have an AdvancedDataGrid (ADG) where the top level items
are instances of my custom valueObject Class "State". The second
level items are instances of another custom valueObject Class -
"City". When I select an "City" item in the ADG, I want to find the
parent item in the DataProvider for that City. I'm using
HierarchicalData as my DataProvider. FYI, I'm not looking for how
to capture the event, I'm wanting to find out if there is some
function or utility for finding out the Class of an Object.
