custom sorting of ListBox controls

Has anyone found some documentation on how to properly subclass a ListBox
control and provide custom sorting (when the list items come from a
DataSource)?

The only way I can figure out how to do this is by sorting an array of some
sort and then setting the DataSource. I don't like this because it fires
the DataSourceChanged event.

What I really want to do is get access to the underlying list items, sort
them, and then have the control refresh itself. I already have access to
the underlying list items since I have set the DataSource myself. But
changing the order of the items in the DataSource does not appear to result
in the items in the control being resorted.

Any suggestions?
