Use the RemoveGroup event to notify your application that a
group is released. Use the RemoveGroup event to release any extra data stored
by the group. The Remove method fires the
RemoveGroup event for each group removed. Use the RemoveItem event to notify
your application that an item is deleted.
The following sample
displays the group's caption being deleted:
Private Sub ExplorerTree1_RemoveGroup(ByVal Group As EXPLORERTREELibCtl.IGroup)
Debug.Print Group.Caption
End Sub
