Data binding should be able to do what you want. In examining the code,
it appears that a right parenthesis should be moved after ToString()
rather than before it. Also, should it read SelectedIndex.ToString()
rather than SelectedItem.ToString()? When declaring the ListBox, did
you use the WithEvents keyword?
