In any data aware (database) application you probably have db-aware controls dropped on some container connected to a TDataSource connected to a TDBNavigator.

Nice aproach. But if you for instance put a TButton on a group box before you put any Edit boxes your code will aways set focus to this Button. Why? Becouse TButton is also TWinControl.
