Beispiel

Im folgenden Codebeispiel wird die BindingManagerBase für eine bestimmte Datenquelle abgerufen, und die Informationen zu jeder an die Datenquelle gebundenen Control-Eigenschaft werden gedruckt. Im Beispiel werden mithilfe der Bindings-Eigenschaft der BindingManagerBase sämtliche Steuerelemente abgerufen.
