Cause l'erreur « Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead. » lors de la fermeture d'un DocumentPanel avec la croix en haut à droite.<br>
Solution: mettre l'ItemsSource sur le DockLayoutManager.

<filebox fn=MainWindow.xaml lang=xaml>
