Remarques

Lorsque vous créez un délégué ComponentRenameEventHandler, vous identifiez la méthode qui gérera l'événement. Pour associer l'événement au gestionnaire d'événements, ajoutez une instance du délégué à l'événement. Le gestionnaire d'événements est appelé chaque fois qu'un événement se produit, sauf si vous supprimez le délégué. Pour plus d’informations sur les délégués de gestionnaire d’événements, consultez Gestion et déclenchement d’événements.
