Remarques

Cette méthode est une méthode pratique pour appeler RegisterName.This method is a convenience method for calling RegisterName. L’implémentation vérifie les éléments parents successifs jusqu'à ce qu’il trouve applicable NameScope implémentation, ce qui se trouve en recherchant un élément qui implémente INameScope.The implementation will check successive parent elements until it finds the applicable NameScope implementation, which is found by finding an element that implements INameScope. Pour plus d’informations sur les portées de nom, consultez portées de nom XAML WPF.For more information about namescopes, see WPF XAML Namescopes.

Appel RegisterName est nécessaire pour raccorder correctement des tables de montage séquentiel pour les applications lors de la création dans le code.Calling RegisterName is necessary in order to correctly hook up animation storyboards for applications when created in code. Il s’agit, car un de la clé d’animation de propriétés, TargetName, utilise une recherche de nom de l’exécution au lieu d’être en mesure de prendre une référence à un élément cible.This is because one of the key storyboard properties, TargetName, uses a run-time name lookup instead of being able to take a reference to a target element. Cela est vrai même si cet élément est accessible par référence à partir du code.This is true even if that element is accessible by reference from the code. Pour plus d’informations sur la nécessité d’inscrire les noms pour les cibles de la table de montage séquentiel, consultez vue d’ensemble des Storyboards.For more information on why you need to register names for storyboard targets, see Storyboards Overview.
