Styles et modèles Menu

  • Article

Cette rubrique décrit les styles et les modèles du contrôle Menu. Vous pouvez modifier le ControlTemplate par défaut pour donner une apparence unique au contrôle. Pour plus d'informations, consultez Personnalisation de l'apparence d'un contrôle existant en créant un ControlTemplate.

Composants de Menu

Le contrôle Menu ne comporte pas de composants nommés.

Lorsque vous créez un ControlTemplate pour Menu, votre modèle peut contenir un ItemsPresenter dans un ScrollViewer. (Le ItemsPresenter affiche chaque élément de Menu ; ScrollViewer active le défilement dans le contrôle.) Si ItemsPresenter n'est pas l'enfant direct du ScrollViewer, vous devez attribuer à ItemsPresenter le nom ItemsPresenter.
