Menu-Stile und -Vorlagen

In diesem Thema werden die Stile und Vorlagen für das Menu-Steuerelement beschrieben. Sie können die Standard-ControlTemplate ändern, um dem Steuerelement ein einzigartiges Aussehen zu verleihen. Weitere Informationen finden Sie unter Erstellen einer Vorlage für ein Steuerelement.

Das Menu-Steuerelement enthält keine benannten Teile.

Wenn Sie eine ControlTemplate für ein Menu-Element erstellen, enthält Ihre Vorlage möglicherweise einen ItemsPresenter innerhalb eines ScrollViewer. (Der ItemsPresenter zeigt jedes Element im Menu an, und der ScrollViewer aktiviert das Scrollen im Steuerelement.) Wenn der ItemsPresenter kein direkt untergeordnetes Element des ScrollViewer ist, müssen Sie dem ItemsPresenter den Namen ItemsPresenter geben.

In der folgenden Tabelle sind die visuellen Zustände für das Menu-Steuerelement aufgeführt.

VisualState-Name VisualStateGroup-Name Beschreibung
Gültig ValidationStates Das Steuerelement verwendet die Validation-Klasse, und die angefügte Validation.HasError-Eigenschaft lautet false.
InvalidFocused ValidationStates Die angefügte Validation.HasError-Eigenschaft lautet true, wenn das Steuerelement den Fokus besitzt.
InvalidUnfocused ValidationStates Die angefügte Validation.HasError-Eigenschaft lautet true, wenn das Steuerelement nicht den Fokus besitzt.

Das folgende Beispiel ist eine Kopie der Standardvorlage für ein Window-Steuerelement:

In der folgenden Tabelle sind die benannten Teile für das Menu-Steuerelement aufgeführt.

Wenn Sie eine ControlTemplate für ein MenuItem-Element erstellen, enthält Ihre Vorlage möglicherweise einen ItemsPresenter innerhalb eines ScrollViewer. (Der ItemsPresenter zeigt jedes Element im MenuItem an, und der ScrollViewer aktiviert das Scrollen im Steuerelement.) Wenn der ItemsPresenter kein direkt untergeordnetes Element des ScrollViewer ist, müssen Sie dem ItemsPresenter den Namen ItemsPresenter geben.

In der folgenden Tabelle sind die visuellen Zustände für das MenuItem-Steuerelement aufgeführt.
