Menu 樣式和範本

  • 發行項

本主題描述控制項的 Menu 樣式和範本。 您可以修改預設值 ControlTemplate ，讓控制項具有唯一的外觀。 如需詳細資訊，請參閱 建立控制項 的範本。

控制項 Menu 沒有任何具名元件。

當您為 建立 ControlTemplate 的 Menu 時，您的範本可能包含 ItemsPresenter 中的 ScrollViewer 。 （顯示 ItemsPresenter 中的每個 Menu 專案;啟用 ScrollViewer 在 控制項內捲動）。 ItemsPresenter如果 不是 的 ScrollViewer 直接子系，您必須提供 ItemsPresenter 名稱 。 ItemsPresenter

下表列出 控制項的 Menu 視覺狀態。

VisualState 名稱 VisualStateGroup 名稱 描述
有效 ValidationStates 控制項會使用 類別， Validation 而 Validation.HasError 附加屬性為 false 。
InvalidFocused ValidationStates 附加 Validation.HasError 屬性具有 true 控制項的焦點。
InvalidUnfocused ValidationStates 附加 Validation.HasError 屬性具有 true 控制項沒有焦點。
