TabControl 樣式和範本

  • 發行項

本主題說明 TabControl 控件項的樣式和範本。 您可以修改預設的 ControlTemplate，為控制項提供唯一的外觀。 如需詳細資訊，請參閱為控制項建立範本。

TabControl 組件

下表列出 TabControl 控件項的具名組件。

部分 類型 描述
PART_SelectedContentHost ContentPresenter 顯示目前選取之 TabItem 內容的物件。

當您為 ControlTemplate 建立 TabControl 時，您的範本可能包含 ItemsPresenter 內的 ScrollViewer。 (ItemsPresenter 會顯示 TabControl 中的每個項目；ScrollViewer 會在控件項內啟用卷動)。 如果 ItemsPresenter 不是 ScrollViewer 的直接子項目，您必須為 ItemsPresenter 命名，ItemsPresenter。

TabControl 狀態

下表列出 TabControl 控制項的視覺物件狀態。

VisualState 名稱 VisualStateGroup 名稱 描述
Normal CommonStates 預設狀態。
已停用 CommonStates 已停用控制項。
有效 ValidationStates 控制項會使用 Validation 類別，且 Validation.HasError 的附加屬性為 false。
InvalidFocused ValidationStates Validation.HasError 附加屬性為具有焦點控制項的 true。
InvalidUnfocused ValidationStates Validation.HasError 附加屬性為不具有焦點控制項的 true。

TabItem 組件

TabItem 控制項沒有任何具名組件。

TabItem 狀態

下表列出 TabItem 控制項的視覺物件狀態。

VisualState 名稱 VisualStateGroup 名稱 描述
Normal CommonStates 預設狀態。
MouseOver CommonStates 滑鼠指標移到控制項上。
已停用 CommonStates 已停用控制項。
焦點 FocusStates 控制項已取得焦點。
未取得焦點 FocusStates 控制項未取得焦點。
Selected SelectionStates 已選取控制項。
未選取 SelectionStates 未選取控制項。
有效 ValidationStates 控制項會使用 Validation 類別，且 Validation.HasError 的附加屬性為 false。
InvalidFocused ValidationStates Validation.HasError 附加屬性為具有焦點控制項的 true。
InvalidUnfocused ValidationStates Validation.HasError 附加屬性為不具有焦點控制項的 true。

TabControl ControlTemplate 範例
