TabControl 样式和模板

2025-05-07

本主题介绍 TabControl 控件的样式和模板。可以修改默认 ControlTemplate，使控件具有唯一的外观。有关详细信息，请参阅为控件创建模板。

TabControl 部件

下表列出了 TabControl 控件的命名部件。

部件	类型	DESCRIPTION
PART_SelectedContentHost	ContentPresenter	显示当前所选的 TabItem 的内容的对象。

当你为 ControlTemplate创建 TabControl 时，模板可能在 ItemsPresenter中包含一个 ScrollViewer。（ItemsPresenter 显示 TabControl中的每个项;ScrollViewer 在控件内启用滚动）。如果 ItemsPresenter 不是 ScrollViewer的直接子级，则必须给 ItemsPresenter 赋予名称 ItemsPresenter。

TabControl 状态

下表列出了 TabControl 控件的视觉状态。

VisualState 名称	VisualStateGroup 名称	DESCRIPTION
正常	CommonStates	默认状态。
禁用	CommonStates	控件已禁用。
有效	ValidationStates	该控件使用 Validation 类，Validation.HasError 附加属性为 `false`。
无效聚焦	ValidationStates	如果控件具有焦点，则 Validation.HasError 附加属性为 `true`。
无效未聚焦	ValidationStates	如果控件不具有焦点，则 Validation.HasError 附加属性为 `true`。

TabItem 部件

TabItem 控件没有任何命名的部件。

TabItem 状态

下表列出了 TabItem 控件的视觉状态。

VisualState 名称	VisualStateGroup 名称	DESCRIPTION
正常	CommonStates	默认状态。
鼠标悬停	CommonStates	鼠标指针悬停在控件上。
禁用	CommonStates	控件已禁用。
已设定焦点	FocusStates	控件有焦点。
失去焦点	FocusStates	控件没有焦点。
已选定	选择状态	已选择控件。
未选定	选择状态	未选择控件。
有效	ValidationStates	该控件使用 Validation 类，Validation.HasError 附加属性为 `false`。
无效聚焦	ValidationStates	如果控件具有焦点，则 Validation.HasError 附加属性为 `true`。
无效未聚焦	ValidationStates	如果控件不具有焦点，则 Validation.HasError 附加属性为 `true`。

TabControl ControlTemplate 示例

以下示例演示如何为 ControlTemplate 和 TabControl 控件定义 TabItem。

<Style  TargetType="{x:Type TabControl}">
  <Setter Property="OverridesDefaultStyle"
          Value="True" />
  <Setter Property="SnapsToDevicePixels"
          Value="True" />
  <Setter Property="Template">
    <Setter.Value>
