    </Setter.Value>
  </Setter>
</Style>

以下範例是透過使用 TemplateBinding Markup 擴充功能，將SelectedContentTemplate該屬性綁定到該ContentPresenter.ContentTemplate屬性上。

<ContentPresenter Content="{TemplateBinding SelectedContent}" 
     ContentTemplate="{TemplateBinding SelectedContentTemplate}" 
     ContentTemplateSelector="{TemplateBinding SelectedContentTemplateSelector}" />

備註

當分頁選擇改變時，會 TabControl 更新此屬性以參考 DataTemplate active TabItem 的 。 將 TabControl.ContentTemplate 或 ContentTemplate 屬性TabItem設為 ，以指定 。DataTemplateTabItem

其中 利用ControlTemplate該ContentPresenter.ContentSource屬性將該屬性綁定ContentPresenter.ContentTemplate於該屬性。TabControl 如果你為 建立新ControlTemplate檔案，TabControl請務必將該屬性綁ContentPresenter.ContentSource定ContentPresenter.Content為「SelectedContent」或使用 TemplateBinding Markup 擴充功能。

XAML 屬性使用方式

<object property="{TemplateBinding SelectedContentTemplate}"/>
