如何引用控件模板中的元素

Question

假設我想將CheckBox放在Button的內部。無論如何，我可以在代碼中引用該複選框嗎？即在Window1.cs中，我想寫下類似於：testButton.innerCheckBox.DoStuff();

<ControlTemplate TargetType="{x:Type Button}">       
     <Microsoft_Windows_Themes:ButtonChrome SnapsToDevicePixels="true" x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Fill="{TemplateBinding Background}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}" ThemeColor="NormalColor"> 
     <Grid Width="32.083" Height="13.277"> 
      <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="Stretch" Margin="{TemplateBinding Padding}" VerticalAlignment="Stretch" RecognizesAccessKey="True" d:LayoutOverrides="Width, Height"/> 
      <CheckBox x:Name="innerCheckBox" HorizontalAlignment="Left" VerticalAlignment="Top" Content="CheckBox"/> 
     </Grid> 
     </Microsoft_Windows_Themes:ButtonChrome> 
    </ControlTemplate>

CheckBox innerCheckBox = testButton.Template.FindName("innerCheckBox", testButton) as CheckBox;
