在模板的复选框中添加命令绑定，如下所示：

Template =“ {StaticResource ResourceKey = collapsCheckBox}” x：Name =“ MyCheckBox” Height =“ 30” Width =“ 30” Foreground =“ White” VerticalContentAlignment =“ Bottom” DockPanel.Dock =“ Right” Margin =“ 3 6 3 10“ Command =” myapp：YourCommandClasd.GetCommandInstance“>

并在xaml中声明： 

    <CommandBinding

        Command="myapp:YourCommandClass.GetCommandInstance"   Executed="To_Be_Executed" />

</Window.CommandBindings>

您可以在xaml.cs文件中声明“ To_Be_Executed”方法，该方法将被触发。

应该在xaml代码中将myapp声明为名称空间。

YourCommandClass.GetCommandInstance：可以是返回RoutedUICommand对象的属性。

对不起，我在手机上写了代码。
