如何从已包含在该单选按钮模板中的按钮的单击事件中识别单选按钮

Question

这是一个 Windows Phone 7 应用程序，这是我正在使用的模板代码：

<Style x:Key="RadioButtonStyle1" BasedOn="{StaticResource PhoneRadioButtonCheckBoxBase}" TargetType="RadioButton">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="RadioButton">

我想创建一个每个按钮都将使用的单击事件，但在该事件处理程序中，我需要能够识别包含被单击按钮的单选按钮。

可能有“更好”的方法来实现您想要做的事情，但您可以将传递给点击事件处理程序的sender 转换为FrameworkElement，然后您可以访问它的@987654323 @ 然后你可以适当地使用它来获取你需要的关于相关项目的任何信息。
