Windows phone 7 如何从包含在单选按钮模板中的按钮的单击事件中识别单选按钮

这适用于Windows Phone 7应用程序，以下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">
                    <Grid Background="Transparent">

我想创建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”的方法来实现您尝试执行的操作，但您可以强制转换传递给单击事件处理程序的

发送者
，到
FrameworkElement
，然后您可以访问它的
DataContext
，然后您可以适当地转换它，以获得您需要的有关所讨论项目的任何信息。
感谢您的回复，我已经使用了树帮助器，然后可以导航到父级以获得我想要的信息。
