如何在WPF中绑定单选按钮的Checked事件？

I am using the following markup in WPF:

我在WPF中使用以下标记：

    <StackPanel.Triggers>
        <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="xmlRadioButton">
            <EventTrigger.Actions>
                <BeginStoryboard Storyboard="{StaticResource ShowXmlPanel}"/>
            </EventTrigger.Actions>
        </EventTrigger>
        <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="adiRadioButton">
            <EventTrigger.Actions>
                <BeginStoryboard Storyboard="{StaticResource ShowAdiPanel}"/>
            </EventTrigger.Actions>
        </EventTrigger>
    </StackPanel.Triggers>

Though this works fine when I run the code, I get the following error in the designer window of VS 2008:

虽然这在我运行代码时工作正常，但我在VS 2008的设计器窗口中收到以下错误：

Value 'RadioButton.Checked' cannot be assigned to property 'RoutedEvent'. Invalid event name.

值'RadioButton.Checked'无法分配给属性'RoutedEvent'。无效的活动名称。

Any idea why, and how can I fix this?

知道为什么，我该如何解决这个问题？

RadioButton is a ToggleButton. The designer does support the attached ToggleButton properties, but not the RadioButton ones (except in a RadioButton tag of course).

RadioButton是一个ToggleButton。设计器确实支持附加的ToggleButton属性，但不支持RadioButton属性（当然，除了RadioButton标记）。

You need to use the class name that defines the property/event for the designer to accept it (thought there is no difference at runtime, since RadioButton IS a ToggleButton as I said, but the designer is not a real compiler).

你需要使用为设计者定义属性/事件的类名来接受它（认为在运行时没有区别，因为RadioButton就像我说的那样是一个ToggleButton，但设计师并不是真正的编译器）。

So in your case, use <EventTrigger RoutedEvent="ToggleButton.Checked ..." ;-)

所以在你的情况下，使用
