C# 自定义单选按钮控件

我正在尝试创建一个自定义单选按钮，其中包含按下状态、正常、选中和未选中的图像

我在编译时遇到问题，抱怨radiobutton不能包含基于文本的内容<代码>图像RadioButton不支持文本内容。

看得见的
崩溃

那我就这样用

<ImageRadioButton Image="/Assets/normal.png" PressedImage="/Assets/pressed.png">Testing</ImageRadioButton>

测试

它抱怨

我做错了什么？

通常意味着您在XAML中放了一些不属于它的纯文本。我能

<VisualState x:Name="Disabled"> 
  <Storyboard> 
    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
    <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/> 
    </ObjectAnimationUsingKeyFrames> 
  </Storyboard> 
</VisualState>
