如何将按钮内容绑定到工具提示的Radiobutton？

Question

其实我想绑定单选按钮的内容部分到工具提示的单选按钮 我是一个在xaml beginer所以实践的理由我想学习它......为数据绑定更好的做法..我的代码如下：

<Button Name="BtnDemo" Height="Auto" Width="Auto" Content="Hello Dear!" HorizontalAlignment="Left" VerticalAlignment="Top" > 
     <Button.ToolTip> 
      <ToolTip > 
       <StackPanel > 
        <TextBlock Name="txbDemo" FontWeight="SemiBold" Foreground="Brown" Text="Tool Tip Of Hello Button"/> 
        <TextBlock Text="This Is The Tool Tip Of Hello Button...!"/> 
        <RadioButton Content="{Binding Content,ElementName=BtnDemo,UpdateSourceTrigger=Default}" IsChecked="True"/> 
       </StackPanel> 
      </ToolTip> 
     </Button.ToolTip> 
    </Button> 

我想做的事情是没有C＃或VB.net ... thanx提前....

试试这个：

<Button Name="BtnDemo" Height="Auto" Width="Auto" Content="Hello Dear!" HorizontalAlignment="Left" VerticalAlignment="Top" > 
    <Button.ToolTip> 
     <ToolTip DataContext="{Binding Path=PlacementTarget, RelativeSource={RelativeSource Self}}" > 
      <StackPanel > 
       <TextBlock Name="txbDemo" FontWeight="SemiBold" Foreground="Brown" Text="Tool Tip Of Hello Button"/> 
       <TextBlock Text="This Is The Tool Tip Of Hello Button...!"/> 
       <RadioButton Content="{Binding Path=Content}" IsChecked="True"/> 
      </StackPanel> 
     </ToolTip> 
    </Button.ToolTip> 
</Button>
