如何將按鈕內容綁定到工具提示的Radiobutton？

Question

其實我想綁定單選按鈕的內容部分到工具提示的單選按鈕 我是一個在xaml beginer所以實踐的理由我想學習它......爲數據綁定更好的做法..我的代碼如下：

<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> 

我想做的事情是沒有C＃或VB.net ... thanx提前....

試試這個：

<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>
