如何将按钮内容绑定到工具提示的单选按钮中？

Question

实际上我想将单选按钮的内容部分绑定到工具提示的单选按钮中我是xaml的初学者，所以只是为了练习，我想学习它…为了更好地实践数据绑定…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>

我想做没有c#或VB.net…提前感谢....

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>
