这很紧急，

推荐答案

我用另一种方法
解决了这个问题

I solved this problem with another way,

<TextBlock  x:Name="textBlk"  Foreground="Transparent" Text="{Binding Name}"

                                       TextWrapping="Wrap"  MouseLeftButtonDown="textBlk_MouseLeftButtonDown"  HorizontalAlignment="Stretch"  VerticalAlignment="Stretch" Margin="0,0,0,0" FontSize="72"  FontWeight="ExtraBold" />

并在
后面的代码中

And in code behind

private void textBlk_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
       {
           TextBlock tb = new TextBlock();
           tb = (TextBlock)sender;

           string strBlockName= tb.Text;
           MessageBox.Show(strBlockName);
       }

当用户单击树图节点块时，他会得到用
编写的文本
文字块

When user would click in the treemap node block he would get the text written in

Textblock
