I solved this problem with another way,

HTML

<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" />

And in code behind

C#

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

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

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