title: String format using MultiBinding?
body: <p>I'm trying to display a string in XAML using Label control. Following is my XAML code :</p>
  
  <pre><code>&lt;Label Height="28" HorizontalAlignment="Left" Margin="233,68,0,0" Name="label13" VerticalAlignment="Top"&gt;
      &lt;Label.Content&gt;
          &lt;MultiBinding StringFormat="{}{0} x {1}"&gt;
                &lt;Binding Path="Width" /&gt;
                &lt;Binding Path="Height" /&gt;
          &lt;/MultiBinding&gt;
      &lt;/Label.Content&gt;
  </code></pre>
  
  <p></p>
  
  <p>Width and Height are two properties of my class Movie.
  I want the label to display : "Width x Height" ex. 800 x 640
  However the label control remains empty. Any help is appreciated.
  I WANT TO DO THIS WITHOUT USING A CONVERTER.</p>
  
  <hr>
  
  <p>I have modified my xaml by using a TextBlock instead of Label. But still it wont populate display the output.</p>
  
  <pre><code>&lt;TextBlock Height="28" HorizontalAlignment="Left" Margin="233,68,0,0" Name="label13" VerticalAlignment="Top"&gt;
                  &lt;TextBlock.Text&gt;
                      &lt;MultiBinding StringFormat="{}{0} x {1}"&gt;
                          &lt;Binding Path="Width" /&gt;
                          &lt;Binding Path="Height" /&gt;
                      &lt;/MultiBinding&gt;
                  &lt;/TextBlock.Text&gt;
              &lt;/TextBlock&gt;
  </code></pre>
