title: WPF padding with StringFormat
body: <p>How can I pad a string in wpf by means of StringFormat?
  I'm using a multibinding:</p>
  
  <pre><code>&lt;MultiBinding StringFormat="Name: {0}, age: {1}"&gt;
      &lt;Binding Path="Name"/&gt;
      &lt;Binding Path="Age"/&gt;
   &lt;/MultiBinding&gt;
  </code></pre>
  
  <p>Is there any way to pad the string such that column Age begins at position 50 for instance? I am looking for something that is similar to </p>
  
  <pre><code>string.PadLeft(50)
  </code></pre>
