title: TextBlock with some text as left aligned and the remaining text as right aligned
body: <p>I want to have a textblock which contains text like below:</p>
  
  <pre><code>My associated textbox is                :
  </code></pre>
  
  <p>Text is left-aligned and colon is right aligned.</p>
  
  <p>I know how to get the above output using two textblocks. But I want to know that <strong>is the same behavior applicable to a single textblock?</strong></p>
