  <p>The problem is, the placeholder TextBox must be easy to reuse. Either with XAML or Code.
  Maybe it's something like this</p>
  
  <pre><code>&lt;my:TextBoxPlaceholder Placeholder="this is the placeholder"/&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;TextBox Placeholder="this is the placeholder"
           Type="/*staticresources*/PlaceholderTextBox"/&gt;
  </code></pre>
  
  <p>This is what I'm referring to. (the screen shot I got from Instagram Beta). </p>

  <p>As you can see, on the second picture, the "Add a comment" placeholder is on the top most of TextBox, it covers the stripe line. Is the placeholder a picture or a TextBlock on top of it?</p>
