title: Remove "X" button at the end of a TextBox
body: <p><img src="https://i.stack.imgur.com/WI1JZ.png" alt="enter image description here"></p>
  
  <p>I'm developing a Windows Store App using C# + XAML. When I add a TextBox with the property <code>TextWrapping</code> set to <code>NoWrap</code>, a "X" appears at the end of the TextBox when it's focused.</p>
  
  <p>So, I need to remove this "X" and the TextBox can not Wrap.</p>
