title: Windows phone 7 Handling backspace KeyDown event
body: <p>I have a textbox in XAML:</p>
  
  <pre><code>&lt;TextBox Text="blah" 
           Name="blah" 
           LostFocus="blah_OnLostFocus" 
           KeyDown="blah_OnKeyDown"/&gt;
  </code></pre>
  
  <p>.cs file has the following event declared:</p>
  
  <pre><code>    private void blah_OnKeyDown(object sender, KeyEventArgs e)
      {
          TextBox t = sender as TextBox;
          int i = 0;
          if(e.Key == Key.Delete)
              i = 1;
      }
  </code></pre>
  
  <p>When I press the backspace key on the emulator's keyboard, the event is ignored. If I press any other button, it is triggered. Also, when I use the same event body for the KeyUp event, backspace key triggers it.</p>
  
  <p>How do I track when the backspace key was pressed for KeyDown event? Why is pressing the backspace key does not trigger the KeyDown event?</p>
  
  <p>Thank you.</p>
