title: Prevent screen scrolling up when soft keyboard is shown in WP7?
body: <p>Is there a way to prevent the screen to shift upwards when the soft keyboard is shown in a Windows Phone app? </p>
  
  <p>I have a text box which is located in the upper half of the screen, so when the soft keyboard is shown, it doesn't cover the text box. However, when the textbox is tapped, the screen still shifts up.</p>
  
  <p>Can this be prevented?</p>
