title: Prevent the SIP/Soft Keyboard from popping up when a TextBox get focus
body: <p>In my Windows Phone 7 Silverlight application I have my own custom keypad that I want to use instead of the standard soft keyboard. The problem that I have is that I have not found a way to completely disable or prevent the SIP/Soft Keyboard for my application or for the TextBox component. </p>
  
  <ul>
  <li>Is it possible to disable the soft input keyboard in my application?</li>
  <li>Is it possible to prevent the soft input keyboard from popping up when a TextBox get focus?</li>
  <li>Can I extend or override any functions in TextBox to make it behave the way I want?</li>
  </ul>
  
  <p>I’ve seen solutions how to hide the keyboard when a certain key is entered by moving focus off the TextBox but I want to prevent it from ever showing up. </p>
  
  <p>My problem is very similar to what's stated on <a href="https://stackoverflow.com/questions/7665685/how-do-i-prevent-the-software-keyboard-from-popping-up">How do I prevent the software keyboard from popping up?</a> and <a href="https://stackoverflow.com/questions/8888578/how-to-prevent-keyboard-to-show-in-edittext-ontouch">How to prevent keyboard to show in EditText onTouch?</a> but for Windows Phone 7 instead. </p>
  
  <p>I am fully aware that some may think it is stupid to use your own keypad instead of the standard input but I have my reasons for doing it this way and I just want to know if it is possible to achieve what's described.</p>
