title: How to get raw text from MaskedTextBox?
body: <p>I have a MaskedTextBox with this mask (999) 999 9999.
  When user inputs a number the text property would give this to me :</p>
  
  <pre><code>(0881) 444 5445
  </code></pre>
  
  <p>But I want to save the raw text to database field like this: <code>08814445445</code>.
  How can I do that?</p>
