title: How to blackout future dates
body: <p>I am trying to blackout future dates from the datepicker. I am using Silverlight for Windows Phone Toolkit for datepicker. </p>
  
  <p>the code I am trying is </p>
  
  <pre><code>DatePicker.DisplayDateEnd = DateTime.Now;
  </code></pre>
  
  <p>It gives an error that <code>Microsoft.Phone.Controls.DatePicker</code> does not contain a definition for <code>DisplayDateEnd</code>.
  Any Ideas, how to blackout or make the future date unselectable? </p>
