title: Message Box with Yes and No buttons
body: <p>I am working on Windows Phone 8, i have scenario where in the message box i am questioning the  user, So the user has to click YES or NO.</p>
  
  <p>But the meassage box is having only OK and Cancel buttons, which i dont need it.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>MessageBoxResult m = MessageBox.Show("Are you sure? This will delete all your data", "Attention!", MessageBoxButton.OKCancel);
              if (m == MessageBoxResult.Cancel)
              {
  
              }
              else
              {
                  MessageBox.Show("Data Deleted", "Done", MessageBoxButton.OK);
              } 
  </code></pre>
  
  <p>How can i modify this to YES and NO buttons ? and also can i have 3 buttons as well with custom text on buttons? </p>
