title: Flip a FlipView
body: <p>I have a FlipView (xaml) with ItemsSource binding on a list of periods (months). The periods are dynamically added to the list: when you go to the next period, the next period (of that next period) will be added to the list.</p>
  
  <p>So if you have a list like this:</p>
  
  <pre><code>[October 2013, November 2013, December 2013, January 2014, February 2014, March 2014]
  </code></pre>
  
  <p>When you are on February 2014 and you press next, you'll go to March 2014 and April 2014 will be added to the list.</p>
  
  <p>But I want to flip the FlipView, so that when you press (or swipe) back (to the left) it will go to the next index instead of the previous.</p>
  
  <p>It's very difficult to explain, because English is not my native language. I hope you understand the problem...</p>
