title: how to programatically open and close bottomappbar using a eventhandler that exist in a usercontrol back code?
body: <p>I have a Windows 8 application (Xaml and C#):</p>
  
  <p>I have a userControl that is included in a MainPage.</p>
  
  <p>In this MainPage i have included a BottomAppBar that is fully functioning on RightClick and Windows+Z.</p>
  
  <p>What i need to do is to open the BottomAppBar from an event handler (in the usercontrol back code) on an image that exists in the userControl. i need to access the BottomAppBar in order to use the property IsOpen, but i am not being able to do so. Any hint? am i missing anything?</p>
