title: Expanding the size of ListView cell on tap
body: <p>I'm trying to implement a solution to increase the size of a <code>ListView</code> <code>Cell</code> when tapped using <code>Xamarin Forms</code> (and custom renderers if required).</p>
  
  <p>I'm still pretty new to C#, and the idea of data binding is still a little unclear to me, however, it seems like that is the way to go to solve this problem (perhaps something along the lines of binding the <code>Height</code> / <code>HeightRequest</code> properties of the cell?).</p>
  
  <p>My attempts thus far have been unsuccessful.</p>
  
  <p>If anyone could give me a push in the right direction it would be much appreciated. </p>
  
  <p>Thank you!</p>
