title: Load more items on grid view scroll end
body: <p>I am developing a Windows Store Application in XAML/C# and I have a GridView displaying 12 items at a time (3 x 4). What I need to do is once the user scrolls to the end, more items are added to the GridView. How do I catch the event for scrolling at end?? I tried many approaches, but nothing worked...</p>
  
  <p><strong>UPDATE:</strong>
  It took me a LOOOONG time and lots of examples to figure what I was doing wrong. ListView worked, but GridView didn't... 
  Finally I noticed that the GridView items must have a width height in order for incremental loading to work.</p>
