How do you implement a lazy loading ListView in a simple way for UWP?
<p>I have read samples on the internet and some are very hard to learn.</p>

<p>I want to learn how to understand when the <code>ListView</code> is scrolling down and if more data is still available, how I can get the data from the internet while showing a ProgressRing on screen.</p>

<p>For my example, I use JSON to get data from a PHP server, and every request I get 10 items from the database.</p>

<p>If you could please provide an easy to understand sample, it would be very much appreciated.</p>
