title: Implementing endless scroll with web listview
body: <p>I am aware that the web version of listview doesn't have an out of the box endless scroll feature like the mobile one does. I still need to implement this in my solution and I'm not really sure where to start. All the ides I have would require me to reaload all the data again. So lets say I have 25 rows loaded. You reach the scroll point and it loads 25 more, the way I would implement it it would reload the first 25 and add 25 more. This would of course get slow the more down you go so it's not an option Ha anybody done something like this successfully? Are there any good open source endless scroll solutions available? Any tips / info / code would be appreciated.</p>
  
  <p>Thanks!</p>
