WEBContainer scrolling event

Is there a way to know when a WEBContainer has bean scrolled ?

I am trying to implement lazy loading things, but I need to know when a container has been scrolled so I can check where it has been scrolled to see if it is time to load more content?

Any idea would help! Even hacking…

There is a ContentsScrolled event introduced in 2013r1.

Darn it!! How can I have missed it!

Is there a Property to see where the scroll is?

Never mind… Just saw the docs!!

Is it possible to prevent this event from firing? Because I see a lot of POST request sent bach to the server during a scroll that makes things run a little slowly.
