ListView ScrollChanged Event

Question

Hi,

I have a ListView item in C# metro application.I need to track scroll event in it.There is no external scrollviewer used to enable UI Virtualization.With scrollviewer,we can track scrollchanged event.But unable to track the same in ListView with its in-built scroller.

There has been a lot of buzz with this question of handling scroll event in ListView over the forums but the solution involves in C++ or even C# using WndProc messages which I feel is not supported in METRO. 

Is there any suggestion to track the scroll event of ListView.

Scenario is when listview gets scrolled I need to disable a popup window.

Tried with Window.PointerWheelChanged event handler which works for mouse scroll but I need to make it work for scrolling the ListView.

Check this out for ways of accessing the ScrollViewer within a control, which should work for both GridView and ListView:

How can I get the position of scroll bar in GridView?
