How can I detect reaching the end of a ScrollViewer item (Windows 8)?

问题

I need to do some work when the user scrolls to the end of a ScrollViewer in a Windows 8 'Metro UI' app that uses .xaml with C# behind-code. Alternatively, the ScrollViewer has snap-points enabled, so detecting a "snapping" event will also work.

Thanks

You can bind your ListView to collection that implements ISupportIncrementalLoading.

The extra items will be loaded automatically when there is an empty space to fill.

I'm not sure it works when getting back from snapped-mode, haven't tried it yet.

Not Windows 8 exactly, but still XAML.
