WinRT gridview scroll detection

on WinRT, I have a gridview. I want to execute a method when the end of the gridview is reached.

However, there is no event method like that for a gridview.

I try to detect a manipulation of the gridview, but seems the scrollviewer included in my gridview catch all the events. How can I get this scrollviewer ? And even after, with my scrollViewer, how can i know the position of this scrollviewer (reachedEnd for example ?)

Thanks

You can use VisualTreeHelper to find a descendant of the GridView of type ScrollViewer, then subscribe to its ViewChanged event. In the event handler you can detect where you are in the ScrollViewer. You would then compare the ScrollViewer.ScrollableWidth with HorizontalOffset to see if you have reached the end.

Use it if you want to drive some custom layout/animation logic, but do use ISupportIncrementalLoading though as chue x suggested if what you are trying to do is load more data.
