C＃WinRT / Metro应用程序-ScrollViewer分页

Question

I need to implement horizontal paging functionality on ScrollViewer like in iOS. To do that I need to catch the event when ScrollViewer did ends decelerating, but ScrollViewer doesn't have that kind of events like in IOS, eg
-scrollViewDidEndDecelerating:
-scrollViewDidEndScrollingAnimation: ,etc...

Does any one know how to catch those events, or suggest a better method how to achieve paging functionality, or may be you know a 3rd party already implemented ScrollViewer with paging?

I'm not sure what paging means in iOS, but if I am guessing correctly - you might be interested in looking at HorizontalSnapPointsAlignment and HorizontalSnapPointsType properties. Or even better just use the FlipView control. The two properties will allow the ScrollViewer to automatically snap to elements of the ItemsPanel(Root) , so for example if the panel is an (Items)StackPanel - it will snap to the elements of that and thus give you the page snap behavior in a control similar to the FlipView .
