Thank you for contacting us! Currently, there is not such event exposed. I have added this as feature request in our feedback portal where you can vote for it and track its progress - http://feedback.telerik.com/Project/167/Feedback/Details/185832-radlistview-expose-viewchanged-event
I have also update your telerik points accordingly.
Currently, you can track this event by finding the nested ScrollViewer element inside the ListView and attaching to its ViewChanged event.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
