The "Scrolled" event is such a essential feature.

For example, i made a floating searchbar with transparent frame, and a RadListView with HeaderTemplate that is longer than a screen of the device, i would like to detect whether the listview has scrolled for more than 10px vertically. If yes, set the background of the frame of the searchbar to my desired color.Xamarin.Forms, collectionview, listview, and scrollview has Scrolled event, but why RadListView does not? Using ItemAppearing event is just avoiding the problem instead of solving it. It will not be able to fulfill the criteria as the any item does not even enter the screen yet before the required task need to be done.
