Telerik UI for Windows Phone by Progress

RadLoopingList exposes two very simple events. These are SelectedIndexChanged and ScrollCompleted.

ScrollCompleted is fired when the scrolling animation finishes. It is important to note that snapping also triggers this event.

SelectedIndexChanged on the other hand fires when the user selects an item, when the SelectedIndex property of RadLoopingList is set

through code and when the item is automatically centered and selected by the snapping feature.
