if ((index != -1) && (list.layout != null)) {
var spDelta:Point = list.dataGroup.layout.getScrollPositionDeltaToElement(index);
if ((spDelta != null) && (spDelta.y != 0)) {
var target:DataGroup = list.dataGroup;
var animation:AnimateProperty = new AnimateProperty(target);
animation.property = "verticalScrollPosition";
animation.duration = animationDuration;
animation.toValue = target.verticalScrollPosition + spDelta.y;
animation.play();
