示例1: ScrollItem

{
if (control == null || control.Items == null)
return;
var scrollViewer = VisualTreeUtilities.GetVisualChild<ScrollViewer>(control);
var p = new Point(Window.Current.Bounds.Width/2, 10);
var transform = control.TransformToVisual(Window.Current.Content);
var checkPoint = transform.TransformPoint(p);
var q = from lvi in VisualTreeHelper.FindElementsInHostCoordinates(checkPoint, scrollViewer).OfType<ListViewItem>()
where lvi.Content != null
select lvi.Content;
var item = q.FirstOrDefault();
if (item == null)
return;
var index = control.Items.IndexOf(item);
var nextItemIndex = index + indexDelta;
if (index != -1 && nextItemIndex >= 0 && nextItemIndex < control.Items.Count)
{
var nextItem = control.Items[nextItemIndex];
control.ScrollIntoView(nextItem, ScrollIntoViewAlignment.Leading);
}
