Hello

Hello

将scatterview移出屏幕您可以在scatterwiew的中心使用动画。通过检查散点图中心位置何时触及屏幕的边缘，您可以使用以下方法将其从屏幕中删除：

to move scatterview out of the screen you can use an animation on the Center of the scatterwiew. By checking when the scatterview center position is hitting the edg of the screen, you can use the follwing method to remove them from screen:

public static void TranslateBeforeRemove(ObservableCollection<ScatterViewItem> Collection, ScatterViewItem svi)        {            Point RemovePoint = new Point(svi.ActualCenter.X + (1920 - svi.ActualCenter.X) + 800, svi.ActualCenter.Y);            PointAnimation CenterAnimation = new PointAnimation(svi.ActualCenter, RemovePoint, TimeSpan.FromSeconds(1), FillBehavior.Stop);            CenterAnimation.AccelerationRatio = 0.5;            CenterAnimation.DecelerationRatio = 0.0;            CenterAnimation.FillBehavior = FillBehavior.Stop;            CenterAnimation.Completed += delegate(object send, EventArgs ev)            {                Collection.Remove(svi);            };            svi.IsEnabled = false;            svi.BeginAnimation(ScatterViewItem.CenterProperty, CenterAnimation);        }
