有谁知道Toolkit:PanelDragDropTarget怎么用么

[fanshaoer]

        private UIElement dragedob;
        private void DragLayout_ItemDragStarting(object sender, ItemDragEventArgs e)
        {
            this.TreePanel.Children.Remove(sender as UIElement);
            dragedob = sender as UIElement;
            
        }

        private void DragLayout_ItemDroppedOnTarget(object sender, ItemDragEventArgs e)
        {
            this.TreePanel.UpdateLayout();
            this.Destinetionpanel.Children.Add(dragedob);//
            //e.RemoveDataFromDragSource();
        }
