     private void WrapPanel_Drop(object sender, DragEventArgs e)




        {



      



            var item = e.Data;



            object data = item.GetData(item.GetFormats()[0]);



            if (data is UIElement) 



            {



                send.Children.Remove(data as UIElement);



                accept.Children.Add(data as UIElement);



            }



        



        }



 



        private void WrapPanel_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)




        {



            object item = e.Source;



            if (item is UIElement) 



            {



                DragDrop.DoDragDrop(item as UIElement, item, DragDropEffects.Move);



            }



        }

accept 一方的控件 需要加上  AllowDrop="True" 允许接收drop的数据
