当然可以实现
1. treeView2.AllowDrop = true;//允许拖放操作
DataGridView.AllowDrop=true;

2. 下列各事件分别处理(树,表格同)



        private void treeView1_DragEnter(object sender, DragEventArgs e)

        {

            e.Effect = DragDropEffects.Move;

        }



        private void treeView1_DragDrop(object sender, DragEventArgs e)

        {

            Point pt = this.treeView1.PointToClient(new Point(e.X, e.Y));

            TreeNode tagNode = this.treeView1.GetNodeAt(pt);

            TreeNode sourNode = (TreeNode)e.Data.GetData(typeof(TreeNode));



            this.treeView1.Nodes.Remove(sourNode);

            tagNode.Nodes.Add(sourNode);

        }



        private void treeView1_ItemDrag(object sender, ItemDragEventArgs e)

        {

            if (e.Button == MouseButtons.Left)

            {

                this.treeView1.DoDragDrop(e.Item, DragDropEffects.Move);

            }

        }
