Dev GridView 右键复制单元格内容

--先给GridView控件注册鼠标按下事件gv.MouseDown += new System.Windows.Forms.MouseEventHandler(this.gv_MouseDown);
--在鼠标按下事件里面增长鼠标右键判断，并增长鼠标右键菜单复制单元格功能。
 private void gv_MouseDown(object sender, MouseEventArgs e)
 {
            if (e.Button == MouseButtons.Right)
            {
                GridHitInfo gridHitInfo = new GridHitInfo();
                Point point = new Point(e.X, e.Y);
                gridHitInfo = (sender as GridView).CalcHitInfo(point);
                if (gridHitInfo.Column == null) return;                --获取单元格内容
                string copiedData = (sender as GridView).GetRowCellDisplayText(gridHitInfo.RowHandle, gridHitInfo.Column);
                if (string.IsNullOrEmpty(copiedData)) return;
                --复制到剪贴板
                Clipboard.Clear();
                Clipboard.SetData(DataFormats.Text, copiedData);
            }
  }
