datagridview与contextmenustrip完美结合应用

上图是最佳datagridview与contextmenustrip合用效果，方法是：

而当两个以上的datagridview共同使用一个ContextMenuStrip时，【打开】【关闭】处理事件识别SourceControl的方法：

private void 打开ToolStripMenuItem_Click(object sender, EventArgs e)
{
  ContextMenuStrip cmStrip = (ContextMenuStrip)((ToolStripMenuItem)sender).Owner;
  string ctrlSrcName = cmStrip.SourceControl.Name;
  if (ctrlSrcName.Equals("dataGridView3"))
  {}
  else if (ctrlSrcName.Equals("dataGridView4"))
  {}
}

附动态右键生成contextMenuStrip的方法：

private void dataGridView4_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.Button == System.Windows.Forms.MouseButtons.Right)
    {
        if (e.RowIndex >= 0)
        {
            dataGridView4.ClearSelection();
            dataGridView4.Rows[e.RowIndex].Selected = true;
            dataGridView4.CurrentCell = dataGridView4.Rows[e.RowIndex].Cells[e.ColumnIndex];
            this.contextMenuStrip1.Tag = "dataGridView4";
            this.contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);
        }
    }
}
