推荐答案

只需使用MouseUp事件来检测鼠标单击。 DataGridView.HitTest（）方法可以告诉您单击了DGV的哪一部分，从而允许您选择所需的CMS。例如：

Simply use the MouseUp event to detect the mouse click. The DataGridView.HitTest() method can tell you what part of the DGV was clicked, allowing you to pick the CMS you want. For example:

    private void dataGridView1_MouseUp(object sender, MouseEventArgs e) {
        if (e.Button != MouseButtons.Right) return;
        var dgv = (DataGridView)sender;
        ContextMenuStrip cms = null;
        var hit = dgv.HitTest(e.X, e.Y);
        switch (hit.Type) {
            case DataGridViewHitTestType.ColumnHeader: cms = contextMenuStrip1; break;
            case DataGridViewHitTestType.Cell: cms = contextMenuStrip2; break;
        }
        if (cms != null) cms.Show(dgv, e.Location);
    }
