拖一个ContextMenuScript出来，设好你的右键菜单，把DataGridView的ContextMenuScript属性设为该菜单ID，设一下SelectionMode

            if (e.Button == MouseButtons.Right)
            {
                DataGridView.HitTestInfo hit = this.dataGridView1.HitTest(e.X, e.Y);
                if (hit.Type == DataGridViewHitTestType.Cell)
                {
                    this.dataGridView1.Rows[hit.RowIndex].Selected = true;
                    this.contextMenuStrip1.Show(this.dataGridView1, e.X, e.Y);
                }
            }
