單純的去找雙擊確實不好實現，就用以下的方式來實現了：

  //實現雙擊開啟功能
        private void gridView1_MouseDown(object sender, MouseEventArgs e)
        {
            GridHitInfo hInfo = gridView1.CalcHitInfo(new Point(e.X, e.Y));
            //雙擊功能
            if (e.Button == MouseButtons.Left && e.Clicks == 2)
            {
                //獲取當前選中的專案，若沒有給出提示
                if (string.IsNullOrEmpty(m_sSelProjNum)) return;
                frm2NewPrj frm = null;
                if (m_bEdit)
                    frm = new frm2NewPrj(ProjEditWidowOpenMode.OPENMODE_EDIT, m_sSelProjNum, m_sSelProjName, this);
                else
                    frm = new frm2NewPrj(ProjEditWidowOpenMode.OPENMODE_QUERY, m_sSelProjNum, m_sSelProjName, this);
                frm.ShowDialog();
                frm.Dispose();
            }

        }

即呼叫的是MouseDown事件，具體的邏輯具體實現就行了
