1、設定 GirdViewt.OptionsBehavior.Editable = false;
設定變數 DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hInfo = new DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo(); //獲取“撞擊點”的位置
2、註冊GridView的滑鼠單擊及GridView的雙擊事件
this.gridView.MouseDown += new MouseEventHandler(gridView_MouseDown); //用於獲取GridHitInfo-撞擊點的資訊
this.gridView.DoubleClick += new EventHandler(gridView_DoubleClick);//雙擊事件
3、程式碼
//滑鼠單擊事件

        //獲取滑鼠點選的位置
        void gridView_InpatientPatient_MouseDown(object sender, MouseEventArgs e)
        {
            hInfo = gridView_InpatientPatient.CalcHitInfo(e.X, e.Y); 
        }

//介面雙擊的事件

        //雙擊事件
        void gridView_DoubleClick(object sender, EventArgs e)
        {
        //獲取點
            if
 
 (gridView.FocusedRowHandle < 0) return;
            try
            {
                //雙擊某一單元格，執行程式碼  
                if (hInfo.InRowCell)
                {
                    //獲取
                    int rowid = this.gridView.FocusedRowHandle;

                    string selectedStr = this.gridView.GetRowCellValue(rowid, "PatientID"
 
).ToString();

                    MessageBox.Show(selectedStr);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }  
        }
