jqGrid中缺少顯示數據

Question

如下所示，我有3張圖片。 (5, 10 and 20 data per page) 。 我不知道為什么10 and 20 per page的數據如所提供的圖片丟失。

碼

public JsonResult GetDPS(string sidx, string sord, int page, int rows, string startdate, string enddate, string EmployeeId, string month, string year, int ClassificationId)
    {
        var context = new Entities();
        var _pr = new Repository();
        int _month = Convert.ToInt32(month);
        int _employeeid = Convert.ToInt32(EmployeeId);
        int _year = Convert.ToInt32(year);
        if (_month > 0 && _year > 0)
        {
            DateTime Dstartdate = new DateTime(_year, _month, 1);
            startdate = Dstartdate.AddDays(-1).ToShortDateString();
            enddate = Dstartdate.AddMonths(1).ToShortDateString();
        }
        int pageIndex = Convert.ToInt32(page) - 1;
        int pageSize = rows;
        var periods = _pr.GetDPSList(Convert.ToDateTime(startdate), Convert.ToDateTime(enddate), _employeeid, ClassificationId);
        int totalRecords = periods.Count();
        int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
        var reqs = periods.OrderBy("it." + sidx + " " + sord).Skip(pageIndex * pageSize).Take(pageSize);
        int i = 0;
        var rowsObj = new object[pageSize > totalRecords ? totalRecords : pageSize];
        foreach (vwDPSPerEmployee req in reqs)
        {
            int rowId = i;
            int DPSHeaderId = Convert.ToInt32(req.DPSHeaderId);
            string DateApplied = req.DateApplied.Value.ToShortDateString();
            string DPSClassification = req.DPSClassificationDesc;
            string StartDate = req.DateFrom.Value.ToShortDateString();
            string EndDate = req.DateTo.Value.ToShortDateString();
            string Departure = req.Departure.Value.ToShortTimeString();
            string Arrival = req.Arrival.Value.ToShortTimeString();
            string Destination = req.Destination;
            string ContactPerson = req.ContactPerson;
            string Purpose = req.Purpose;
            rowsObj[i] = new { id = i, cell = new object[] { rowId, DPSHeaderId, DateApplied, DPSClassification, StartDate, EndDate, DateofDPS, Departure, Arrival, Destination, ContactPerson, Purpose } };
            i++;
        }
        if (totalRecords != 0)
        {
            for (int j = 0; j < rowsObj.Length; j++)
            {
                if (rowsObj[j] == null)
                { rowsObj[j] = new { id = j, cell = new object[] { j, j, "", "" } }; }
                else { }
            }
        }
        var result = new JsonResult();
        result.Data = new
        {
            total = totalPages,
            page = page,
            records = totalRecords,
            rows = rowsObj
        };
        return result;
    }

有沒有人遇到這樣的事情？ 還是有人知道嗎？ 我花了幾天時間來解決這個問題。

我認為您應該在Fileddate（DateApplied）列上使用排序。

public JsonResult GetDPS(string sidx, string sord, int page, int rows, string startdate, string enddate, string EmployeeId, string month, string year, int ClassificationId)
    {
        var context = new Entities();
        var _pr = new Repository();
        int _month = Convert.ToInt32(month);
        int _employeeid = Convert.ToInt32(EmployeeId);
        int _year = Convert.ToInt32(year);
        if (_month > 0 && _year > 0)
        {
            DateTime Dstartdate = new DateTime(_year, _month, 1);
            startdate = Dstartdate.AddDays(-1).ToShortDateString();
            enddate = Dstartdate.AddMonths(1).ToShortDateString();
        }
        int pageIndex = Convert.ToInt32(page) - 1;
        int pageSize = rows;
        var periods = _pr.GetDPSList(Convert.ToDateTime(startdate), Convert.ToDateTime(enddate), _employeeid, ClassificationId);
        int totalRecords = periods.Count();
        int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
        var reqs = periods.OrderBy(x=>x.DateApplied).Skip(pageIndex * pageSize).Take(pageSize);
        int i = 0;
        var rowsObj = new object[pageSize > totalRecords ? totalRecords : pageSize];
        foreach (vwDPSPerEmployee req in reqs)
        {
            int rowId = i;
            int DPSHeaderId = Convert.ToInt32(req.DPSHeaderId);
            string DateApplied = req.DateApplied.Value.ToShortDateString();
            string DPSClassification = req.DPSClassificationDesc;
            string StartDate = req.DateFrom.Value.ToShortDateString();
            string EndDate = req.DateTo.Value.ToShortDateString();
            string Departure = req.Departure.Value.ToShortTimeString();
            string Arrival = req.Arrival.Value.ToShortTimeString();
            string Destination = req.Destination;
            string ContactPerson = req.ContactPerson;
            string Purpose = req.Purpose;
            rowsObj[i] = new { id = i, cell = new object[] { rowId, DPSHeaderId, DateApplied, DPSClassification, StartDate, EndDate, DateofDPS, Departure, Arrival, Destination, ContactPerson, Purpose } };
            i++;
        }
        if (totalRecords != 0)
        {
            for (int j = 0; j < rowsObj.Length; j++)
            {
                if (rowsObj[j] == null)
                { rowsObj[j] = new { id = j, cell = new object[] { j, j, "", "" } }; }
                else { }
            }
        }
        var result = new JsonResult();
        result.Data = new
        {
            total = totalPages,
            page = page,
            records = totalRecords,
            rows = rowsObj
        };
        return result;
    }
