ASP.NET MVC3数据未加载到JQGrid

Question

这是我的控制器方法

    public ActionResult GridData(string sidx, string sord, int page, int rows)
    {
                var jsonData = new
                {
                    total = 1, //todo: calculate
                    page = page,
                    records = db.Employees.Count(),
                    rows = (
                      from E in db.Employees
                      select new
                      {
                          id = E.EmployeeID,
                          cell = new string[] { 
              E.EmployeeID.ToString(), E.LastName,E.FirstName,E.Title,E.TitleOfCourtesy,E.BirthDate.ToString(),E.HireDate.ToString(),E.Address,E.City,E.Region,E.PostalCode,E.Country, E.Extension,E.Notes,E.ReportsTo.ToString()

                      }
                  }).ToArray()
              };
              return Json(jsonData, JsonRequestBehavior.AllowGet);
    } 

这是我的观看代码。

    ViewBag.Title = "Index";
