    jQuery(document).ready(function () {
        jQuery("#list").jqGrid({

        });
     });
      jQuery("#list").jqGrid('navGrid', '#pager', { edit: false, add: false, del: false });
       </script>

控制器：

public ActionResult GridData(string sidx = "", string sord = "", int page = 1, int rows = 10)
    {
        TestGridModel tstGrid = new TestGridModel();
        tstGrid.listArr = new List<CommodityReport>();
        string conn = ConfigurationManager.ConnectionStrings["DbConnnectionString"].ConnectionString;
        ReportDAL rptDal = new ReportDAL();
        DataTable dt = rptDal.GetCommodity(conn, "");
        //List<string[]> row = new List<string[]>();
        List<Cell> row = new List<Cell>();
        int i = 0;
        foreach (DataRow item in dt.Rows)
        {
            row.Add(new Cell { cell = dt.Rows[i].ItemArray.Select(x => x.ToString()).ToArray() });
            i++;
        }
        var jsonData = new
        {
            total = 1, // we'll implement later 
            page = page,
            records = 3, // implement later 
            rows = row.ToArray()

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

结果：

问题是当我的控制器返回Json时，它只是在网页而不是网格上显示Json。可以帮我解决这个问题吗？
