Question

Here is the JQGrid setup information

jQuery(document).ready(function () {
    jQuery("#list").jqGrid({
        url: '/TabMaster/GetGridData',
        datatype: 'json',
        mtype: 'GET',
        colNames: ['col ID', 'First Name', 'Last Name'],
        colModel: [
              { name: 'colID', index: 'colID', width: 100, align: 'left' },
              { name: 'FirstName', index: 'FirstName', width: 150, align: 'left', editable: true },
              { name: 'LastName', index: 'LastName', width: 300, align: 'left', editable: true },
            ],
        pager: jQuery('#pager'),
        rowNum: 4,
        rowList: [1, 2, 4, 5, 10],
        sortname: 'colID',
        sortorder: "asc",
        viewrecords: true,
        multiselect: true,
        imgpath: '/scripts/themes/steel/images',
        caption: 'Tab Master Information'
    }).navGrid('#pager', { edit: true, add: true, del: true },
    // Edit options
           {
           savekey: [true, 13],
           reloadAfterSubmit: true,
           jqModal: false,
           closeOnEscape: true,
           closeAfterEdit: true,
           url: "/TabMaster/Edit/",
           afterSubmit: function (response, postdata) {
               if (response.responseText == "Success") {
                   jQuery("#success").show();
                   jQuery("#success").html("Company successfully updated");
                   jQuery("#success").fadeOut(6000);
                   return [true, response.responseText]
               }
               else {
                   return [false, response.responseText]
               }
           }
       },
    // Add options
           {},
    // Delete options
           {url: '/TabMaster/Remove' }
           );
});

following is the details for Getting Data and Update Data using JQGrid

#region "JQGrid Actions"
            public JsonResult GetGridData(string sidx, string sord, int rows, int page)
            {
                int pageIndex = page;
                int totalRecords = Convert.ToInt32(_tabmasterService.Count());
                int totalPages = (int)Math.Ceiling((float)totalRecords / (float)rows);
                IQueryable<TabMasterViewModel> tabmasters = _tabmasterService.GetQueryTabMasterList(sidx, sord, rows, page);
                var jsonData = new

                    total = totalPages,
                    page = page,
                    records = totalRecords,
                    rows = (from tm in tabmasters
                            select new

                            }).ToArray()
                };
                return Json(jsonData, JsonRequestBehavior.AllowGet);
            }
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Edit(int id, FormCollection updateExisting)
            {
                int _id = Convert.ToInt32(updateExisting["colID"]);
                TabMasterViewModel editExisting = new TabMasterViewModel();
                editExisting = _tabmasterService.GetSingle(x => x.colID == id);
                try
                {
                    UpdateModel(editExisting);
                    _tabmasterService.Update(editExisting);
                    return Content("Success");
                }
                catch (Exception e)
                {
                    return Content(e.Message);
                }
