Not able to Add row using JQGrid - asp.net

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
{
id = tm.colID,
cell = new string[] { tm.colID.ToString(), tm.FirstName, tm.LastName }
}).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);
}
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Remove(string id)
{
List<String> ids = new List<String>(id.Split(','));
for (int i = 0; i < ids.Count; i++)
{
int deleteid = Convert.ToInt32(ids[i]);
TabMasterViewModel deleteExisting = new TabMasterViewModel();
deleteExisting = _tabmasterService.GetSingle(x => x.colID == deleteid);
_tabmasterService.Delete(deleteExisting);
}
return RedirectToAction("Index");
}
#endregion
Note:- Get and Update is successfully working but i have problem in ADD and DELETE.
