jQGrid asp.net mvc 3 implementation from scratch - asp.net-mvc-3

Question

I am trying to implement jQGrid in my application with some basic features including filtering and sub grid. I looked numerous articles but many of them seem to be old and outdated. I think i am struggling with the basics of implementing it. I will really appreciate if you can provide basic controller view structure or refer to any sort of tutorial from scratch with asp. net mvc 3.

Here is the code in the View (first mark-up, then JS):
#model SampleApp.SampleModel
#{
ViewBag.Title = "Stackoverflow Title";
Layout = "~/Views/Shared/_defaultLayout.cshtml";
}
<link href="#Url.Content("~/Content/themes/cupertino/jquery-ui-1.8.13.custom.css")" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/grid/ui.jqgrid.css")" rel="stylesheet" type="text/css" />
<script src="#Url.Content("~/Scripts/ui/jquery-ui-1.8.12.custom.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/grid/grid.locale-en.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/grid/jquery.jqGrid.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/myJSHelper.js")" type="text/javascript"></script>
<script type="text/javascript" id="loadGridResultsScript1">
// This code LOADs the grid by calling the MVC Action to get Data
$(document).ready(function () { helper.loadSearchResults('#Model.JobCode'); });
</script>
<!-- these are the jQuery Grid controls -->
<table id="list" class="scroll" cellpadding="0" cellspacing="0"></table>
<div id="pager" class="scroll" style="text-align:center;"></div>
Here is the JS function from myHelper JS file:
loadSearchResults: function (id) {
$("#list").jqGrid({
url: vpath + '/Sample/GetTargets/' + id,
datatype: 'json', mtype: 'POST', colNames: cols,
colModel: colModel, pager: $('#pager'),
rowNum: 15, rowList: [5, 10, 15, 25, 50, 100], sortname: cols[1],
sortorder: "asc", viewrecords: true,
imgpath: '', caption: ' '
});
$("#list").setGridWidth(1000, true);
$("#list").setGridHeight(350, true);
}
and here is the Action that jQuery calls:
public ActionResult GetTargets(string id, string sidx, string sord, int page, int rows)
{
var repo = IOCContainer.Resolve<DataRepository>();
////////////////////////////////////////////////////////////////////
var job = svc.GetJobByCode(id);
// job is my 'Model', it is a System.Data.DataSet
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
int totalRecords = (job.Targets == null) ? 0 : job.Tables[0].Rows.Count;
int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
List<DataRow> pageSet = Enumerable.Empty<DataRow>().ToList();
if (totalRecords > 0)
{
// Get rows for current page!!!
if (sord == "asc")
{
if (sidx == " ") sidx = job.Tables[0].Columns[0].ColumnName;
pageSet = job.Tables[0].Rows.Cast<DataRow>()
.OrderBy(q => q[sidx])
.Skip(pageIndex * pageSize)
.Take(pageSize)
.ToList();
}
else
pageSet = job.Targets.Tables[0].Rows.Cast<DataRow>()
.OrderBy(q => q[sidx])
.Reverse()
.Skip(pageIndex * pageSize)
.Take(pageSize)
.ToList();
}
var cols = GetColumnNames(job.Tables[0]);
// Func to get Cells, called later on in code...
Func<DataRow, string[], string[]> getCells = (pkg, columns) =>
{
var cellList = new List<string>();
cellList.Add(pkg[0].ToString());
foreach (var col in columns)
{
if (col.StartsWith("_")) continue;
object cellContent = pkg[col];
string cellText = string.Empty;
if (cellContent is DateTime)
{
cellText = ((DateTime)cellContent).ToString("MM/dd/yyyy");
}
else if (cellContent is decimal || cellContent is double)
{
cellText = string.Format("{0:c}", cellContent);
}
else
{
cellText = String.Format("{0}", cellContent);
}
cellList.Add(cellText);
}
return cellList.ToArray();
};
var jsonData = new
{
total = totalPages,
page,
records = totalRecords,
rows = (
from item in pageSet
select new
{
i = item[0].ToString(),
cell = getCells(item, cols)
}).ToArray()
};
return Json(jsonData);
}
I hope you find this helpful. Let me know if there are any questions
