Mine is a MVC project. From my view am making a AJAX call to get the JSON data. From my controller when i deseralize my class using javascriptDeserializer, i get below
{
"page":1,
"total":2,
"records":2,
"rows":[
{"id":1,"cell":["ToolVersion","1","ESP","1.2","2/2/2013"]},
{"id":2,"cell":["ToolVersion","2","OPT","1.3","3/3/2013"]}
]
}
The action method as below
var lst = obj.GetDetails(); // this returns the instance of MyCustomJQGrid class.
return Json(new
{
total = 2,
page = 1,
records = 2,
rows = lst.rows.ToArray()
}, JsonRequestBehavior.AllowGet);
public class MyCustoMJQGrid
{
public class Row
{
public int id { get; set; }
public List<string> cell { get; set; }
public Row()
{
cell = new List<string>();
}
}
public int page { get; set; }
public int total { get; set; }
public int records { get; set; }
public List<Row> rows { get; set; }
public JQGrid()
{
rows = new List<Row>();
}
}
in view, am using below code
$('#list2').jqGrid({
url: '#(Url.Action("GetToolVersionDetails", "Admin"))',
datatype: 'json',
colNames: ['TableName','RowId', 'ColA', 'ColB', 'ColC'],
mtype: 'GET',
colModel: [
{ name: 'TableName', index: 'TableName', width: 150 },
{ name: 'RowId', index: 'RowId', width: 150 },
{ name: 'ColA', index: 'ColA', width: 250 },
{ name: 'ColB', index: 'ColB', width: 250 },
{ name: 'ColC', index: 'ColC', width: 250 }
],
jsonReader: {
root: 'rows',
total: 'total',
page: 'page',
records: 'records',
cell: 'cell',
id: 'id',
repeatitems: false
},
rowNum: 10,
rowList: [5, 10, 20, 30],
pager: $('#gridpager'),
sortname: 'RowId',
viewrecords: true,
sortorder: 'asc',
caption: 'Tool Version',
shrinkToFit: true,
width: $('#gridContainer').width(),
height: 200,
hidegrid: false,
});
jqgrid is getting displayed with two empty rows. no data is displayed. it just shows a blank table with two rows. JSON data is not getting displayed.
Kindly help.
Thanks.

I suggest you to install and use MvcJqGrid nuget package, to have a full featured fluent grid solution with mvc helpers.
It represents a repository class to select, filter and sort rows. It also represents a GridSettings type that you can simply use in your controller to put data rows into a json response and send it to the view.
Examples are here.
Codes for repository class are here. You also can find all other required codes there
