jgGrid not displaying json data - json

Question

This is driving me crazy, so any help would be awesome:
My html is as follow:
<asp:Content ID="Content3" ContentPlaceHolderID="Content" runat="server" class="MainLoginScreen">
<table id="StudyTable"></table>
<div id="StudiesPager"></div>
</asp:Content>
My javascript is as follows:
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("#StudyTable").jqGrid({
url: '/StudyManager/GetStudyTable.aspx',
datatype: "json",
mtype:"GET",
colNames: ['Name', 'URL', 'Creation Date', 'Description', 'Status'],
colModel:[
{ name: 'Name', width: 200},
{ name: 'URL', width: 100 },
{ name: 'Creation_Date', width: 300},
{ name: 'Description', width: 200 },
{ name: 'Status', width: 200}
],
rowNum:10,
rowList:[10,20,30],
viewrecords: true,
sortname: 'Name',
sortorder: "asc",
pager: $('#StudiesPager'),
imgpath: '/Content/Images',
jsonReader: {
root: "rows",
page: "page",
total: "total",
records: "records",
repeatitems: true,
cell: "cell",
id: "id"
},
width: 800,
height: 400
});
});
</script>
and my cs code is:
protected void Page_Load(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.Append("{'total':1,");
sb.Append("'page':'1',");
sb.Append("'records':'1',");
sb.Append("'rows': [");
sb.Append("{ 'id':'123', 'cell':['abc','abc','abc','abc','abc']}");
sb.Append("]}");
Response.Clear();
Response.StatusCode = 200;
Response.Write(sb.ToString());
Response.End();
}
The table and pager are displayed perfectly, but no data is rendered to the table.
The returned json from my cs seems to be in the correct format:
{'total':1,'page':'1','records':'1','rows': [{ 'id':'123', 'cell'['abc','abc','abc','abc','abc']}]}
But no data is being displayed in the grid.

Answer 1

Also you can create something like:
public class JqGridJsonData
{
public int Total {get;set;}
public int Page {get;set;}
etc
}
And serialize this to json with Json.NET

Answer 2

Of all things that could cause the problem - it was the single quotations. JSON doesnt seem to allow 'word', but rather needs \"word\".
So the output json from the cs should have been :
{"total":"1","page":"1","records":"1","rows": [{ "id":"123", "cell"["abc","abc","abc","abc","abc"]}]}
