Subgrid not getting populated in free jqGrid

I am trying to add subgrid to every row of main grid. The main grid populates fine but when i click on the expand icon of a row subgrid is not populated. Only subgrid column headers appear.
The json data is a single nested data structure which is fetched only once when grid loads first time. So when i click on the grid expand icon i expect subgrid to be populated from the data that was fetched while displaying the parent grid.
The empty subgrid is displayed when i use - datatype: "local".
If i set datatype: "json" then a server side call is made to fetch data if i click on expand icon.
So how can i display subgrid using the single json data that was already fetched. Thanks
Please find sample code below,
$(document).ready(function () {
"use strict";
var dataGrid = $('#itemList');
var firstClick = true;
$('#action').click(function () {
if (!firstClick) {
$("#itemList").setGridParam({datatype:'json'}).trigger("reloadGrid");
}
firstClick = false;
$("#itemList").jqGrid({
url: "${pageContext.request.contextPath}/billing/items",
datatype: "json",
mtype: "POST",
autowidth: true,
loadBeforeSend: function(jqXHR) {
jqXHR.setRequestHeader("X-CSRF-TOKEN", $("input[name='_csrf']").val());
},
colNames: ["Id", "Item Type", "Item Code"],
colModel: [
{ name: "id", width: 35, sorttype:"int", search: false, editable: false, key: true, hidden: true},
{ name: "itemType", width: 100},
{ name: "itemCode", width: 120}
],
maxHeight: 400,
cmTemplate: {editable: true},
pager: true,
rowNum: 50,
rowList: [50, 100, 150, 200],
rownumbers: true,
rownumWidth: 25,
sortname: "itemType",
sortorder: "asc",
forceClientSorting: true,
viewrecords: true,
height: '100%',
loadonce: true,
//gridview: true,
autoencode: true,
editurl: "${pageContext.request.contextPath}/billing/saveItem",
caption: "Item List",
subGrid: true,
subGridRowExpanded: function (subgridId, rowid) {
var subgridTableId = subgridId + "_t";
$("#" + subgridId).html("<table id='" + subgridTableId + "'></table>");
$("#" + subgridTableId).jqGrid({
datatype: "local",
data: $(this).jqGrid("getLocalRow", rowid).itemDetails,
colNames: ["Id", "Unit", "Stock", "Batch No.", "Expiry Date", "Quantity Per Unit", "Price"],
colModel: [
{ name: "id", width: 35, sorttype:"int", search: false, editable: false, key: true, hidden: true},
{ name: "unit", width: 70, search: false},
{ name: "availableQuantity", width: 55, search: false, formatter: "number",},
{ name: "batchNumber", width: 80, search: false},
{ name: "expiryDate", width: 80, search: false, sorttype: "date", formatoptions: {srcformat:'d/m/Y', newformat:'d/m/Y'}},
{ name: "quantityPerUnit", width: 80, search: false, formatter: "number"},
{ name: "price", width: 55, search: false, formatter: "number"}
],
height: "100%",
rowNum: 10,
idPrefix: "s_" + rowid + "_",
cmTemplate: {editable: true},
editurl: "${pageContext.request.contextPath}/billing/saveItem"
});
}
}).navGrid({add:false,edit:false,del:true});
$("#itemList").jqGrid('filterToolbar', {autoSearch: true, stringResult: true, searchOnEnter: false, defaultSearch: 'cn'});
$("#itemList").jqGrid('gridResize', { minWidth: 450, minHeight: 150 });
});
The sample json data:-
[{"id":1,"itemCode":"Omez","itemType":"Medicine","itemDesc":"Omez for acidity","itemDetails":[{"id":1,"batchNumber":"batch1","expiryDate":"01/06/2018","unit":"bottle","subUnit":"tablet","availableQuantity":120.0,"quantityPerUnit":60.0,"price":122.0}]}]

First of all it's important to understand that the data, returned from url will be read and saved locally in case of usage loadonce: true option of jqGrid. By default it read only the data for the columns of the grid and the property id (can be configured by id property of prmNames parameter). Free jqGrid allows to read and save any other additional properties. To specify the properties one can use additionalProperties. The simplest for of the usage would be
additionalProperties: ["itemDetails"]
It informs jqGrid to read and save locally itemDetails property of every item. After that $(this).jqGrid("getLocalRow", rowid).itemDetails will work.
Additionally you can remove the column id from colModel. jqGrid set id attribute of the rows based on the value of id property of input data (returned from the server). Thus you don't need to hold the duplicate information in hidden <td> cell of every row. You can remove the id column from both main grid and the subgrid.
If you want to set search: false for all columns of subgrid then you can use cmTemplate: {search: false} option of subgrid and remove search: false from all columns. In the same way you can include in cmTemplate the property width: 80 (cmTemplate: {search: false, width: 80}) to change the default value 150 for the width property to 80. After that you can remove width: 80 from tree columns of subdrid too.
You can remove sortorder: "asc" and height: '100%' properties, because there are default for free jqGrid. You can use
searching: {
stringResult: true,
searchOnEnter: false,
defaultSearch: 'cn'
}
The property autosearch: true (not autoSearch: true) are default. After that you can use filterToolbar without additional parameters.
I would recommend you to use additional option of navGrid: reloadGridOptions: { fromServer: true } which informs to reload the data from the server (by restoring original value of datatype) if the user clicks on Refresh button of navigator bar.

How to get all row ids of jqgrid by class

I want to get all row ids by use of row css class of a jqgrid in a method called in gridcomplete.But it is only returning rows of current page.
I want to get all row ids present in the jqgrid.
Below is my code.
function GetAllCompanyProducts(productData) {
/// <summary>method to load the Proposal grid</summary>
//Load the grid
var tabelWidth = $("#tblCompanyProducts").width();
jQuery("#tblCompanyProducts").jqGrid({
datatype: 'local',
data: productData,
jsonReader: { repeatitems: false },
loadui: "block",
autowidth: true,
mtype: 'get',
rowNum: 30,
rowList: [30, 100, 200],
viewrecords: true,
colNames: ['ProductId', 'ProductName', 'Price'],
colModel: [
{ name: 'ProductId', index: 'ProductId', width: '30%' },
{ name: 'ProductName', index: 'ProductName', width: '30%' },
{ name: 'Price', index: 'Price', width: '30%' }
],
sortname: 'ProductId',
sortorder: 'asc',
caption: "Product List",
width: tabelWidth - 10,
pager: '#divPager',
height: "100%",
hoverrows: true,
onPaging: function () {
$("#tblCompanyProducts").trigger('reloadGrid');
},
});
$("#tblCompanyProducts").jqGrid('setGridParam', { gridComplete: MakeGridRowsDraggable($("#" + this.id)) });
}
function MakeGridRowsDraggable(grid) {
/// <summary></summary>
/// <param name="grid" type=""></param>
//$("#tblCompanyProducts").val(new Date().getTime());
var searchResultsRows = $("#tblCompanyProducts .ui-row-ltr");
}
The above code returning only the rows set in the first page.
Can anybody help me on this..

Issue while loading the data in jqgrid

I'm developing a asp.net application using twitter bootstrap.
I'm trying create a jqgrid.
While loading the data im facing issues. I'm getting an error XML Parsing Error: no element found Location: moz-nullprincipal:....
Here is my code
$(document).ready(function () {
jQuery("#grid-container").jqGrid({
url: "test.url",
datatype: 'json',
mtype: 'POST',
colNames: ['Id', 'Text', 'Name'],
colModel: [
{ name: 'Id', index: 'Id', hidden: false, editable: true },
{ name: 'Text', index: 'Text', hidden: false, editable: true },
{ name: 'Name', index: 'Name', hidden: false, editable: true }
],
jsonReader: {
id: 'Id',
repeatitems: false
},
height: "100%",
pager: '#grid-pager',
rowNum: 10,
rowList: [10, 20, 30],
sortname: 'Id',
sortorder: 'desc',
viewrecords: true,
caption: "Risk Register",
loadComplete: function () {
var table = this;
}
});
});
I found that data from dal is not converting into json type.. I'm not getting the response while debugging.
Please help me out.

Why does jqGrid refuses to call it's Ajax Call more than once using the OnSelectRow Event

I have a problem with my two jqGrid grids. First I have one grid with some data that works just fine. It has an loadComplete event which sets the first row as selected. This is so that the second jqGrid gets populated based on the selected row (id) on the first jqGrid.
I have an onSelectRow event on the first grid which calls a function which contains the $('#grid).jqGrid() call of the second grid. This second grid has en url which links to a method in a controller which gets some data from a database.
This works all fine for the first selectrow (which happends automatically after the loadComplete).
My problem is that the second jqGrid doesnt repopulate after I select a different row. The programm never gets to the method in the controller (I tested with some logging). I'm really stuck at this since it works for the first load but not the second and so on.
$("#fontsgrid").jqGrid({
url: 'getfonts',
mtype: "post",
datatype: "json",
sortable: true,

loadComplete: function () {

},
onSelectRow: function (id) {
loadInstallGridFonts(id);
}
}).navGrid('#pager', {edit: false, add: false, del: false});
function loadInstallGridFonts($fontid) {
$('#installGridFonts').jqGrid({

{ name: "date_installed", index: "date_installed", width: 80, sortable: true, sorttype: "date", formatter: "date", formatoptions: { newformat: 'Y-m-d' }},

pager: $('#pagerInstall')
}).navGrid('#pagerInstall', {edit: false, add: false, del: false});
}
'getfonts' and 'getinstallations' are both aliases for a controller/method used in routing (codeIgniter).
The problem is that the programm only goes to the method behind the 'getinstallations' once and not after a new rowselect.

I see many problems in your code. First of all it's important to understand that the code like
$('#installGridFonts').jqGrid({
...
});
create the grid. It means that it convert <table> element, which you placed initially on the page, to relatively complex structure of divs and tables (see here for examples). The consequence of it: you can make such call only once. If you try to create the same grid at the second time jqGrid verify that the grid already exist and do nothing. It's exactly what you can see.
One more important thing is the following: jqGrid creates the structure of divs and tables which represent the grid once, but it can fill the body of the grid (the data inside of the grid) multiple times. If you need to fill the grid with the data returned from the server you should just set parameters of the grid (url, datatype, postData and so on) and then make $("#installGridFonts").trigger("reloadGrid"). The reloading means executing new request to the server and loading the data in the the grid.
So the code could be about the following:
// we will use navGrid below more as once without editing buttons
// so we change defaults of navGrid with the folling settings
$.extend($.jgrid.nav, {edit: false, add: false, del: false});
// creates the second grid. because we don't want to make any request
// to the server at the time we will use datatype: "local"
$("#installGridFonts").jqGrid({
datatype: "local",
...
}).jqGrid("navGrid", "#pagerInstall");
// create the first grid
$("#fontsgrid").jqGrid({
...
onSelectRow: function (rowid) {
$("#installGridFonts").jqGrid("setGridParam", {
datatype: "json",
postData: {fontid: rowid}
}).trigger("reloadGrid");
}
}).jqGrid("navGrid", "#pager");
If it's required you can hide the second grid directly after creating and show it inside of onSelectRow callback.

jqGrid does not display search button

I'm using a jqGrid to display my data, but it does not display the search button. Why is that? Code is below.
$("#grdOpenItems").jqGrid({
url: 'api/matchingservicewebapi/GetAllMatchItemForClient',
datatype: 'json',
mtype: 'GET',
caption: 'Open Items',
jsonReader: { root: "rows", repeatitems: false, id : "0"},
colNames: ['Id', 'Account', 'Amount', 'Ref'],
colModel: [
{ name: 'Amount', index: 'Amount', width: 200 },
{ name: 'Account', index: 'Account', width: 300 },
{ name: 'Amount', index: 'Amount', width: 300 },
{ name: 'Ref', index: 'Ref', width: 300 }
],
rowNum: 5,
rowList: [5, 10, 15],
multiselect: true,
pager: '#pagerOpenItems',
viewrecoreds: true,
sortname: 'Id',
sortorder: "desc",
imgpath: 'Themes/images'
}).navGrid(pager, {
edit: true, add: true, del: true, refresh: true, search: true,
searchtext: "Search" });
But it displays the page navigation buttons with images, but not the search and reload button.

One problem:
viewrecoreds: true
should be
viewrecords: true
I don't believe the searching functionality in jqGrid is magical, meaning you have to wire up actual search code. Take a look at the documentation for search.
