jqgrid : Inline checkbox editing in Client Side

I am using jqgrid. I want to allow people to use a checkbox in inline editing. There will not be any buttons like edit etc, As soon as he clicks the checkbox, it should be considered as committed on client side.
There is a checkbox which I want to always keep in edit mode. After user is done making changes, he will click on a submit button & full grid data will get posted to the server.
I expect that getGridParam method should give me the updated cell values. However it is not doing so.
I feel my problem is the onSelectRow method. somewhere I am missing the implementation to save the current row state. & hence in the getGridParam method. I am getting the original values.
Code :
var lastsel;
jQuery("#AcOpenDataGrid").jqGrid({
url: '/Admin/Role/GetMappedMenus',
viewrecords: true, sortname: 'Code', sortorder: "desc",
colNames: [
"Code",
"MenuName",
"Allow"
],
colModel: [
{ name: 'Code', width: 10, key: true, align: 'center', hidden: true },
{ name: 'MenuName', index: 'MenuName', width: 60, search: true, searchoptions: JQ_sopt_string, align: 'left' },
{ name: 'Allow', index: 'Allow', width: 30, editable: true,edittype:'checkbox',editoptions: { value:"True:False" },formatter:'checkbox', formatoptions: {disabled : false} ,search: true, searchoptions: JQ_sopt_string, align: 'center' },
],
height: '500',
autowidth: true,
rowList: JQ_Paging_Opt,
rowNum: JQ_RowNum_Opt,
pager: pager_selector,
datatype: 'json', mtype: 'GET',
cmTemplate: { title: false },
loadonce:true,
altRows: true,
jsonReader: { root: "rows", page: "page", total: "total", records: "records", repeatitems: false, userdata: "userdata", id: "Code" },
editurl: 'clientArray',
onSelectRow: function (id) {
if (id && id !== lastsel) {
jQuery(grid_selector).jqGrid('restoreRow', lastsel);
//jQuery(grid_selector).jqGrid('saveRow', lastsel);
jQuery(grid_selector).jqGrid('editRow', id, true);
lastsel = id;
}
},
}).navGrid(pager_selector, { view: false, del: false, add: false, edit: false, search: false, refresh: true }
).jqGrid('filterToolbar', { stringResult: true, searchOnEnter: false, defaultSearch: 'cn' });
});
$(".submit").click(function () {
var localGridData = $("#AcOpenDataGrid").jqGrid('getGridParam', 'data');
//To Do : Post Ajax here.
});

I found a solution here. Not exactly what I expected but it does serves my purpose.
Make a column be a checkbox
beforeSelectRow: function (rowid, e) {
var $self = $(this),
iCol = $.jgrid.getCellIndex($(e.target).closest("td")[0]),
cm = $self.jqGrid("getGridParam", "colModel"),
localData = $self.jqGrid("getLocalRow", rowid);
if (cm[iCol].name === "closed") {
localData.closed = $(e.target).is(":checked");
}
return true; // allow selection
},

JQGrid Does Not Return Large Set Of Data From Server

When I use jqgrid and want to render more than 5000 records in grid, no response body is returned from server which is very strange. I have Stored Procedure which returns 15000 records from database. Then from backend C# code I call this procedure and then I return the set in type List of entity type in JsonFormat to client. When I return small set for example 100, there is no problem. Body reponse is returned in json format, but when I work with large sets no response is returned. What do you think ?
javascript:
jQuery("#accounts #tranGrid").jqGrid({
url: ncb.NCB + "/Home/GetBillingTransasctions",
datatype: "json",
colNames: ['BillingTransactionID', 'AccountID'],
colModel: [
{
name: 'BillingTransactionID', index: 'BillingTransactionID', sortable: false, align: 'left',
editable: true, edittype: 'text', resizable: true, hidden: true, viewable: false
},
{
name: 'AccountID', index: 'AccountID', sortable: false, align: 'left',
editable: true, edittype: 'text', resizable: true, hidden: true, viewable: false
}
],
rowNum: 10,
rowList: [10, 20, 30],
pager: '#tranPager',
sortname: 'BillingTransactionID',
viewrecords: true,
sortorder: "desc"
}).navGrid("#tranPager", { edit: false, add: false, del: false });
C# code
var obj = new {
total = pTotal,
page,
records = Manager.GetBillTranCount(accountID),
rows = Manager.GetAllBillTranPaged(sRowIndex, eRowIndex, sidx, sord, accountID)
};
return new JsonResult() { Data = obj, JsonRequestBehavior = JsonRequestBehavior.AllowGet };

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.

jqGrid addRowData slowing the process

I have an array of 1000 records and i pass it javascript function. it take almost 20 sec to show data in jqgrid.
I know that addDataRow method is very slow but i could not find any other alternative.
Is there any way i can make it much faster ?
Script:
function GetCommodityGrid(array) {
// alert("Methods");
// var rows = array;
alert(rows.length);
jQuery(document).ready(function () {
jQuery("#list").jqGrid({
// url: 'TestGrid/GridData',
datatype: 'local',
//
colNames: ['COM_NAME', 'COM_CODE', 'DELV_UNITS', 'LOT_SIZE', 'TICK_SIZE', 'TICK_VALUE'],
colModel: [
{ name: 'COM_NAME', index: 'COM_NAME', width: 90, editable: true },
{ name: 'COM_CODE', index: 'COM_CODE', width: 100, editable: true },
{ name: 'DELV_UNITS', index: 'DELV_UNITS', width: 80, align: "right", editable: true },
{ name: 'LOT_SIZE', index: 'LOT_SIZE', width: 80, align: "right", editable: true },
{ name: 'TICK_SIZE', index: 'TICK_SIZE', width: 80, align: "right", editable: true },
{ name: 'TICK_VALUE', index: 'TICK_VALUE', width: 150, sortable: false, editable: true }
],
rowList: ReturnRowList(),
// loadonce: false, // hit only once on the server
rownumbers: true, // show the numbers on rows
pager: '#pager',
sortname: 'COM_NAME',
viewrecords: true, // show the total records on the end of the page
editurl: "TestGrid/EditRecord",
caption: "JSON Example"
});
for (var x = 0; x <= rows.length -1; x++) {
$("#list").addRowData(x, rows[x]);
}
// jQuery("#list").setGridParam({ rowNum: 10 }).trigger("reloadGrid");
$("#list").jqGrid("navGrid", "#pager", { add: false },
{ //the Edit options
closeAfterEdit: true,
afterSubmit: function (response) {
// you should return from server OK in sucess, any other message on error
alert("after Submit");
if (response.responseText == "OKK") {
alert("Update is succefully")
return [true, "", ""]
}
else {
alert("Update failed")
$("#cData").click();
return [false, "", ""]
}
}
});

In general passing your array to data option should do the trick:
jQuery("#list").jqGrid({
datatype: 'local',
data: rows,
...
});
Depending on how your array looks you might also need to add:
...
localReader: { repeatitems: true },
...
On rare cases when your data are extremely specific (you haven't included them in your question) some further changes to localReader might be required.

Search and sorted doesn't work in JqGrid (json)

I am working with JqGrid.
I have some JSON from server
[{"Id":1,"Name":"product1","Price":234,"Size":"Small"},{"Id":18,"Name":"product2","Price":3242,"Size":"Large"}]
and Jquery code
$("#table").jqGrid({
url: '#Url.Action("GetProductsAtJSON", "Product")',
datatype: 'json',
mtype: 'GET',
colNames: ['Id', 'Name', 'Price', 'Size'],
colModel: [
{ name: 'Id', index: 'Id', width: 55, key: true, editable: true, editoptions: { readonly: true }, sortable: true, search:true },
{ name: 'Name', index: 'Name', width: 150, editable: true, editoptions: { size: 25 }, editrules: { required: true }, search: true },
{ name: 'Price', index: 'Price', width: 100, align: 'center', editable: true, editoptions: { size: 25 }, editrules: { required: true, number: true, minValue: 1, maxValue: 10000 } },
{ name: 'Size', index: 'Size', width: 150, editable: true, edittype: "select", editoptions: { value: "0:Large;1:Medium;2:Small" } }
],
pager: '#pager',
rowNum: 10,
rowList: [10, 20, 30],
sortname: 'Id',
sortorder: "asc",
viewrecords: true,
caption: 'All product',
height: '400',
jsonReader: {
repeatitems: false,
loadonce: true,
id: "Id",
root: function (obj) { return obj; },
page: function (obj) { return 1; },
total: function (obj) { return 1; },
records: function (obj) { return obj.length; }
}
});
I have read the documentation and a lot of forums, but I don't understand why sorting and search doesn't work. Maybe my JSON format is incorrect and I must write total page records, but that's not working either. I use key: true from rows id, but it's not working.
What am I doing wrong?

There are some small errors in your code:
loadonce: true is jqGrid option and not the property of jsonReader
You should use sorttype property for columns which content should be interpreted not as a text. For example you should add sorttype: "integer" to the definition of 'Id' and 'Price' columns
I recommend you to consider whether the value editoptions: {value: "0:Large;1:Medium;2:Small"} is what you need. It will be important for edition only.
I recommend you additionally to use gridview: true to improve performance of the grid, use autoencode: true to interpret the values in JSON input as textes instead of HTML fragments and use height: 'auto' to have better look of the grid.
To have local searching of data you need either use navGrid or filterToolbar.
The demo is an example of fixing of your code.
