this.p is undefined jqgrid - jqgrid

Question

I have an interesting issue. I have done this on multiple pages with multiple grids. The first grid works fine the second grid in this case fails to load. and give the following error:
this.p is undefined
...sArray(i)){P=true;h="last";U=f}else{i=[i];P=false}this.each(function(){var D=i.l... line 140 jquery.jqGrid.min.js
The user doble clicks on a row and that sets some variables and then calls the function locationGrid().
Like I said this has worked for me multiple times in the past, however on this page it fails. I have double checked and I am getting data back as shown below:
{"d":"{\"total\":1,\"page\":0,\"records\":1,\"rows\":[{\"invPartLocId\":1053,\"inventoryMasterId\":5,\"location\":null,\"itemType\":\"S\",\"currentQanity\":1,\"adjustedQauntity\":0,\"newLocationQty\":0,\"deptCode\":\"1401 \"}]}"}
Any help would be appreciated.
function locationGrid() {
$('#invLocAdjustGrid').jqgrid({
height: 290,
loadui: "block",
datatype: function (rdata) { getLocationData(rdata); },
colNames: ['invPartID', 'locationPartID', 'Loctaion', 'Type', 'Current QTY', 'Adjusted QTY', 'New Location QTY', 'Dept. Code'],
colModel: [
{ name: 'invPartLocId', width: 2, sortable: false, editable: false, hidden: true },
{ name: 'inventoryMasterId', width: 2, sortable: false, editable: false, hidden: true },
{ name: 'location', width: 250, editable: false, sortable: false },
{ name: 'itemType', width: 120, editable: false, sortable: false, align: 'center' },
{ name: 'currentQanity', width: 50, editable: false, sortable: false },
{ name: 'adjustedQauntity', width: 50, editable: false, sortable: false },
{ name: 'newLocationQty ', width: 50, editable: false, sortable: false },
{ name: 'deptCode', width: 50, editable: false, sortable: false }
],
pager: jQuery('#rptCodesPager'),
viewrecords: true,
width: 890,
gridComplete: function () {
$('#load_invLocAdjustGrid').hide();
$(this).prop('p').loadui = 'enable';
$('#lui_invLocAdjustGrid').hide();
},
afterInsertRow: function (rowid, aData) {
},
ondblClickRow: function (rowid) {
var myID = $('#invLocAdjustGrid').getCell(rowid, 'invPartLocId');
Ldclicked(myID);
}
});
}
function getLocationData(rdata) {
var theID = tempID;
tempID = "";
var myDTO = { 'id': theID };
var toPass = JSON.stringify(myDTO);
$.ajax({
type: 'POST',
contentType: "application/json; charset=utf-8",
dataType: "json",
url: "INV_Inventory_Adjustment.aspx/getInventoryLocationById",
data: toPass,
success: function (data, textStatus) {
if (textStatus == "success")
ReceivedLocationData(JSON.parse(getMain(data)).rows);
},
error: function (data, textStatus) { alert('An error has occured retrieving data!'); }
});
}
function ReceivedLocationData(data) {
var thegrid = $('#invLocAdjustGrid');
var isGood = data.length;
for (var i = 0; i < isGood; i++) {
thegrid.addRowData(i + 1, data[i]);
}
}

Sorry, but your code is buggy. Moreover I recommend you to rewrite the whole code and I try to explain why.
The first important error is that you use $('#invLocAdjustGrid').jqgrid({...}); in the locationGrid instead of $('#invLocAdjustGrid').jqGrid({...});. JavaScript is case sensitive, so it's very important to use jqGrid instead of jqgrid.
Next problem exist because you use some variables and functions tempID, Ldclicked and getMain which you not defined in the posted code.
After making minimal changes the demo works. I commented only "POST" to use HTTP GET because I get the JSON directly from the file and have no active components on the wed server.
One more problem which you clear have is that your server code serialize the results twice. Typically one have the problem because of wrong usage of ASMX WebMethods. One should not convert the object to JSON manually. Instead of that one need just return the object itself. Because of the problem the d property of the JSON are not the object itself and is a string which should be one more time be parsed:
{
"d": "{\"total\":1,\"page\":0,\"records\":1,\"rows\":[{\"invPartLocId\":1053,\"inventoryMasterId\":5,\"location\":null,\"itemType\":\"S\",\"currentQanity\":1,\"adjustedQauntity\":0,\"newLocationQty\":0,\"deptCode\":\"1401 \"}]}"
}
Even such wrong formatted data can be read by jqGrid without usage datatype as function. Moreover you should always use gridview: true and never use afterInsertRow and almost never use addRowData. The modified code can be about the following:
var tempID = "abc";
$('#invLocAdjustGrid').jqGrid({
url: "INV_Inventory_Adjustment.aspx/getInventoryLocationById",
mtype: "POST",
datatype: "json",
postData: {
id: function () { return tempID; } // ??? I don't know which data should be send
},
ajaxGridOptions: { contentType: "application/json" },
serializeRowData: function (data) {
return JSON.stringify(data);
},
beforeProcessing: function (data) {
$.extend (true, data, $.parseJSON(data.d));
},
jsonReader: {repeatitems: false},
loadonce: true,
colNames: ['invPartID', 'locationPartID', 'Loctaion', 'Type', 'Current QTY', 'Adjusted QTY', 'New Location QTY', 'Dept. Code'],
colModel: [
{ name: 'invPartLocId', width: 2, key: true, hidden: true },
{ name: 'inventoryMasterId', width: 2, hidden: true },
{ name: 'location', width: 250 },
{ name: 'itemType', width: 120, align: 'center' },
{ name: 'currentQanity' },
{ name: 'adjustedQauntity' },
{ name: 'newLocationQty ' },
{ name: 'deptCode' }
],
cmTemplate: {sortable: false, width: 50},
pager: '#rptCodesPager',
viewrecords: true,
gridview: true,
loadui: "block",
height: 290,
width: 890,
ondblClickRow: function (rowid) {
//Ldclicked(rowid);
}
});
The next demo demonstrate that the code work. I included in the demo the option loadonce: true which can be helpful for you too.
