Sorting of jqGrid (v4.1.2) treegrid not working with Ajacency Model

I have been working with jqGrid and there are some useful questions and answers regarding the Adjacency model and I have got everything I need hooked up and working except sorting.

The problem is actually replicated in the answer link above. Can anyone see what needs fixing? Oleg appears to be the expert on this!

I have tried the options in this question but I think the current version (4.1.2) may have a new bug? Please prove me wrong.

I also see the example on http://trirand.com/blog/jqgrid/jqgrid.html > New in 3.4 > Tree grid Adjacency Model works but that example is not using the loaded:true property as described in the first referenced answer of this question

You are right. It was small bug in the data from my previous answers about

After some debugging I find out that the error is very simple: one should use parent: "null" or parent: null in the data instead of parent: "".

Additionally you have to define sorttype parameters in the grid to have sorting correctly with any data other as texts.

How you can see the modified demo support now the local sorting correctly:

enter image description here

First will be sorted root elements by the chosen column and then recursively all its children.

To make easy to find the new code in the searching engine I include the code of the demo below:

var mydata = [
        {id: "1", name: "Cash",        num: "100", debit: "400.00",  credit: "250.00",  balance: "150.00",   enbl: "1", level: "0", parent: "null", isLeaf: false, expanded: false, loaded: true},
        {id: "2", name: "Cash 1",      num: "1",   debit: "300.00",  credit: "200.00",  balance: "100.00",   enbl: "0", level: "1", parent: "1",    isLeaf: false, expanded: false, loaded: true},
        {id: "3", name: "Sub Cash 1",  num: "1",   debit: "300.00",  credit: "200.00",  balance: "100.00",   enbl: "1", level: "2", parent: "2",    isLeaf: true,  expanded: false, loaded: true},
        {id: "4", name: "Cash 2",      num: "2",   debit: "100.00",  credit: "50.00",   balance: "50.00",    enbl: "0", level: "1", parent: "1",    isLeaf: true,  expanded: false, loaded: true},
        {id: "5", name: "Bank\'s",     num: "200", debit: "1500.00", credit: "1000.00", balance: "500.00",   enbl: "1", level: "0", parent: "null", isLeaf: false, expanded: true,  loaded: true},
        {id: "6", name: "Bank 1",      num: "1",   debit: "500.00",  credit: "0.00",    balance: "500.00",   enbl: "0", level: "1", parent: "5",    isLeaf: true,  expanded: false, loaded: true},
        {id: "7", name: "Bank 2",      num: "2",   debit: "1000.00", credit: "1000.00", balance: "0.00",     enbl: "1", level: "1", parent: "5",    isLeaf: true,  expanded: false, loaded: true},
        {id: "8", name: "Fixed asset", num: "300", debit: "0.00",    credit: "1000.00", balance: "-1000.00", enbl: "0", level: "0", parent: "null", isLeaf: true,  expanded: false, loaded: true}
    ],
    grid = $("#treegrid");

$.jgrid.formatter.integer.thousandsSeparator=',';

grid.jqGrid({

    jsonReader: {
        repeatitems: false,
        root: function (obj) { return obj; },
        page: function () { return 1; },

Answer

By sorting, do you mean, auto-sorting the tree options such that they fall under the appropriate nodes, or being able to sort by other rows (the second of which doesn't really make sense, as the tree organizes the data, so I'm not sure how sorting would make sense.)

Here is a jsFiddle with a local adjacency tree - is this a better description of your problem? For example, in the data below, the id = 4 or 5 should belong to id = 1, but instead they show up under 3.

Here, the data is:

var mydata = [
    {id: "1", label:"No 1", number:"02200220", status:"OPEN", level:"0", parent: "", isLeaf: false, expanded:true, loaded:true},
    {id: "2", label:"No 2", number:"77733337", status:"ENTERED", level:"0", parent: "", isLeaf: false, expanded:true, loaded:true},
    {id: "6", label:"No 2a", number:"12345123", status:"WIRED", level:"1", parent: "2", isLeaf: true, expanded:false, loaded:true},
    {id: "3", label:"No 3", number:"02200111", status:"OPEN", level:"0", parent: "", isLeaf: false},
    {id: "4", label:"No 1a", number:"02200221", status:"OPEN", level:"1", parent: "1", isLeaf: true, expanded:false, loaded:true},
    {id: "5", label:"No 1b", number:"02242320", status:"CLOSED", level:"1", parent: "1", isLeaf: true, expanded:false, loaded:true}
];
