Thanks. Just fixed the problem. It is in GitHub.

The fix is little bit diffrent.

var mydataSrc = [{id:"1", name:"Cash", num:"100", level:"0", parent:"", isLeaf:false, expanded:false, loaded:true }, {id:"2", name:"Cash 1", num:"1", level:"1", parent:"1", isLeaf:false, expanded:false, loaded:true },{id:"3", name:"Sub Cash 1",num:"1", level:"2", parent:"2", isLeaf:true, expanded:false, loaded:true },{id:"4", name:"Cash 2", num:"2", level:"1",parent:"1", isLeaf:true, expanded:false, loaded:true },{id:"5", name:"Bank\'s", num:"200", level:"0", parent:"",isLeaf:false, expanded:false, loaded:true },{id:"6", name:"Bank 1", num:"1", level:"1", parent:"5", isLeaf:true,expanded:false, loaded:true },{id:"7", name:"Bank 2", num:"2", level:"1", parent:"5", isLeaf:true, expanded:false,loaded:true },{id:"8", name:"Fixed asset", num:"300", level:"0", parent:"", isLeaf:true, expanded:false,loaded:true }];

grid:

var grid = $('<table/>').appendTo('body');    grid.jqGrid({        treedatatype: "local",        datatype: "local",        datastr: [],        colNames:["Id","Account","Acc Num"],        colModel:[            {name:'id', index:'id', width:1, hidden:true, key:true},            {name:'name', index:'name', width:180},            {name:'num', index:'acc_num', width:80, align:"center"}        ],        height: 'auto',        gridview: true,        rowNum: 10000,        sortname: 'id',        treeGrid: true,        treeGridModel: 'adjacency',        ExpandColumn: 'name',        caption: "Test"    });

Adding data:

var row;

for (var i = 0, l = mydataSrc.length; i < l; ++i) {

row = mydataSrc[i];

grid.jqGrid ('addChildNode', row.id, row.parent, row);

}

My solution:

In jquery.jqGrid.js did the following changes in addChildNode function

1) 

//parentdata[expanded] = true;

2) 

.find("div.tree-leaf").removeClass($t.p.treeIcons.leaf+" tree-leaf").addClass((parentdata[expanded] ? $t.p.treeIcons.minus+" tree-minus" : $t.p.treeIcons.plus+" tree-plus"));

3) 

//data[expanded] = false;

if (data[expanded] === undefined) {

data[expanded] = false;

}

A grid (treegrid) configuration will help and how look your row?

Regards

grid.jqGrid ('addChildNode', row.id, row.parent, row);
