I am having a strange problem. I have a TreePanel function which I call on index page load. Treepanel function is as below:

TreePanel = function (config) {

this.treeDiv = config.treeDiv;

this.actionURL = config.actionURL;

$.getJSON(this.actionURL, null, initTree);

$(this.treeDiv).on("igtreeselectionchanged", function (sender, eventargs) {

var node = eventargs.selectedNodes[0];

debugger;

LoadSearch(node);

});

}

Problem is, this function works only when I run the application first time, next time onwards, it doesn't fire tree selection changed event at all.

Also Konstantine, on a separate thread, I had posted another question for which I did got an answer from not from infragistisc team @ http://ko.infragistics.com/community/forums/p/83672/418240.aspx which was causing this tree issue.

It is easy to reproduce, instead of using Jquery 1.7.x version, use JQuery 1.9.x with Ignite UI 2013.1. Once I got back library from 1.7.x, it worked normally. So I assume, with Ignite UI, you cannot/should not upgrade you JQuery version. Please correct me if I am wrong?

My code for creating Tree is pretty basic as shown in various examples in Ignite UI samples.

Above (first post in this thread) I call initTree functon on $.getJSON(this.actionURL, null, initTree);

Rest of the code is above where I fire selection changed event, and below is code where I am building tree.

initTree =function (data) {

    $("#treeView").igTree({

        initialExpandDepth: 1,

        dataSourceType:'json',

        bindings: {

            textKey:'MainLabel',

            valueKey:'MainId',

            singleBranchExpand:true,

            childDataProperty:'MainSubjectAreas',

            bindings: {

                textKey:'Label',

                valueKey:'Id',

                childDataProperty:'Categories',

                bindings: {

                    textKey:'CategoryName',

                    valueKey:'CategoryId'

                }

            }

        },

        dataSource: data.SubjectAreas

    });

}

Hi there,

Could you please provide us with a little more information about this issue. A small sample reproducing it would be very useful. Thanks a lot in advance!

I forgot 1 thing, it only works when I clear the browser history, but again it only works 1 time. So basically I have to clear brower history everytime I run the application.
