get_allNodes() returning empty nodes in chrome

[Phani Alla]

Hi There, 

I have a treeview that has around 1100 nodes, I've added a type ahead search for the treeview using onClientKeyPressingHandler on a textbox. I loop through all the nodes of the treeview returned by the get_allNodes() method and look for match by getting the node text using get_text(). This is working well in IE, but in Chrome, the get_allNodes is returning some empty nodes which hence are not being returned as matches, any suggestions/ideas on what I could be doing wrong? I'm including my javascript code i'm using to search. 

function FindAppendages(treeview, textSearch) {

    var radtree = $find(treeview);

    var nodes = radtree.get_allNodes();

    var subsetArray = new Array();

    for (var i = 0; i < nodes.length; i++) {

        var oNode = nodes[i];

        if (oNode.get_text().toLowerCase().match(textSearch.value.toLowerCase()) != null) {

            oNode.set_visible(true);

            var parent = oNode.get_parent();

            if (parent != null) {

                parent.set_visible(true);

                if (parent._text != undefined) {

                    subsetArray.push(parent.get_text());parent.set_expanded(true);

                }

            }

            parent = parent.get_parent();

            if (parent != null) {

                parent.set_visible(true);



                if (parent._text != undefined) {

                    subsetArray.push(parent.get_text());parent.set_expanded(true);

                }

            }

            parent = parent.get_parent();

            if (parent != null) {

                parent.set_visible(true);



                if (parent._text != undefined) {

                    subsetArray.push(parent.get_text());parent.set_expanded(true);

                }

            }

            parent = parent.get_parent();

            if (parent != null) {

                parent.set_visible(true);



                if (parent._text != undefined) {

                    subsetArray.push(parent.get_text());parent.set_expanded(true);

                }

            }

        }

        else {

            var match = false;

            for (var j = 0; j < subsetArray.length; j++) {

                if (oNode.get_text() == subsetArray[j])

                    match = true;

            }

            if (!match)

                oNode.set_visible(false);

        }

    }

}

Thanks,
Phani

Hi Phani Alla,

I wasn't able to reproduce the problem you experience. I have tested one of our demos (http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/checkboxes/defaultcs.aspx) using the following in the console:

var tree = $find("RadTreeView1");

var nodes = tree.getAllNodes();

$telerik.$(nodes).each(function(){console.log(this.get_text());});

And all the nodes names were displayed:
