    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,

    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:
