Can't get the treview instance

[Luis]

I'm creating a treeview in MVC using the TreeViewBuilder. like this

 Html.Kendo().TreeView().Name("TreeViewTemplateBiding")....

I need to get access to the treeview instance in a script. It's not an event, so I can't rely on the tree passing the instance to my function.

I'm trying, as instructed:

var myTree = $("#TreeViewTemplateBiding").data('kendoTreeView')

This does not work, it returns 'undefined'. In fact I can see that $("#TreeViewTemplateBiding") has no data at all.

Please assist.

Hi Luis,

I've tried the following configuration to test this behavior and it works as expected on my side:

@(Html.Kendo().TreeView()
        .Name("TreeViewTemplateBiding")
        .Items(treeview =>
        {
            treeview.Add().Text("Furniture")
                .Items(root =>
                {
                    root.Add().Text("Tables & Chairs");
                    root.Add().Text("Sofas");
                    root.Add().Text("Occasional Furniture");
                });

            treeview.Add().Text("Decor")
                .Expanded(true)
                .Items(root =>
                {
                    root.Add().Text("Bed Linen");
                    root.Add().Text("Throws");
                });

            treeview.Add().Text("Storage")
                .Items(root =>
                {
                    root.Add().Text("Wall Shelving");
                    root.Add().Text("Kids Storage");
                    root.Add().Text("Baskets");
                    root.Add().Text("Multimedia Storage");
                });
        })
)

Added a button to call the logic:

<button onclick="buttonClick();">Access TreeView</button>

And this is the script logic:

<script>
    function buttonClick() {
        var treeView = $("#TreeViewTemplateBiding").data().kendoTreeView;
        treeView.expand(treeView.items()[0]);
    }
</script>

Please try this configuration and verify that it works properly on your side, too.
