Expand treeview functionality is not working properly

[Srikanth]

Hi,

After seeing the demo, I have implemented treeview checkboxes. After implementing all code logic, when I am trying to expand treeview on any parent node is not being expanded. Please  find below code 

GroupsTree.chtml :

<div id="treeview">
   
     @(Html.Kendo().TreeView()
                .Name("treeview")
                .Checkboxes(true)
                .Items(treeview =>
                {
                    treeview.Add().Text("Furniture").Id("1")
                        .Expanded(true)
                        .Items(furniture =>
                        {
                            furniture.Add().Text("Tables & Chairs").Id("2");
                            furniture.Add().Text("Sofas").Id("3");
                            furniture.Add().Text("Occasional Furniture").Id("4");
                        });

                    treeview.Add().Text("Decor").Id("5")
                        .Expanded(true)
                        .Items(furniture =>
                        {
                            furniture.Add().Text("Bed Linen").Id("6");
                            furniture.Add().Text("Curtains & Blinds").Id("7");
                            furniture.Add().Text("Carpets").Id("8");
                        });
                })
            )
</div>
