TreeView not expanding Programmatically

[Daochuen]

Hi

I have issue with Kendo treeview expanding in my MVC project. I try to expand treeview node (which have children nodes) at same time when I select it. The code went through in .js file without error.  but node didn't expand. Could any one tell me what properly be wrong? below are piece of code.  Thanks.

 

        var selectedNode = $("#treeView").data('kendoTreeView').dataItem(e.node); // selectedNode have correct data after this.
        var treeView = $("#treeView").data('kendoTreeView');
        treeView .expand(selectedNode); //Code went through without error

I find out the reason:

expand() required real node as parameter. below code was working.

treeView.expand(e.node);
