How to programmatically select the root node of Kendo UI treeview

Question

I am a Kendo UI newbie. My Asp.net MVC application has a Kendo UI treeview which is set up like follows. Each tree node has a unique Id (e.g. EmployeeId which is integer). How can I programmatically select the root node (which has Id of 1) of Kendo UI treeview and the root node's background color should be high-lighted ? Thank you for your help.

           var _root = new kendo.data.HierarchicalDataSource({
                transport: {
                    read: {
                        cache: false,
                        url: "/Employee/GetEmployees",
                        dataType: "json",
                        data: { employeeId: _selectedId}
                    }
                },
                schema: {
                    model: {
                        id: "Id",
                        hasChildren: "HasChildren",
                        expanded: "expanded",
                        parentId: "parentId",
                        ItemType: "ItemType"
                    }
                }
            });

            _tree = $("#treeView").kendoTreeView({
                dataSource: _root,
                dataTextField: "Name",
                loadOnDemand: true,                
                dataImageUrlField: "Image",
                dataBound: function (e) {
                    handleTreeDataBound(e);
                },
                select: function (e) {
                    handleSelect(e.node);
                }
            });

            treeViewCtrl = $("#treeView").data("kendoTreeView");

Answer 1

You can also use this little piece of code:

treeview.select($('.k-item:first'));

This selects the root node. You could also expand it using:

treeview.expand($('.k-item:first'));

Answer 2

Using the treeview's select method, this is how you select the first node:

treeViewCtrl.select($("#treeView").find(".k-item").first());

If you have more than one root node, then you'll have to use the dataItem method to get the data item and compare its id with the one you want to select.
