Child node doesn't be checked unless expend it or check twice

[JC Software Services, Inc.]

I use TreeViewBuilder.Items to build tree view.
Child nodes doesn't ​be checked when I check parent node without expend nodes, but if I check ​the parent node again(without expend too), child nodes will be checked.

@using Kendo.Mvc.UI.Fluent;
@model List<AuthViewModel>
@functions
{
    public static void ShowTree(TreeViewItemFactory helper, IEnumerable<AuthViewModel> nodes)
    {
        foreach (var node in nodes)
        {
            helper.Add()
                .Id(node.ID)
                .Text(node.NAME)
                .Checked(node.IsChecked)
                .Expanded(false)
                .Items(items =>
                {
                    if (node.Childs.Count() > 0)
                    {
                        ShowTree(items, node.Childs);
                    }
                });
        }
    }
}

@(Html.Kendo().TreeView()
    .Name("authTree")
    .Checkboxes(checkboxes => checkboxes
        .Name("checkedFiles")
        .CheckChildren(true)
    )
    .Items(root =>
        {
            ShowTree(root, Model);
        }
    )
)

It is something wrong in my post.

1. I mean expand not expend.
2. If I check the parent node after expand the child node, it still not check the child node too.

Hello,

The described behavior indicates that the initial state is invalid - the parent node is checked but not all of its children are checked. If this is the case then you should change the initial parent state to false or make all children checked.
