RadTreeListView in UserControl Access SelectedItems collection

[Jonathan]

Is there a quicker way of selecting / deselecting groups of children items in RadTreeListView ??

if (e.AddedItems.Count > 0)
            {
                foreach (NodesModel i in e.AddedItems)
                {
                    if (i.Name != "WHDLoad")
                    {
                        if (i.Items.Count > 0)
                        {
                            foreach (NodesModel x in i.Items)
                            {
                                {
                                    //x.IsSelected = true;
                                    Nodes.SelectedItems.Add(x);
                                }
                            }
                        }
                    }
                }
            }
