WPF Listview Access to SelectedItem and subitems

Question

Ok, I am having more problems with my C# WPF ListView control. Here it is in all its glory:

Answer 1

    var items = from item in xdoc.Descendants("Book")
            select new Book()                                   //  <---
            {
                ISBN = (string)item.Element("ISBN"),
                Title = (string)item.Element("Title"),
                Author = (string)item.Element("Author"),
            };

foreach (var item in items)
{
    listView1.Items.Add(item);
}

I have got an issue with code above, once I use it, my listView did not list any of those values. I do not know if that will help you or if that is correct but after a few tests I added () after "select new Book" and then ListView could show all fields correctly for me.
