    great article!!

    I'm doing the same thing but I have two listview controls on for books and one for chapters.

    I have coded the Library, Book, Chapter do objects to be observableCollections and all properties are public and dependency properties. I have my data in a layered object called Library and it has one Library even tho it is a observable collections as is my list of books and list of chapters. Can I set this Library object to data context?

    ex: of xml data:

    <lib title="lib1">
      <books>
        <book title="book1">
          <chapters>
            <chapter title="chapter1"/>
            <chapter title="chapter2"/>
          </chapters>
        <book>
      </books>
    </lib>

    You get the idea. I want to set one list to books and other to chapters. How do I do this and right now both list are blank showing no columns at all?

    I have read both articles #1 and #3.
