Silverlight数据绑定简单例子

新建一个类：Book

using System.Collections.Generic;
using System.ComponentModel;
namespace GlobalStyles
{
    public class Book : INotifyPropertyChanged
    {
        private string bookTitle;
        private string bookAuthor;
        private int quantityOnHand;
        private bool isPublished;
        private List<string> myChapters;

// implement the required event for the interface
public event PropertyChangedEventHandler PropertyChanged;

        public string Title
        {
            get { return bookTitle; }
            set
            {
                bookTitle = value;
                NotifyPropertyChanged("Title");
            }       // end set
        }           // end property

        public string Author
        {
            get { return bookAuthor; }
            set
            {
                bookAuthor = value;
                NotifyPropertyChanged("Author");
            }       // end set

}

        public List<string> Chapters
        {
            get { return myChapters; }
            set
            {
                myChapters = value;
                NotifyPropertyChanged("Chapters");
            }
        }

        public bool IsPublished
        {
            get { return isPublished; }
            set
            {
                isPublished = value;
                NotifyPropertyChanged("IsPublished");
            }       // end set
        }

        public int QuantityOnHand
        {
            get { return quantityOnHand; }
            set
            {
                quantityOnHand = value;
                NotifyPropertyChanged("QuantityOnHand");
            }       // end set
        }

        // factoring out the call to the event
        public void NotifyPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this,
                    new PropertyChangedEventArgs(propertyName));
            }

}
} // end class
}

            InitializeComponent();
            Loaded += new RoutedEventHandler(Page_Loaded);
        }

        void Page_Loaded(object sender,
            RoutedEventArgs e)
        {
            // event handler for change button
            Change.Click +=
                new RoutedEventHandler(Change_Click);

            // initial book values
            b1 = new Book();
            InitializeBleak(b1);
            currentBook = b2 = new Book();
            InitializeProgramming(b2);
            SetDataSource();
        }

            b.Chapters = new List<string>() { "Introduction", "Controls", "Events", "Styles" };
        }

        private void InitializeBleak(Book b)
        {
            b.Title = "Bleak House";

               "A Morning Adventure", "Quite at Home", "The Ghosts Walk", "Covering Sins", "Signs and Tokens", "The Law Writer"};
        }

        void Change_Click(object sender, RoutedEventArgs e)
        {
            if (currentBook == b1)
                currentBook = b2;
            else
                currentBook = b1;
            SetDataSource();
        }

        void SetDataSource()
