Silverlight普通控件数据绑定

1.绑定控件属性的值

<TextBlock  Text="{Binding Value, Mode=OneWay, ElementName=MyNewSlider}" />

前台代码：

 1  <Grid x:Name="LayoutRoot">
 2         <StackPanel x:Name="myStackPanel" Orientation="Vertical" Width="200" >
 3             <TextBlock x:Name="Title" 
 4                        Text="{Binding Title,Mode=OneWay}" 
 5                        />
 6             <TextBlock x:Name="Author" 
 7                        Text="{Binding Author,Mode=OneWay}" 
 8                        />
 9               <ListBox x:Name="Chapters" 
10                        Height="60"
11                        ItemsSource="{Binding Chapters,Mode=OneWay}"    
12                        />
13             <CheckBox x:Name="YesPublished" 
14                        Content="Published?" 
15                        IsChecked ="{Binding IsPublished ,Mode=TwoWay}"
16                        />
17             <Button x:Name="btnChange" Content="Change Book" />
18         </StackPanel>
19     </Grid>

Book类：

 public class Book
    {
        //必须为get和set访问器，否则不改变；
         public string Title { get; set; }
        public string Author { get; set; }
        public bool IsPublished{ get; set; }
        public List<string> Chapters { get; set; }
    }

后台代码：

 1   public partial class MainPage : UserControl
 2     {
 3         Book b1;
 4         Book b2;
 5         public MainPage()
 6         {
 7             InitializeComponent();
 8             Loaded += new RoutedEventHandler(MainPage_Loaded);
 9         }
10 
11         void MainPage_Loaded(object sender, RoutedEventArgs e)
12         {
13             this.SetBookData();
14             myStackPanel.DataContext = b1;
15             this.btnChange.Click += new RoutedEventHandler(btnChange_Click);
16         }
17         private void SetBookData()
18         {
19             this.b1 = new Book() 
20             {
21                 Title = "Title1",
22                 Author = "Author1",
23                 IsPublished = true, 
24                 Chapters = new List<string>() { "b1_1", "b1_2", "b1_3" }
25             };
26             this.b2 = new Book()
27             {
28                 Title = "Title2",
29                 Author = "Author2",
30                 IsPublished =false,
31                 Chapters = new List<string>() { "b2_1", "b2_2", "b2_3" }
32             };
33         }
34 
35         void btnChange_Click(object sender, RoutedEventArgs e)
36         {
37             if ((Book)myStackPanel.DataContext == this.b1)
38                 myStackPanel.DataContext = this.b2;
39             else
40                 myStackPanel.DataContext = this.b1;
41         }
42     }
