Data Binding and Data Templates

RadBook is an ItemsControl and can be populated by using its ItemsSource property.

RadBook contains two additional properties used for templating:

  • LeftPageTemplate - defines a data template for all left pages.

  • RightPageTemplate - defines a data template for all right pages.

Below is an example of how to bind RadBook to a collection of items that display photos and info.

Example 1: Setting up the ItemsSource of RadBook

public partial class MainPage : UserControl 
{ 
    public MainPage() 
    { 
        InitializeComponent(); 
 
        // create the collection of photos 
        ObservableCollection<PhotoItem> myPhotos = new ObservableCollection<PhotoItem>(); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Chrysanthemum", 
            Image = "Chrysanthemum.jpg", 
            DateTaken = DateTime.Parse("3/14/2008 1:59 PM"), 
            Size = "858 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Desert", 
            Image = "Desert.jpg", 
            DateTaken = DateTime.Parse("2/12/2008 3:12 PM"), 
            Size = "458 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Hydrangeas", 
            Image = "Hydrangeas.jpg", 
            DateTaken = DateTime.Parse("3/25/2008 2:22 PM"), 
            Size = "843 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Jellyfish", 
            Image = "Jellyfish.jpg", 
            DateTaken = DateTime.Parse("1/14/2008 4:32 PM"), 
            Size = "456 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Koala", 
            Image = "Koala.jpg", 
            DateTaken = DateTime.Parse("6/14/2008 2:46 PM"), 
            Size = "654 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "LightHouse", 
            Image = "LightHouse.jpg", 
            DateTaken = DateTime.Parse("8/23/2008 3:59 PM"), 
            Size = "930 KB" 
        }); 
        myPhotos.Add(new PhotoItem() 
        { 
            Title = "Penguis", 
            Image = "Penguis.jpg", 
            DateTaken = DateTime.Parse("3/14/2008 1:59 PM"), 
            Size = "623 KB" 
        }); 
        RadBook1.ItemsSource = myPhotos; 
    } 
} 
// create a class representing a single photo 
public class PhotoItem 
{ 
    public string Image { get; set; } 
    public string Title { get; set; } 
    public DateTime DateTaken { get; set; } 
    public string Size { get; set; } 
} 
Partial Public Class MainPage 
        Inherits UserControl 
        Public Sub New() 
            InitializeComponent() 
            ' create the collection of photos ' 
            Dim myPhotos As New ObservableCollection(Of PhotoItem)() 
            myPhotos.Add(New PhotoItem() With {.Title = "Chrysanthemum", .Image = "Chrysanthemum.jpg", .DateTaken = Date.Parse("3/14/2008 1:59 PM"), .Size = "858 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "Desert", .Image = "Desert.jpg", .DateTaken = Date.Parse("2/12/2008 3:12 PM"), .Size = "458 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "Hydrangeas", .Image = "Hydrangeas.jpg", .DateTaken = Date.Parse("3/25/2008 2:22 PM"), .Size = "843 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "Jellyfish", .Image = "Jellyfish.jpg", .DateTaken = Date.Parse("1/14/2008 4:32 PM"), .Size = "456 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "Koala", .Image = "Koala.jpg", .DateTaken = Date.Parse("6/14/2008 2:46 PM"), .Size = "654 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "LightHouse", .Image = "LightHouse.jpg", .DateTaken = Date.Parse("8/23/2008 3:59 PM"), .Size = "930 KB"}) 
            myPhotos.Add(New PhotoItem() With {.Title = "Penguis", .Image = "Penguis.jpg", .DateTaken = Date.Parse("3/14/2008 1:59 PM"), .Size = "623 KB"}) 
            RadBook1.ItemsSource = myPhotos 
        End Sub 
    End Class 
    ' create a class representing a single photo ' 
    Public Class PhotoItem 
        Public Property Image() As String 
        Public Property Title() As String 
        Public Property DateTaken() As Date 
        Public Property Size() As String 
    End Class 

Example 2: Binding RadBook to a collection of business objects

    <Grid x:Name="LayoutRoot" Background="Purple"> 
        <Grid.Resources> 
            <!--  Declare the template used for the left pages  --> 
            <DataTemplate x:Key="LeftPageTemplate">

                    </StackPanel> 
                </StackPanel> 
            </DataTemplate> 
            <!--  Declare the template used for the right pages  --> 
            <DataTemplate x:Key="RightPageTemplate"> 
                <StackPanel Margin="10" Background="LightBlue">

                               Text="{Binding Title}" /> 
                    <Image Width="240"  
                           Height="320" 
                           Source="{Binding Image}" /> 
                    <StackPanel HorizontalAlignment="Right" Orientation="Horizontal"> 
                        <TextBlock FontWeight="Bold" Text="Date Taken:" />

                    </StackPanel> 
                </StackPanel> 
            </DataTemplate> 
        </Grid.Resources> 
        <telerik:RadBook x:Name="RadBook1"  
                         Margin="50" 
                         LeftPageTemplate="{StaticResource LeftPageTemplate}" 
                         RightPageTemplate="{StaticResource RightPageTemplate}" />
