Default No data is shown after Binding

I followed the book to set up the data binding in Blend in Chapter 12. However, the data didn't shown in the textbook. Would you point me what I missed. Thansk in advance.

The following is my MaingPage.xaml.


Code:
<phone:PhoneApplicationPage
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
	xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
	xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
	xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
	mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="800"
	x:Class="test.MainPage"
	SupportedOrientations="Portrait" Orientation="Portrait"
	shell:SystemTray.IsVisible="True">

	<phone:PhoneApplicationPage.FontFamily>
		<StaticResource ResourceKey="PhoneFontFamilyNormal"/>
	</phone:PhoneApplicationPage.FontFamily>
	<phone:PhoneApplicationPage.FontSize>
		<StaticResource ResourceKey="PhoneFontSizeNormal"/>
	</phone:PhoneApplicationPage.FontSize>
	<phone:PhoneApplicationPage.Foreground>
		<StaticResource ResourceKey="PhoneForegroundBrush"/>
	</phone:PhoneApplicationPage.Foreground>

	<Grid x:Name="LayoutRoot" Background="Transparent" d:DataContext="{d:DesignData /SampleData/OrderSampleData.xaml}">
		<Grid.RowDefinitions>
			<RowDefinition Height="Auto"/>
			<RowDefinition Height="*"/>
		</Grid.RowDefinitions>

		<!--TitlePanel contains the name of the application and page title-->
		<StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
			<TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
			<TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
		</StackPanel>

		<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
			<TextBox Height="48" Margin="68,71,204,0" TextWrapping="Wrap" Text="ox" VerticalAlignment="Top"
				x:Name="txtBinding" DataContext="{Binding Address, Mode=TwoWay}" Foreground="#FF6EE275" Background="#BFE48888"/>
		</Grid>
	</Grid>
</phone:PhoneApplicationPage>
There are my code behind on MainPage.xaml:
Code:
namespace test
{
    public partial class MainPage : PhoneApplicationPage
    {
        public MainPage()
        {
            InitializeComponent();
			
			 DataContext = new Order()
            {
                Address = "My house",
                Total = 500,
                Products = new ObservableCollection<Product>
				{
					new Product
					{
						Name="Gizmos", 
						Price=200, 
						Description="something something something", 
						IsSelected=true
					},
        }
			};
		}
    }
}
