Out-of-browser applications don t have the benefit of the browser-based navigation UI. From a user experience standpoint, this is excellent, because you ll want to provide your own in-theme navigation controls anyway. Consider the Microsoft Zune software client (see figure 15.8): it uses familiar navigation metaphors but looks different from a web browser. The Zune client uses some of the traditional controls and navigation concepts (primarily links and the Back button) but provides a custom look and feel. The Zune client also eschews the use, in this case, of a Forward button. A user interface along the lines of the Zune client is well within the capabilities of a Silverlight out-of-browser application with custom chrome and navigation. In this section, we ll look at what it takes to create custom navigation controls, hook up to an appropriate journal, and support navigation out of the browser.

a shell of a navigation application that integrated with the browser to provide standard URI and back and forward navigation. The next step is to take this application out-of-browser and provide your own custom navigation user interface.
CREATING THE NAVIGATION CONTROLS
The application needs, at a minimum, a Back button and a Forward button. For this, you ll use the metro theme (Windows Phone 7 and Zune) icons from http:// metro.windowswiki.info/. From that set, drag both the back.png and next.png black icons into the project s Assets folder. When they re in place, modify MainPage.xaml to add the XAML in listing 15.3 right before the closing Grid tag at the bottom of the file.
Listing 15.3 The Back and Forward buttons on MainPage.xaml
<Grid x:Name="OutOfBrowserNavigationControls" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="15"> <Grid.Resources> <Style TargetType="Button"> <Setter Property="Cursor" Value="Hand" /> <Setter Property="Margin" Value="2" /> <Setter Property="Opacity" Value="0.5" /> <Setter Property="VerticalAlignment" Value="Top" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal" /> <VisualState x:Name="Disabled"> <Storyboard> <DoubleAnimation Duration="0" Storyboard.TargetName="Content" Storyboard.TargetProperty="Opacity" To=".2" /> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <ContentPresenter x:Name="Content" /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </Grid.Resources> Navigation <StackPanel Orientation="Horizontal"> button <Button x:Name="BackButton" Click="BackButton_Click" Width="40" Height="40"> <Image Source="Assets/back.png" /> </Button>

405 Navigation button
The XAML in listing 15.3 adds two buttons: a Back button and a Forward button. The style resource (resources are covered in chapter 23) creates a button that has no real appearance other than its content. When you run the application, the UI displays the two new buttons at upper left on the main page, as shown in figure 15.9.
The new navigation buttons appear at upper left in the user interface.
The new UI looks pretty good. With the buttons in place, you ll need to wire them up to the content frame to make navigation happen.
WIRING UP THE BUTTONS
In the button-click event handlers for the two new navigation buttons, you ll place some code similar to what you wrote in listing 15.2 earlier in this chapter. This time, though, you ll use the Frame class directly rather than the NavigationService class. Listing 15.4 shows the code-behind for the MainPage.xaml page.
Listing 15.4 Navigation code in MainPage.xaml.cs
private void BackButton_Click(object sender, RoutedEventArgs e) { if (ContentFrame.CanGoBack)

Navigation and dialogs
private void ForwardButton_Click(object sender, RoutedEventArgs e) { if (ContentFrame.CanGoForward) ContentFrame.GoForward(); }
With this code in place, you can use either the browser buttons or the custom navigation buttons to move backward and forward through the journal. There s currently no visual cue indicating whether either navigation option is available, though. You can do this using binding, because the CanGoBack and CanGoForward properties of the Frame class are implemented as dependency properties. As you learned in chapter 11, you can use element binding to get to the properties on ContentFrame, as shown here:
<Button x:Name="BackButton" IsEnabled="{Binding CanGoBack, ElementName=ContentFrame}" ... </Button> <Button x:Name="ForwardButton" IsEnabled="{Binding CanGoForward, ElementName=ContentFrame}" ... </Button>
With that in place, you ll see the Forward and Back buttons ghost out when the function isn t available. Note how the buttons are in sync with the browser navigation buttons. Now, let s try it without the browser.
