WP7: Navigating to a page in different assembly

In this quick tip I am going to demonstrate how to navigate to a page in different assembly in Windows Phone 7.

Generally when you want to navigate to a page in the same assembly there are three basic ways to navigate between pages in your app.

• Using the HyperlinkButton and set the NavigateUri property to the name of the page that you want to navigate to.
• NavigationService.Navigate()  - navigate to any particular page using its uri.
• NavigationService.GoBack() - this will take the user back one page in their navigation history. (Do not forget to check if there is a page in the navigation history.)

WP7 Uri String Format

• Internal Page

/{PathToResource}

• External Page

/{assemblyName};component/{PathToResource}

For more information about how to access a page by its Uri and all supported Uri formats take a look at the MSDN Documentation: Resource Files

Navigate to a page in external assembly

NOTE: If you want to navigate to an external assembly you must add a reference to it in the current project.

Now lets create two separate Windows Phone 7 Application projects called:

NavigationTestProject            WP7SampleProject12

We will navigate to the NavigationTestProject  MainPage from our WP7SampleProject12.

Example1: Navigate to external assembly using NavigationService.Navigate()

Here is the source code that shows how to navigate to external assembly and how to navigate to a page from the current assembly using the NavigationService.Navigate() method:

private void Button_Click(object sender, RoutedEventArgs e)
{
    //Navigate to a page in an external referenced assembly
    NavigationService.Navigate(new Uri("/NavigationTestProject;component/MainPage.xaml", UriKind.Relative));
}

private void Button_Click_1(object sender, RoutedEventArgs e)
{
    //Navigate to a page in the current assembly
    NavigationService.Navigate(new Uri("/Page1.xaml", UriKind.Relative));
}

Example2: Navigate to external assembly using HyperlinkButton 

Here is the source code that shows how to navigate to external assembly and how to navigate to a page from the current assembly using HyperlinkButton :

<HyperlinkButton NavigateUri="/NavigationTestProject;component/MainPage.xaml" Content="Navigate to external assembly"/>

<HyperlinkButton NavigateUri="/Page1.xaml" Content="Navigate to a page in this assembly"/>

NOTE: In this way you can also load different resources from external assemblies like controls, images, styles etc.

Here id the full source code.
