Navigation using Windows Phone 7 Silverlight

This article describes how to use Navigation in Windows Phone 7. In this article we'll see how to navigate from one page to another upon the click of a button and how to send a value using a query string from one page to the other page.

Getting Started

Creating a Windows Phone Application:

  Open Visual Studio 2010.

  Go to File => New => Project

  Select Silverlight for Windows Phone from the Installed templates and choose Windows Phone Application

  Enter the Name and choose the location.


Click OK.

First of all add a new Windows phone portrait page using add new item; click and give a name for the page. My page name is Page1.xaml.

Now on the main page drag and drop a hyperlink button.

<HyperlinkButton Content="Click to redirect on next page" Height="39" HorizontalAlignment="Left" Margin="51,89,0,0" Name="hyperlinkButton1" VerticalAlignment="Top" Width="344" Click="hyperlinkButton1_Click" />

 

Click event.

private void hyperlinkButton1_Click(object sender, RoutedEventArgs e)

        {

            NavigationService.Navigate(new Uri("/Page1.xaml", UriKind.RelativeOrAbsolute));

        } 

This code will redirect you to page1 and if you want to return to the previous page then add a button control to page1 and put this on button click. 

<Button Content="Redirect To Home Page" Height="72" HorizontalAlignment="Left" Margin="31,57,0,0" Name="button1" VerticalAlignment="Top" Width="317" Click="button1_Click" /> 

private void button1_Click(object sender, RoutedEventArgs e)

        {

            NavigationService.GoBack();

        }

Now if you want to send a value from one page to another page then add this code on click event. 

private void button1_Click(object sender, RoutedEventArgs e)

        {

            NavigationService.Navigate(new Uri("/Page1.xaml?name=" + textBox1.Text, UriKind.Relative));

        } 

Call this function on Page1.xaml.

 

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)

        {

            base.OnNavigatedTo(e); 

            string name = ""

            if (NavigationContext.QueryString.TryGetValue("name", out name)) 

                textBox1.Text = name; 

        }
