Introduction to Silver Light 3.0 Navigation

Objective

In this article , I will show how to work with Silver Light Navigation framework. Create a Silver Light Application by selecting Silver Light application from project template. And follow below steps.

Step 1 :Adding references

Add below references to Silver Light application.

System.Windows.Control
System.Windos.Control.Data
System.Windows.Control.Navigation

Step 2: Adding namespaces

Open MainPage.Xaml and add the namespace. Give name of the namespace as Navigation and add System.Windows.Control.Navigation. See the image below.

Step 3 Creating Silver Light Page for navigation

Now I am constructing the pages to navigate. Right click on silver light project and add a new folder. You can give any name to folder of your choice. I am giving name here View. Add two silver light pages inside this folder. To add right click on folder and add new Item then select Silver Light page. Page I am adding is  

1. Image.Xaml
2. Me.Xaml

Me.Xaml
1. Title of the page can be amending in Title tag. See the tag in bold.
2. New added Silver Light page is navigation page.
3. I have added a simple text block with some static text on the page for the demo purpose. 

<navigation:Page x:Class="NavigationSample1.Views.Me"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d=http://schemas.microsoft.com/expression/blend/2008xmlns:mc=http://schemas.openxmlformats.org/markup-compatibility/2006mc:Ignorable="d"xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"d:DesignWidth="640" d:DesignHeight="480"Title="This Page is About Me"><Grid x:Name="LayoutRoot"><TextBlock Text="This Site is about me " FontSize="100" VerticalAlignment="Center" Foreground="Red" /></Grid></navigation:Page>

Image.Xaml
1. Title of the page can be amending in Title tag. See the tag in bold.
2. New added Silver Light page is navigation page.
3. One image is added for the demo purpose.

<navigation:Page x:Class="NavigationSample1.Views.Image"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d=http://schemas.microsoft.com/expression/blend/2008xmlns:mc=http://schemas.openxmlformats.org/markup-compatibility/2006mc:Ignorable="d"xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"d:DesignWidth="640" d:DesignHeight="480"Title="My Image"><Grid x:Name="LayoutRoot"><Image Height="auto" Width="auto" Source="a.jpg" /></Grid></navigation:Page>

Step 4 : Designing for navigation

Now it is time to design main page for navigation.
1. I am adding two HyperLinkButtons. On clicking of buttons, we will navigate to other pages.
2. There is TAG property of hyperlink, which says where hyperlink will navigate. Views are folder we added and Me.Xaml is silver light page to navigate.

Tag="/Views/Me.Xaml" 

3. Add either a frame or page to where navigated page will be open. There are two options either Page or Frame. Navigation is the name of the namespace we added. See the image below. 

4. Navigation framework can have many properties. I am setting few of them. See below.

<Navigation:Frame x:Name="MyFrame" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="20" />

MainPage.Xaml

<UserControl x:Class="NavigationSample1.MainPage"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x=http://schemas.microsoft.com/winfx/2006/xamlxmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:Navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480"><Grid x:Name="LayoutRoot" Width="auto" Height="auto" Background="Wheat" ><StackPanel Orientation="Horizontal" VerticalAlignment="Top" ><StackPanel Orientation="Vertical" Width=" 250"><HyperlinkButton x:Name="btnAbt" Tag="/Views/Me.Xaml" Content="About Me" FontSize="24" /><HyperlinkButtonx:Name="btnImg" Tag="/Views/Image.Xaml" Content="My Images" FontSize="24" /></StackPanel><Navigation:Frame x:Name="MyFrame" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="20" /></StackPanel></Grid></UserControl>

Step 5 : Writing code behind to navigate

1. Add click event to hyperlinkbuttons.

btnAbt.Click += new RoutedEventHandler(NavigateToLink);
btnImg.Click  +=new RoutedEventHandler(NavigateToLink);

2. Handle the click event

void NavigateToLink(object sender, RoutedEventArgs e)
{
      HyperlinkButton buttonToNavigate = sender as HyperlinkButton;string urlToNavigate = buttonToNavigate.Tag.ToString();this.MyFrame.Navigate(new Uri(urlToNavigate, UriKind.Relative));
}

MainPage.Xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes; 
namespace NavigationSample1
{public partial class MainPage : UserControl
    {public MainPage()
        {
            InitializeComponent();
            btnAbt.Click += new RoutedEventHandler(NavigateToLink);
            btnImg.Click  +=new RoutedEventHandler(NavigateToLink);
        }void NavigateToLink(object sender, RoutedEventArgs e)
        {
            HyperlinkButton buttonToNavigate = sender as HyperlinkButton;string urlToNavigate = buttonToNavigate.Tag.ToString();this.MyFrame.Navigate(new Uri(urlToNavigate, UriKind.Relative));
           
        }
    }
}

Step 6 : Run the application

You can see while clicking on the hyperlinks, we are able to navigate in the frame.

So, we are able to navigate through pages using navigation framework.
