Windows 8 Apps provide a frames feature for navigation among pages in the single application. You can create multiple pages for your Windows 8 Apps and support the user navigating among the pages within the app. In Metro apps navigation will be implemented with the help of a navigate method of the frame class.

The Navigate function has two overloaded methods; the first one takes one argument that is the name of the page we want to navigate and the other overloaded method takes two arguments; one is the name of the page and the second is the parameter of the object type that we want to pass during navigation.

Today we are going to use the second overloaded method of the navigate function that takes two arguments.

In this artilce we are going to learn how to pass multiple values among pages on navigation in an application in Windows 8 Apps.

Here we design two pages. We fill the information on first page and navigate to second page, then the second page will show all information that are fill in the first page.

Steps to followed:

Step 1 First, we will create a new blank Windows Store Application.

Open Visual Studio 2012.
File -> New -> Project
Choose Template -> Visual C# ->Windows Store
Select Blank Application
Rename the application.

Step 2 In the MainPage.xaml file we design a form to be filled in by the user:

<Page

x:Class="App9.MainPage"

IsTabStop="false"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:App9"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d">

<Grid.Background>

</LinearGradientBrush>

</Grid.Background>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

</Grid>

</Page>

Step 3 In this step we add a page to an app that supports navigation:

Select Project > Add New Item. The Add New Item dialog box opens.
Pick the Windows Metro style template type.
In the center pane, select Basic Page.
Click Add.

Step 4 The BlankPage1.xaml file is as in the following code:

<Page

x:Class="App9.BlankPage1"

IsTabStop="false"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:App9"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d" Loaded="Page_Loaded_1">

<Grid.Background>

</LinearGradientBrush>

</Grid.Background>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

</Grid>

</Page>

Step 5 Here we define a class that has three properties.

public class show
{

public string name

{

get;

set;
}

public string desig

{

get;

set;
}

public int sal

{

get;

set;

}

}

Step 6 The MainPage.xaml.cs file is as in the following code:

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

private void myclick(object sender, RoutedEventArgs e)

{

show s = new show() { name = name.Text, desig = desig.Text, sal = int.Parse(sal.Text) };

this.Frame.Navigate(typeof(BlankPage1), s);
}

}

In the above code we create an object of a class that we have created in step 5 and set the value of its properties. Then, we naviagate to BlankPage1 with the navigate method and pass that object as a parameter in this function.

Step 7 The code of the BlankPage1.xaml.cs file:

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

namespace App9

{

public sealed partial class BlankPage1 : Page

{

public BlankPage1()

{

this.InitializeComponent();

}

protected override void OnNavigatedTo(NavigationEventArgs e)

{

show s =(show) e.Parameter;

name.Text = "Your Name is: "+ s.name;

desig.Text = "your Designation is: "+ s.desig;

sal.Text = "Your Salary is: "+ s.sal.ToString();

}

private void Page_Loaded_1(object sender, RoutedEventArgs e)

{

}

}

In the above code we get a parameter through parameter properties and typecast it with the class name. Now, we show the value of the peroperties in the textblocks of BlankPage1.

Step 8 Press F5 to see the output. Fill in the form and click on the submit button:

You will see the information entered into page1 on page2:
