Introduction

In this project, I have explained navigation between two pages in Windows 8 app with data. Here, the most important thing is “Public Static” Keyword. I have created public static Imagesource(or “int” or “string”) reference in mainpage.xaml.cs. After that, assign to the value of the object.

I have explained simple but very useful two examples.

In the first example, I have transferred image source between one page and another page.

In the second example, I have transferred string value between one page and another page.

Using the Code

Example 1 (Transfer Imagesource)

Step 1

Open Visual Studio and create a new project. Select blank app. After that meaning full assign name. Then ok.

Step 2

Paste your four images in Asstes folder.

Step 3

After that four image control drag and drop in mainpage.xaml like this.

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">

        <Image HorizontalAlignment="Left" Height="251" Margin="88,108,0,0" 
        VerticalAlignment="Top" Width="403"/>
        <Image HorizontalAlignment="Left" Height="251"
Margin="713,123,0,0" VerticalAlignment="Top" Width="403"/>
        <Image HorizontalAlignment="Left" Height="251"
Margin="88,416,0,0" VerticalAlignment="Top" Width="403"/>
        <Image HorizontalAlignment="Left" Height="251"
Margin="713,416,0,0" VerticalAlignment="Top" Width="403"/>

    </Grid>

Step 4

After that, define the Image control name like 1^st Image control name “Image1”, 2^nd one is “Image2”, 3^rd one is “Image3” and 4th id is “Image4”.

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">

        <Image x:Name="Image1" HorizontalAlignment="Left" Height="251" 
        Margin="88,108,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image2" HorizontalAlignment="Left" Height="251"
Margin="713,123,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image3" HorizontalAlignment="Left" Height="251"
Margin="88,416,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image4" HorizontalAlignment="Left" Height="251"
Margin="713,416,0,0" VerticalAlignment="Top" Width="403"/>

    </Grid>

Step 5

After that, all images set the source and all images fire tapped event. So code looks like this:

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">

        <Image x:Name="Image1" HorizontalAlignment="Left" Height="251" Source=" Assets/1.jpg" Tapped="Image_Tapped_1"
               Margin="88,108,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image2" HorizontalAlignment="Left" Height="251" Source=" Assets/2.jpg" Tapped="Image_Tapped_2"
               Margin="713,123,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image3" HorizontalAlignment="Left" Height="251" Source=" Assets/3.jpg" Tapped="Image_Tapped_3"
               Margin="88,416,0,0" VerticalAlignment="Top" Width="403"/>
        <Image x:Name="Image4" HorizontalAlignment="Left" Height="251" Source=" Assets/4.jpg" Tapped="Image_Tapped_4"
               Margin="713,416,0,0" VerticalAlignment="Top" Width="403"/>

    </Grid>

Step 6

Create one reference of ImageSource class name ImageSource1 above of the main page contructor.

public static ImageSource ImageSource1;
public MainPage()
   {
      this.InitializeComponent();
   }

Step 7

After that project, right click add > add new item and select basic page.

Build the solution.

Step 8

After that Image_Tapped_1 event, code like this:

//
//here assign value Image1.source in "ImageSource1".and after that page
//navigation code for one page to another page.here BasicPage1 is destination page.
//
ImageSource1 = Image1.Source;
this.Frame.Navigate(typeof(BasicPage1));

Step 9

Similar to Image_Tapped_2, Image_Tapped_3, Image_Tapped_4 event, but only one change. Assign value of ImageSource1 change.

private void Image_Tapped_2(object sender, TappedRoutedEventArgs e)
{
   ImageSource1 = Image2.Source;
   this.Frame.Navigate(typeof(BasicPage1));
}

private void Image_Tapped_3(object sender, TappedRoutedEventArgs e)
{
   ImageSource1 = Image3.Source;
   this.Frame.Navigate(typeof(BasicPage1));
}

private void Image_Tapped_4(object sender, TappedRoutedEventArgs e)
{
   ImageSource1 = Image4.Source;
   this.Frame.Navigate(typeof(BasicPage1));
}

Step 10

After that, take one image control in Basicpage1.xaml and meaning full assign name like “mycatchimage”.

<Image Name="mycatchimage" HorizontalAlignment="Left" Height="193" Margin="110,40,0,0" Grid.Row="1" VerticalAlignment="Top" Width="356"/>

Step 11

Assign the source of mycatchimage in BasicPage1.xaml.cs.

public BasicPage1()
{
    this.InitializeComponent();
    mycatchimage.Source = MainPage.ImageSource1;
}

Step 12

You have run the code which is something like this:

MainPage

BasicPage1

Example 2 (Transfer String value)

Step 1

Open Visual Studio and create a new project. Select blank app. After that meaning full assign name. Then ok.

Step 2

After that one TextBox and Button control drag and drop in mainpage.xaml like this:

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <TextBox HorizontalAlignment="Left" Margin="351,172,0,0" TextWrapping="Wrap"
        Text="TextBox" VerticalAlignment="Top" Height="66" Width="412"/>
        <Button Content="Click" HorizontalAlignment="Left" 
        Margin="496,307,0,0" VerticalAlignment="Top"/>

    </Grid>

Step 3

Meaningful name of TextBox control like “myText”. And fire the button click event.

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <TextBox Name="myText" HorizontalAlignment="Left" Margin="351,172,0,0"
        TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" 
        Height="66" Width="412"/>
        <Button Content="Click" HorizontalAlignment="Left" 
        Margin="496,307,0,0"
        VerticalAlignment="Top" Click="Button_Click"/>

    </Grid>

Step 4

Create one reference of string class name “Data” above of the main page constructor.

public static string Data;
public MainPage()
{
   this.InitializeComponent();
}

Step 5

After that project, right click add > add new item and select basic page.

Build the solution.

Step 6

After that Button_Click event code like this:

private void Button_Click(object sender, RoutedEventArgs e)
{
   Data = myText.Text;
   this.Frame.Navigate(typeof(BasicPage1));
}

Step 7

After that, take one Textblock control in Basicpage1.xaml and meaning full assign name like “mycatchtext”.

<TextBlock Name="mycatchtext" HorizontalAlignment="Left" 
Margin="172,78,0,0"
Grid.Row="1" TextWrapping="Wrap" Text="TextBlock" 
VerticalAlignment="Top" Height="440" Width="815"/>

Step 8

Assign the Text of mycatchtext in BasicPage1.xaml.cs.

public BasicPage1()
{
   this.InitializeComponent();
   mycatchtext.Text = MainPage.Data;
}

Step 9

You have run the code which is something like this:

MainPage

BasicPage1
