Introduction

In most cases during the launch of an application, you need to do some background operations such as making web request, parsing some data or something else and while doing this in background it is necessary to keep the user engaged by showing splash screen.
This article helps you to create splash screen from XAML page and display it as soon as your application launches, and show it until your background activity finishes. The advantage of this approach rather than popup approach is that you can dynamically set start up or next page depending on the result of your background activity.

Necessary steps

  1. First create a Windows phone Project in visual studio.
  2. Delete default splash screen image from project.
  3. Your project already contains MainPage.xaml file, keep it as it is. Add a new Page named SplashPage.xaml in the project, replace the existing xaml file code with following code.
<phone:PhoneApplicationPage
x:Class="WindowsPhoneSample5.SplashPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
SupportedOrientations="Portrait" Orientation="Portrait"
mc:Ignorable="d"
shell:SystemTray.IsVisible="False">
 
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Transparent">
<Image Source="/splash.jpg" Stretch="Fill"/>
</Grid>
 
</phone:PhoneApplicationPage>

Make sure to set shell:SystemTray.IsVisible to False for using the full screen to display the image.

Modifying SplashPage.cs

Now, edit SplashPage.cs file

  1. Handle the Loaded Event of SplashPage - SplashPage_Loaded, as shown below,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
using System.IO;
 
namespace WindowsPhoneSample5
{
public partial class SplashPage : PhoneApplicationPage
{
private HttpWebRequest request;
 
public SplashPage()
{
InitializeComponent();
Loaded += SplashPage_Loaded;
}
 
void SplashPage_Loaded(object sender, RoutedEventArgs e)
{
request = (HttpWebRequest)HttpWebRequest.Create(new Uri("http://www.developer.nokia.com/Community/Wiki/Portal:Windows_Phone_UI_Articles"));
request.BeginGetResponse(new AsyncCallback(ReceiveResponseCallBack), null);
}
 
private void ReceiveResponseCallBack(IAsyncResult result)
{
HttpWebResponse response = (HttpWebResponse)this.request.EndGetResponse(result);
using (var stream = response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(stream))
{
string str = reader.ReadToEnd();
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
});
}
}
}
}
}

Please note that SplashPage_Loaded function merely makes an asynchronous HTTP request, and ReceiveResponseCallBack is called when the HTTP request returns a response. On receiving a response, the user is navigated to MainPage.xaml. deployment.Current.Dispatcher.BeginInvoke is used to access UI thread. Thus in the function, you may add code to perform any necessary background tasks while the splash screen is shown to the user.

Modifying MainPage.xaml.cs

From SplashPage the user is navigated to MainPage. Once the MainPage is loaded we should remove the stack entry of the SplashPage from back stack. This is done so that SplashScreen isn't considered as a page and the user doesn't navigate back to it by using the back key. To do this we need to modify the file MainPage.xaml.cs as follows.

namespace WindowsPhoneSample5
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
Loaded += MainPage_Loaded;
}
 
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
NavigationService.RemoveBackEntry();
}
 
}
}

ModifyingWMAppManifest

The last step is to add SplashPage.xaml in the Navigation Page tab of WMAppManifest.xml file. This is done so that the user is shown the splash screen when the application is launched.

This article illustrated how you can develop a custom splash screen page for your Windows Phone application. There are other approaches to create a custom splash screen too, please refer to the see also section for related articles.
