Notifications on Secondary Tiles in windows phone 7:

in this blog am going explain you about update the secondary tile from the notification service

Since 256-MB Windows Phone Devices fully support Push Notifications, it is possible to change the Secondary Tile content with a little extra effort. In this episode of EvenTiles we will take a look at adding Tile Notifications to the application. Those Tile Notifications are delivered to individual Windows Phone devices through the Microsoft Push Notification Service, just like all other Push Notifications.
In this blog entry we will concentrate on the client side, mainly providing code that registers the application. To test the application, we will make use of a little ASP.NET application that is based on the sample that is introduced in the How to Send and Receive Tile Notifications for Windows Phone article. It is beyond the scope of this blog entry to show how to host a web service (for instance by making use of Azure functionality).

NOTE: The ASP.NET test application cannot be created using Visual Studio 2010 Express for Windows Phone. You either need at least Visual Studio 2010 Professional or the free Visual Web Developer 2010 Expressto create the test application.

Push Notifications on Secondary Tiles

Something that is not entirely clear in the referred How to article, or in the documentation around Push Notifications on MSDN is the fact that sending Tile Updates through Push Notifications is not limited to the Application Tile, but you can also use the same approach to update Secondary Tiles. Since we are dealing with a Secondary Tile in the EvenTiles application, we will focus on updating a Secondary Tile. In the ASP.NET test application we will create the following message to update our tile:

Updating a Seondary Tile

1. // Create the Tile message.
2. string tileMessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
3. "<wp:Notification xmlns:wp=\"WPNotification\">" +
4.     "<wp:Tile ID=\"/MainPage.xaml?TileId=Secondary\">" +
5.       "<wp:BackContent>" + TextBoxBackContent.Text + "</wp:BackContent>" +
6.       "<wp:Count>" + nrRuns.ToString() + "</wp:Count>" +
7.    "</wp:Tile> " +
8. "</wp:Notification>";

By explicitly specifying the ID of a tile you can inform the Push Notification Service that you want to update a specific (Secondary) Tile. Omitting the ID passes the update to the Application Tile. Since EvenTiles creates the Secondary Tile as shown below, passing the Tile Notification message as shown above will update the Secondary Tile if it is pinned to the Start Screen. In the sample we only update the BackContent of the Secondary Tile and the count on the front of it, but it is possible to update more properties of the Secondary Tile. Of course it is important to use the same URI for the Secondary Live Tile when updating it through a Tile Notification.

Creating a Secondary Tile

1. private void btnInstall_Click(object sender, RoutedEventArgs e)
2. {
3.     StandardTileData NewTileData = new StandardTileData
4.     {
5.         BackgroundImage = new Uri("Background.png", UriKind.Relative),
6.         Title = "EvenTiles",
7.         Count = 0,
8.         BackBackgroundImage = new Uri("BackBackTile.png", UriKind.Relative),
9.         BackTitle = "EvenTiles",
10.         BackContent = App.ActualSecBackContent
11.     };
12.     ShellTile.Create(new Uri("/MainPage.xaml?TileId=Secondary", UriKind.Relative), NewTileData);
13. }

In order to receive Tile Notifications in EvenTiles, the application needs to create aHttpNotificationChannel or attach to an already created channel if the application is started again on a particular Windows Phone device. The following code snippet shows how to setup a new notification channel. If the channel is successfully opened, it will pass a URI through the ChannelUriUpdated event handler. This URI is used to send notifications to the particular Windows Phone Device that received this URI from the Push Notification Service. This URI is unique for the application and the phone on which the application is running. If the channel already exists, this method simply starts listening for channel changes or errors through the ChannelUriUpdated and ErrorOccurred events respectively.

Getting a Notification Channel

1. public class TileNotifications
2. {
3.     public const string tileNotificationChannel = "EvenTilesChannel";
4.  
5.     public void SetupChannel()
6.     {
7.         var pushChannel = HttpNotificationChannel.Find(tileNotificationChannel);
8.         if (pushChannel == null)
9.         {
10.             pushChannel = new HttpNotificationChannel(tileNotificationChannel);
11.             pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
12.             pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);
13.             pushChannel.Open();
14.             pushChannel.BindToShellTile();
15.         }
16.         else
17.         {
18.             pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
19.             pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);
20.  
21.             // Display the URI for testing purposes. Normally, the URI would be passed back to a web service.
22.             System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
23.         }
24.     }

If you want to send out push notifications from a web service, the Windows Phone application typically would send this URI to a web service, that in turn uses it to deliver the push notifications to the registered device. In our test application we simply display the URI in the debug windows of Visual Studio to be able to copy it to our ASP.NET test application.
If you are no longer interested in receiving Tile Notifications for your application, you can close a previously opened HttpNotificationChannel, make sure to dispose of it and also make sure to unsubscribe to events to prevent against leaking memory. The following code snippet shows how you can stop receiving Tile Notifications:

Closing a Notification Channel

1. public void CloseChannel()
2. {
3.     var pushChannel = HttpNotificationChannel.Find(tileNotificationChannel);
4.     if (pushChannel != null)
5.     {
6.         pushChannel.ChannelUriUpdated -= PushChannel_ChannelUriUpdated;
7.         pushChannel.ErrorOccurred -= PushChannel_ErrorOccurred;
8.         pushChannel.Close();
9.         pushChannel.Dispose();
10.         App.GetLiveTileNotifications = false;
11.     }
12. }

Finally, in our EvenTiles application we implement some simplified event handling to react on push channel changes and errors. This implementation is for demonstration purposes only and can be used to manually pass a channel URI to an ASP.NET application or to close down / reinitialize the push channel on certain errors. The following code snippet shows how we simply write the channel URI to the Output Window of Visual Studio.

Handling Push Channel Events

1. void PushChannel_ErrorOccurred(object sender, NotificationChannelErrorEventArgs e)
2. {
3.     switch (e.ErrorType)
4.     {
5.         case ChannelErrorType.ChannelOpenFailed:
6.             App.GetLiveTileNotifications = false;
7.             break;
8.         case ChannelErrorType.PayloadFormatError:
9.             SetupChannel();
10.             break;
11.         default:
12.             CloseChannel();
13.             break;
14.     }
15. }
16.  
17. void PushChannel_ChannelUriUpdated(object sender, NotificationChannelUriEventArgs e)
18. {
19.     System.Diagnostics.Debug.WriteLine(e.ChannelUri.ToString());
20.     App.GetLiveTileNotifications = true;
21. }

To send Tile Notifications to EvenTiles, make sure to run EvenTiles and enable Tile Notifications through the Settings Page. Once Tile Notifications are enabled, you can copy the channel URI from the Visual Studio Output Window and paste it in the ASP.NET test application. After this step, you can send tile updates to EvenTiles.

The ASP.NET test application does so in aThreadPool thread. You can specify the number of updates and the time between updates. Each time another update is send, the count property that will be displayed on the front side of the Secondary Tile that EvenTiles pinned on the start screen will be updated.
Even though Background Agents are not supported on 256-MB devices, we have a nice workaround by making use of Push Notifications because they are fully supported. Of course this means that you need to invest more in server side programming, but it also means that the end user experience of a Windows Phone application can be very similar on both a 512-MB device and a 256-MB device. For this to work, the target device must have a network connection.
The complete sample code for EvenTiles so far can be downloaded here. If you want to test the application on a 256-MB device (emulator), you will need to download and install the Windows Phone 7.1.1 SDK Update as well. The ASP.NET test application is also available as a separate download. In order to run this test application, you need a version of Visual Studio 2010 that supports creating  and debugging ASP.NET applications.
The following video shows how to subscribe to Tile Notifications from within the EvenTiles application and how to test the newly added functionality by means of an APS.NET test application.

Getting started with Tile Notifitcation in Windows Phone 7

• Count - Also we call this as Badge, is an integer value between 0 to 99. We can specify the count as per the requirement which can be updated on the notifications
• Background Image - An image property which will display the images as the background for the tile.
• Title - Title of the application which should normally be with in 15 characters, exceeding the 15 characters will be truncated automatically.
