Question

I use in my application ScheduledTileNotifications and push 10 until 20 messages in the TileUpdateManager. But on the metro there are only 5 messages active. What can I do to display more than 5 notifications in the metro-Tile?

string tileXmlString = "<tile>"
       + "<visual>"
       + "<binding template='TileWideSmallImageAndText03' branding='name'>"
       + "<image id='1' src='ms-appx:///Assets/icons/cube_for_kachel.png'/>"
       + "<text id='1'>" + longSubject + "\n" + message.title + "</text>"
       + "</binding>"
       + "<binding template='TileSquareText04' branding='name'>"
       + "<text id='1'>" + shortSubject + "\n" + message.title + "</text>"
       + "</binding>"
       + "</visual>"
       + "</tile>";

XmlDocument tileXml = new XmlDocument();
tileXml.LoadXml(tileXmlString);
ScheduledTileNotification sceduleNotification = new ScheduledTileNotification(tileXml, DateTime.Now.AddSeconds(15));
TileUpdateManager.CreateTileUpdaterForApplication().EnableNotificationQueue(true);
TileUpdateManager.CreateTileUpdaterForApplication().AddToSchedule(sceduleNotification);

When I set the EnableNotificationQueue to true, five of my notification run in a circle. When I set it to false, my notification don´t run in a circle. But I have 10 until 20 Notifications, which should run in a circle. Do you think it is possible.

When I use the AddToSchedule method an push 10 Notifications, each notification will show for one time.

The problem is related to the use of the EnableNotificationQueue method. In fact, as you can read at http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.notifications.tileupdater.enablenotificationqueue:

When queuing is enabled, a maximum of five tile notifications can
automatically cycle on the tile.

Try to pass false to this method.

According to the documentation, you can schedule up to 4096 notifications. Reref to http://hansstan.wordpress.com/2012/09/02/windows-8-advanced-tile-badge-topics/ for a working example.
