Notifications & Metro Style apps in Windows 8: Introduction

Did you play around with the Windows Developer Preview ? If so, you did probably notice that tiles are the primary presentation of an app on the start screen.

In order to make the start screen feel vibrant and allow the user to see at a glance what’s new ( which is one of the main purposes of the metro style), you can add notifications to those tiles or use them separately.

There are three types of notifications :

Tile Notifications

Those are the information and notifications that you can see directly through the tile.

Tiles updates use pre-defined templates, and can cycle between five tiles.

Toast Notifications

“A toast notification is a transient message to the user that contains relevant, time-sensitive information and provides quick access the subject of that content in an app. It can appear whether you are in another app, the Start screen, or on the desktop. Toasts are an optional part of the app experience and are intended to be used only when your app is not the active foreground app.” Dev center – Metro style apps website

Toast notifications deliver transient messages outside the app to get the user’s attention immediately.



It’s a summary or status information concerning the app notification, on the top of the tile.

It supports square and wide tiles.

All those notifications can be :

Local notifications

  • Used only when application is running.
  • Most useful for updating tiles and badges.

Scheduled notifications

  • for toast notifications to be running at a precise time.

Push notifications

  • Update tiles, show badges and raise toasts from the cloud.
  • Work even if the application is not running.

This post is an introduction, in the coming posts I will be writing about each kind of notifications and how to implement them.

Stay tuned Smile

  1. How do you view old toasts?? I can’t seem to figure it out.
