APP Bar Overview

The App Bar (Application toolbar) in the Windows 8 store application plays the same role as AppBar in Windows Phone. We can provide users with a variety of operating interfaces, to achieve navigation or trigger commands.

AppBar is generally hidden by default, or it can be set to always be visible. We can display AppBar by sweeping the top or bottom edges of the screen, AppBar is hidden after being clicked or lost focus, of course we can also control appbar display or hide programmatically.

The Windows 8 store application typically contains two appbar:

1) Bottom AppBar

The bottom appbar is usually used to trigger the command, and the Global command is on the right, and the context command is on the left. When an item of a context command is selected, it can be invoked programmatically. If you have a single common command, you can place it on the canvas. Menu pop-up can be used to display the related command groups.

2) Top of AppBar

The top appbar is used for navigation in immersed view, such as adding a return button or caption, and can also be used to toggle between pages or views.
