Remarks

The app bar can be used to create modern user interfaces, similar to the ones implemented in Windows Store applications. To learn more, see the AppBar Control topic.

The app bar is used to display navigation, commands and options to end-users only when required, conserving valuable screen space. By default, the app bar is hidden from view and seamlessly appears on the screen by right clicking in the application area. The app bar disappears from view when an end-user resumes interaction with an application anywhere outside the app bar.

AppBar_Overview

Examples

The following example shows how to create an app bar containing custom regular and toggle buttons, the predefined Exit button, and the button that displays a flyout when clicked.

In this example, the AppBar control is populated with the AppBarButton and AppBarToggleButton objects, which are divided into groups using the AppBarSeparator objects. To display the predefined Exit button, the AppBar.IsExitButtonEnabled property is set to True.

The button captions are specified using the AppBarButton.Label property. The HorizontalAlignment property specifies the button alignment relative to the app bar.

The CommandButton.Glyph property is used to provide the buttons with icons from the DX Image Gallery. The glyph theming feature is enabled for all buttons and the glyph height is set using the Style declared in the app bar's Resources. You can also use the button's Content property to specify the button icons. See the Pin button — the icon for this button is specified using the Unicode symbol that corresponds to the glyph in the Segoe UI Symbol font. For more information about how to use Segoe UI Symbol icons, see Guidelines on MSDN.

The Rotate button displays the flyout when clicked. The button's Flyout property allows you associate the Flyout or MenuFlyout control with the button.

The result of the markup in this example is shown below.
