MessageBar (deprecated)

Introduction

MessageBar presents the application messages to the user. The control has a set of configurable properties:

• maxToasted: Maximum number of messages allowed to be raised at once before being announced via a single combined multi message.
• maxListed: Maximum number of messages that shall be shown at once in the drop down list. In case of a large amount of messages, a vertical scroll bar is provided.
• anchorId: Element ID upon which the MessageBar is initially positioned.
• anchorSnapPoint:begin top is set by default.

The MessageBar can then be addressed by applications via the following APIs:

• addMessages: (Array of) Messages to be raised to the user.
• deleteMessages: (Array of) Message IDs to be dropped by the user.
• deleteAllMessages: To remove all currently raised messages.

To give more examples, the MessageBar control provides also the following features:

• The MessageBar is only visible in the case that a message is raised.
• Incoming messages are displayed with some short text.
• The total count of messages raised in each priority category is displayed.

Example

In the example, click twice on the add MeliMelo button to display a message area with an error, a warning, and a success message text.
