Examples

The following example code uses the BadgeNotification method to create a numeric badge notification. If you used this method to set the value to "0", it would clear the badge.

var Notifications = Windows.UI.Notifications;

var badgeXml = Notifications.BadgeUpdateManager.getTemplateContent(Notifications.BadgeTemplateType.badgeNumber);
var badgeAttributes = badgeXml.getElementsByTagName("badge");
badgeAttributes[0].setAttribute("value", "26");

// Create a badge notification from XML
var badgeNotification = new Notifications.badgeNotification(badgeXml);

The following example code uses the BadgeNotification method to create a glyph badge notification. If you used this method to set the value to "none", it would clear the badge.

var Notifications = Windows.UI.Notifications;

var badgeXml = Notifications.BadgeUpdateManager.getTemplateContent(Notifications.BadgeTemplateType.badgeNumber);
var badgeAttributes = badgeXml.getElementsByTagName("badge");
badgeAttributes[0].setAttribute("value", "alert");

// Create a badge notification from XML
var badgeNotification = new Notifications.badgeNotification(badgeXml);

Constructors

BadgeNotification(XmlDocument)

Creates and initializes a new instance of the BadgeNotification.

Properties

Content	Gets the XML that defines the value or glyph used as the tile's badge.
ExpirationTime	Gets or sets the time that Windows will remove the badge from the tile. By default, local badge notifications do not expire and push, periodic, and scheduled badge notifications expire after three days. It is a best practice to explicitly set an expiration time to avoid stale content.
