System Notifications (Notification Service)
This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.
Web Parts can register to receive notifications for standard system events triggered in the browser. As the browser supports only a single callback function for events, parts should register for system events instead of trying to provide an event handler directly.
The following table lists the events that are provided automatically by the dashboard factory. The NamespaceURN for these events is urn:schemas.microsoft.com:dhtml.
