Remarks
The Zoomed event occurs when the Silverlight plug-in receives a zoom input from the host. This is relevant only for hosts that support browser-initiated zooming, such as Internet Explorer 7 and later, Firefox 3, and Safari. Internet Explorer 8 on Windows 7 also supports an auto-zoom mode. For more information, see EnableAutoZoom. Initial loading also raises the Zoomed event in some cases.
Zoom is not relevant for full-screen or out-of-browser.
The Zoomed event does not have specialized event data (for either JavaScript or managed API handling). For managed handling, you can check the value of ZoomFactor, but ZoomFactor is not available for JavaScript handling.
