VEMap.SetZoomLevel Method

You are not viewing the latest version of the AJAX control. Bing Maps AJAX V7 is the recommended JavaScript control for Bing Maps. If you need this documentation, it is available in as a CHM or PDF download.

Sets the view of the map to the specified zoom level.



Parameter Description


The zoom level for the map. Valid values range from 1 through 19

Higher zoom levels show more detail on the map, and you appear closer to the ground.

Some areas do not have high-resolution aerial photography and therefore may not support the highest zoom levels.

If you are setting both the center point and the zoom level, you should use the VEMap.SetCenterAndZoom Method, rather than calling the VEMap.SetCenter Method and the SetZoomLevel method separately.
