ZoomLevel control

The ZoomLevel control allows the user to zoom quickly to a particular scale in a Map. The control displays a bar with several cross-tics, each tic representing a scale level in the map. When the user clicks on a tic, the map zooms to the corresponding scale. The user can also click on the plus or minus signs to zoom to the next scale level. The ZoomLevel control buddies to one Map control on the page. You can place the control on the page where you want users to see it. It can be placed within a table or other containing control.
