The MapViewer User Interface
When you add a WebMapViewer control to a WebPage, it comes with widgets to manipulate the zoom, the type, and the location. The zoom level is adjusted via the Slider control on the left and you can change the location by dragging with the hand (top-left). The type of map is changed by clicking the segmented control on the top-right corner. When you change the type (for example, from Map to Satellite), a check box appears below the Segmented Control to toggle that view type. If Map is selected, a Terrain checkbox appears to show or hide terrain features; if Satellite is selected, a checkbox appears to show or hide labels.
Create and display a location on the map:
Display a location entered by the user (in the LocationField TextField) on the map:
