Notes

As of June 2018, Google Maps requires an API Key. You will need to set the APIKey property to your API Key in order for WebMapViewer to display any maps.

The WebMapViewer control is based on Google maps. As such, has the same strengths and limitations of Google Maps.

If errors occur during initialization of the WebMapViewer and you are running in debug mode, the error messages will appear in the IDE Messages pane.

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.

Sample Code

Create and display a location on the map:

Var location As New WebMapLocation("Fenway Park, Boston, MA")
MapViewer1.GoToLocation(location)

Display a location entered by the user (in the LocationField TextField) on the map:

MapViewer1.Search(LocationField.Value)
