The following properties accept/return BingTravelMode values:
Remarks
The values listed by the BingTravelMode enumeration are used to set the BingRouteOptions.Mode property.
Example
This example demonstrates how to calculate routes to the destination point from major roads. For this do the following.
- To calculate routes from major roads the BingRouteDataProvider.CalculateRoutesFromMajorRoads method should be called. In this example it is called in the Calculate Routes From Major Roads button click event handler.
- To process request result the BingRouteDataProvider.RouteCalculated event should be handled. The requested results contain the total distance of a route, itinerary item (BingRouteResult.Distance, BingRouteLeg.Distance, BingItineraryItem.Distance), the time required to follow the calculated route (BingRouteResult.Time) and pass the route leg and itinerary item (BingRouteLeg.Time, BingItineraryItem.Time). You can also see the maneuvers associated with the itinerary item (BingItineraryItem.Maneuver) and other parameters.
- To customize map items generated by the BingRouteDataProvider object (because the InformationDataProviderBase.GenerateLayerItems property value is true by default) the InformationDataProviderBase.LayerItemsGenerating event should be handled.
