BingItineraryItem Class
Contains information about a single itinerary item of a Bing route.
Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v19.1.dll
Declaration
Example
This example demonstrates how to calculate routes to the destination point from major roads. To accomplish 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 the 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.
Note
Refer to How to: Get a Bing Maps Key if you run the application and see a window with the following error message: “The specified Bing Maps key is invalid. To create a developer account, refer to https://www.microsoft.com/en-us/maps/create-a-bing-maps-key“.
