BingRouteDataProvider.CalculateRoutesFromMajorRoads(RouteWaypoint) Method

Returns driving routes to a location from major roads in four directions (West, North, East and South).

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v24.1.dll

NuGet Package: DevExpress.Wpf.Map

Declaration

public void CalculateRoutesFromMajorRoads(
    RouteWaypoint destination
)

Parameters

Name Type Description
destination RouteWaypoint

A RouteWaypoint object specifying a destination point.

Remarks

Note

This method can be used for routes in the United States, Canada and Mexico.

Example

This example demonstrates how to calculate routes to the destination point from major roads.

Important

On May 21, 2024, Microsoft announced that Bing Maps for Enterprise and its API will be discontinued. Azure Maps will be a single unified enterprise mapping platform available from Microsoft.

We are working on API compatible with Azure Maps and expect to ship it with our next major release (v24.2).

If you have an existing license to Bing Maps for Enterprise, you can continue using our existing API. You need to transition to new API until June 30, 2025 (free and basic license) or until June 30, 2028 (enterprise license).

The last date you can get a new license to Bing Maps for Enterprise is June 30, 2025. If you do not have an existing license after that date, you would not be able to use our map controls with Bing Maps or Azure Maps (until we release the new API). During that time, you can use other map providers supported by our controls, such as OpenStreetMap.

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“.
