Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v24.1.dll
NuGet Package: DevExpress.Wpf.Map
Declaration
Remarks
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.
Follow the steps below to create a map with traffic incidents:
Create an InformationLayer object and add it to the MapControl.Layers collection.
Create a BingTrafficIncidentDataProvider object and specify its BingKey property. Assign the object to the layer’s DataProvider property.
Call the provider’s RequestTrafficIncidents method to receive a list of incidents.
To include traffic location codes in the method’s result, enable the BingTrafficIncidentDataProvider.Options.IncludeLocationCodes property.
After you obtain a list of incidents, the provider raises the TrafficIncidentCalculated event. You can handle the event to access the collection of received incidents or add custom logic.
