AzureTrafficIncidentResult Class

Contains a traffic incident information response obtained from the Azure Maps service.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v24.2.dll

#Declaration

public class AzureTrafficIncidentResult

#Remarks

After you obtain a list of incidents in the RequestTrafficIncidents method, the provider raises the TrafficIncidentCalculated event. You can handle the event to access the collection of received incidents or add custom logic.

This example obtains a list of incidents in the specified area from the Azure Maps service and displays information about obtained incidents in a MemoEdit control:
