    AzureTrafficIncidentCalculationResult Class

    Contains traffic incident results received from the Microsoft Azure service.

    Namespace: DevExpress.XtraMap

    Assembly: DevExpress.XtraMap.v25.1.dll

    NuGet Package: DevExpress.Win.Map

    #Declaration

    public class AzureTrafficIncidentCalculationResult :
        RequestResultBase

    The following members return AzureTrafficIncidentCalculationResult objects:

    #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:
