    #Example

    #How to: Obtain and Display a List of Traffic Incidents

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

    A traffic incident map

    • Create an InformationLayer object and add it to the MapControl.Layers collection.

    • Initialize the layer’s DataProvider property with a BingTrafficIncidentDataProvider object.

    • Specify the provider’s BingKey property.

    • Call the provider’s RequestTrafficIncidents method to receive a list of incidents.

    • Handle the BingTrafficIncidentDataProvider.TrafficIncidentCalculated event to access the list of incidents and display incident-related information in a MemoEdit control.
