AzureTrafficIncidentResult Class
In This Article
Contains a traffic incident information response obtained from the Azure Maps service.
Namespace: DevExpress.XtraMap
Assembly: DevExpress.XtraMap.v24.2.dll
#Declaration
#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:
using DevExpress.XtraMap;
using System.Text;
// ...
const string key = "your key";
AzureTrafficIncidentDataProvider trafficIncidentProvider;
// ...
public Form1() {
InitializeComponent();
trafficIncidentProvider = new AzureTrafficIncidentDataProvider {
AzureKey = key
};
imageLayer2.DataProvider = new AzureMapDataProvider() {
AzureKey = key,
Tileset = AzureTileset.BaseHybridRoad
};
imageLayer1.DataProvider = new AzureMapDataProvider() {
AzureKey = key,
Tileset = AzureTileset.Imagery,
};
informationLayer1.DataProvider = trafficIncidentProvider;
informationLayer1.DataRequestCompleted += OnDataRequestCompleted;
trafficIncidentProvider.TrafficIncidentCalculated += OnTrafficIncidentCalculated;
trafficIncidentProvider.RequestTrafficIncidents(new SearchBoundingBox(-115.338457, 36.268745,
-114.988268, 36.1010376), 18, -1,
new AzureTrafficIncidentOptions {
OriginalPosition = false,
IncidentGeometryType = AzureTrafficIncidentGeometryType.Shifted
});
}
void OnDataRequestCompleted(object sender, RequestCompletedEventArgs e) {
mapControl1.ZoomToFitLayerItems();
}
private void OnTrafficIncidentCalculated(object sender, AzureTrafficIncidentCalculatedEventArgs e) {
if (e.Cancelled) return;
if (e.RequestResult.ResultCode != RequestResultCode.Success) {
memoEdit1.Text = "Traffic incidents were not found for this area.";
return;
}
StringBuilder resultList = new StringBuilder("");
int resCounter = 1;
foreach (AzureTrafficIncidentResult resultInfo in e.RequestResult.IncidentResults) {
resultList.Append(string.Format("Incident {0}: \r\n", resCounter));
resultList.Append(string.Format("Cause: {0}\r\n", resultInfo.Cause));
resultList.Append(string.Format("Description: {0}\r\n", resultInfo.Description));
resultList.Append(string.Format("Start Time: {0}\r\n", resultInfo.StartDate));
resultList.Append(string.Format("End Time: {0}\r\n", resultInfo.EndDate));
resultList.Append(string.Format("Lat: {0}, Lon: {1}\r\n", resultInfo.Point.Latitude, resultInfo.Point.Longitude));
resultList.Append(string.Format("_______________________\r\n"));
resCounter++;
}
memoEdit1.Text = resultList.ToString();
