Calculated route

To accomplish this, do the following:

View Example

<dxm:InformationLayer EnableHighlighting="False">
    <dxm:InformationLayer.DataProvider>
        <dxm:BingRouteDataProvider x:Name="routeProvider" 
                                   BingKey="{Binding Source={StaticResource YourBingKey}}"
                                   LayerItemsGenerating="routeProvider_LayerItemsGenerating"/>
    </dxm:InformationLayer.DataProvider>
</dxm:InformationLayer>
public partial class MainWindow : Window {

    public MainWindow() {
        InitializeComponent();

        // Create three waypoints and add them to a route waypoints list. 
        List<RouteWaypoint> waypoints = new List<RouteWaypoint>();
        waypoints.Add(new RouteWaypoint("New York", new GeoPoint(41.145556, -73.995)));
        waypoints.Add(new RouteWaypoint("Oklahoma", new GeoPoint(36.131389, -95.937222)));
        waypoints.Add(new RouteWaypoint("Las Vegas", new GeoPoint(36.175, -115.136389)));

        routeProvider.CalculateRoute(waypoints);
    }

    private void routeProvider_LayerItemsGenerating(object sender, LayerItemsGeneratingEventArgs args) {
        char letter = 'A';
        foreach (MapItem item in args.Items) {
            MapPushpin pushpin = item as MapPushpin;
            if (pushpin != null)
                pushpin.Text = letter++.ToString();
            MapPolyline line = item as MapPolyline;
            if (line != null) {
                line.Fill = Brushes.Red;
                line.Stroke = Brushes.Red;
            }
        }

        map.ZoomToFit(args.Items);
    }
