BingRouteResult.BoundingBox Property

Returns the rectangular area containing the Bing resulting route.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v21.1.dll

Declaration

public SearchBoundingBox BoundingBox { get; }

Property Value

Type Description
SearchBoundingBox

A SearchBoundingBox object specifying the rectangular region.

Example

This example demonstrates how to zoom a map to the calculated route.

To do this, handle the BingRouteDataProvider.RouteCalculated event. In the event handler, using the BingRouteResult.BoundingBox property, get the top-left corner (using the SearchBoundingBox.NorthLatitude and SearchBoundingBox.WestLongitude properties) and right-bottom corner (using the SearchBoundingBox.SouthLatitude and SearchBoundingBox.EastLongitude properties) of the required region. Then, using the MapControl.ZoomToRegion method, zoom the map to the required rectangle specified by the corners.

namespace ZoomToFitOnRouteCalculated {
    public partial class Form1 : Form {
        InformationLayer Layer { get { return (InformationLayer)mapControl.Layers[1]; } }
        BingRouteDataProvider Provider { get { return (BingRouteDataProvider)Layer.DataProvider; } }

            mapControl.ZoomToRegion(new GeoPoint(bBox.NorthLatitude, bBox.WestLongitude), new GeoPoint(bBox.SouthLatitude, bBox.EastLongitude), 0.4);
            splashScreenManager.CloseWaitForm();
        }
        private void Form1_Load(object sender, System.EventArgs e) {
            Provider.RouteCalculated += OnRouteCalculated;
            Provider.CalculateRoute(new List<RouteWaypoint> {
                new RouteWaypoint("New York", new GeoPoint(41.145556, -73.995)),
