Remarks
The SearchBoundingBox
object is specified by the SearchBoundingBox.NorthLatitude, SearchBoundingBox.EastLongitude, SearchBoundingBox.SouthLatitude and SearchBoundingBox.WestLongitude values.
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.
