<NonCategorized>
Public Class SearchBoundingBox
    Inherits MapDependencyObject

The following members return SearchBoundingBox objects:

Remarks

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

Example

To send a route request, use the BingRouteDataProvider.CalculateRoute method. This method receives a list of RouteWaypoint objects as a parameter. Note that RouteWaypoint objects are created using the constructor that receives the waypoint description and a keyword that is used to search for a location on a map.
