public class ElevationsCalculatedEventArgs :
AsyncCompletedEventArgs
#Remarks
An instance of the ElevationsCalculatedEventArgs class with appropriate settings is automatically created and passed to the corresponding event’s handler.
#Example
This example demonstrates how to receive elevation information from the Bing Maps service.
To do this, request elevation information using the BingElevationDataProvider.RequestPointsElevations method. Then, display the request result using the BingElevationDataProvider.ElevationsCalculated event handler.
