Assembly:  geobase.net (in geobase.net.dll) Version: 4.97.0.0
Syntax
public delegate void NotificationDelegate(

)

Type: Telogis.GeoBase.NavigationNavigationEvent

Remarks
Examples
A delegate has the following structure:
C#
private void myNotificationDelegate(object sender, NavigationEvent e)
{
    // do something useful
}
The delegate is passed the corresponding NavigationEvent. This object may be used to retrieve the target street name, turn direction and other such information:
C#
private void UpcomingTurn(object sender, NavigationEvent e)
{
    Console.WriteLine("Turn into " + e.TargetStreet);
}
Finally, the delegate may be used in conjunction with an event, such as a BeforeTurnDistanceNotification:
C#
myNavigator.AddNotification(new BeforeTurnDistanceNotification(100, 0, DistanceUnit.METERS, new NotificationDelegate(UpcomingTurn)));
This is a notification that fires no earlier than 100 meters before every turn. The notification, when fired, will call our UpcomingTurn function and output "Turn into (street name)" to the console.
