Create a custom event

Question

I want to create a custom event. What's the best way to do that?

Using the Pro SDK classes (like CompositePresentationEvent) or create a 'regular' .NET event?

If it's the best way to use the Pro SDK classes, could you provide me an example?

Thanks.

Kind regards,

I found it (thanks to the IlSpy disassembler!), see files below as an example of an event and eventarg class. Event-class public class GetJsonSelectionFinishedEvent : CompositePresentationEvent { public static SubscriptionToken Subscribe(Action action, bool keepSubscriberAlive = false) { return FrameworkApplication.EventAggregator.GetEvent().Register(action, keepSubscriberAlive); } public static void Unsubscribe(Action action) { FrameworkApplication.EventAggregator.GetEvent().Unregister(action); } public static void Unsubscribe(SubscriptionToken token) { FrameworkApplication.EventAggregator.GetEvent().Unregister(token); } internal static void Publish(GetJsonSelectionFinishedEventArgs activeMapViewEventArgs) { FrameworkApplication.EventAggregator.GetEvent().Broadcast(activeMapViewEventArgs); } } EventArg-class public class GetJsonSelectionFinishedEventArgs : System.EventArgs { public BasicFeatureLayer BasicFL { get; private set; } public GetJsonSelectionFinishedEventArgs(BasicFeatureLayer bfl) { this.BasicFL = bfl; } } And then you can use it just like the other available events.
