/** @delegate */ public delegate void UploadDataCompletedEventHandler ( Object sender, UploadDataCompletedEventArgs e )
The source of the event.
A UploadDataCompletedEventArgs containing event data.
When you create a UploadDataCompletedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.
