This event is raised each time an asynchronous upload of a System.Collections.Specialized.NameValueCollection object's data completes. These uploads are started by calling the erload:System.Net.WebClient.UploadValuesAsync methods.
The System.Net.UploadValuesCompletedEventHandler is the delegate for this event. The System.Net.UploadValuesCompletedEventArgs class provides the event handler with event data.
