'Declaration
Public Event UploadDataCompleted As UploadDataCompletedEventHandler

This event is raised each time an asynchronous data upload operation completes. Asynchronous data uploads are started by calling the UploadDataAsync methods.

The UploadDataCompletedEventHandler is the delegate for this event. The UploadDataCompletedEventArgs class provides the event handler with event data.

For more information about handling events, see Consuming Events.

The following code example demonstrates setting an event handler for this event.

		Public Shared Sub UploadDataInBackground3(ByVal address As String)

			Dim client As WebClient = New WebClient()
			Dim text As String = "Time = 12:00am temperature = 50" 
			Dim data() As Byte = System.Text.Encoding.UTF8.GetBytes(text)
			AddHandler client.UploadDataCompleted, AddressOf UploadDataCallback3
                        Dim uri as Uri = New Uri(address)
			client.UploadDataAsync(uri, data)
		End Sub
