web services - C# Async WebService

谁能给我一个例子，如何使用的方法开始显示一个警告用户说加载…使用下面的代码，我使用Completed事件放置查询，使用Begin?

service.EventosDoDiaCompleted += RecebeEventos;
service.EventosDoDiaAsync();
private void RecebeEventos(object sender, AsyncCompletedEventArgs e)
{
   Dataset ds = service.EventosDoDia();
}

放置简单的Textblock或类似的东西:

    service.EventosDoDiaCompleted += RecebeEventos;
    textblock.Text="Loading....";
    service.EventosDoDiaAsync();
    private void RecebeEventos(object sender, AsyncCompletedEventArgs e)
    {
        textblock.Text="Loaded";
        Dataset ds = service.EventosDoDia();
    }
