Try to handle the DownloadProgressChanged and DownloadFileCompleted event.

private void button1_Click(object sender, EventArgs e)
  {
   string url = "http://framework.zend.com/releases/ZendFramework-1.11.11/ZendFramework-1.11.11.zip";
   WebClient downloader = new WebClient();
   downloader.DownloadFileCompleted += new AsyncCompletedEventHandler(downloader_DownloadFileCompleted);
   downloader.DownloadProgressChanged += new DownloadProgressChangedEventHandler(downloader_DownloadProgressChanged);
   downloader.DownloadFileAsync(new Uri(url), "C:\\temp.zip");
  }

 void downloader_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
   {
      label1.Text = e.BytesReceived + " " + e.ProgressPercentage;
    }
  void downloader_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
   {
       if (e.Error != null)
         MessageBox.Show(e.Error.Message);
       else
         MessageBox.Show("Completed!!!");
   }
