client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged); client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
}
private void button1_Click(object sender, RoutedEventArgs e) { client.DownloadStringAsync( new Uri("http://localhost/ServicesApplication/whatever.xml"), "sample rss");
}
void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e) { if (e.UserState as string == "sample rss") { this.progressBar1.Value = e.ProgressPercentage; } }
