The Webbrowser control provides us with the “ProgressChanged” event. We can use the “CurrentProgress” and “MaximumProgress” Properties of the WEbBrowserProgressChangedEventArgs in this method to determine the percentage of the page that is downloaded.
Drag and drop a Progressbar. Leave the name set to its default (progressbar1). Add an event handler to the Webbrowser’s ProgressChanged event.
private void webBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e) { progressBar1.Maximum = Convert.ToInt32( e.MaximumProgress); progressBar1.Value = Convert.ToInt32( e.CurrentProgress); }
