Occurs when the System.Windows.Forms.WebBrowser control has updated information on the download progress of a document it is navigating to.
You can use a handler for this event to implement a navigation progress bar similar to the one in Internet Explorer. Use the WebBrowserProgressChangedEventArgs.CurrentProgress property to determine the number of bytes that have been downloaded successfully. Use the WebBrowserProgressChangedEventArgs.MaximumProgress property to determine the total number of bytes available for downloading.
