WebBrowser.ProgressChanged Event

Occurs when the WebBrowser control has updated information on the download progress of a document it is navigating to.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

member ProgressChanged : IEvent<WebBrowserProgressChangedEventHandler,
    WebBrowserProgressChangedEventArgs>

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.

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ProgressChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type WebBrowser named WebBrowser1. Then ensure that the event handler is associated with the ProgressChanged event.
