Raises the DownloadProgressChanged event.
Assembly: System.Net (in System.Net.dll)
'Declaration Protected Overridable Sub OnDownloadProgressChanged ( _ e As DownloadProgressChangedEventArgs _ )
protected virtual void OnDownloadProgressChanged( DownloadProgressChangedEventArgs e )
Classes that inherit from this class can override this method to perform additional tasks when the DownloadProgressChanged event occurs.
Raising an event invokes the event handler through a delegate.
The OnDownloadProgressChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnDownloadProgressChanged in a derived class, be sure to call the base class’s OnDownloadProgressChanged method so that registered delegates receive the event.
