OnDownloadProgressChanged Method

WebClient.OnDownloadProgressChanged Method

Raises the DownloadProgressChanged event.

Namespace:  System.Net
Assembly:  System.Net (in System.Net.dll)

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.
