BackgroundWorker.OnProgressChanged Method

Raises the ProgressChanged event.

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

protected virtual void OnProgressChanged(
	ProgressChangedEventArgs e
)

Parameters

e
Type: System.ComponentModel.ProgressChangedEventArgs
A ProgressChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Events Overview for Silverlight.

The OnProgressChanged 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 OnProgressChanged in a derived class, be sure to call the base class’s OnProgressChanged method so that registered delegates receive the event.
