BackgroundWorker.OnProgressChanged Method

Raises the ProgressChanged event.
Namespace: System.ComponentModel
Assembly: System (in System.dll)
Syntax
'Declaration
Protected Overridable Sub OnProgressChanged ( _
e As ProgressChangedEventArgs _
)
protected virtual void OnProgressChanged(
ProgressChangedEventArgs e
)
Parameters

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