BackgroundWorker.OnProgressChanged Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Raises the ProgressChanged event.
Assembly: System (in System.dll)
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 for Windows Phone 8.
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 InheritorsWhen overriding OnProgressChanged in a derived class, be sure to call the base class’s OnProgressChanged method so that registered delegates receive the event.
