BackgroundWorker.OnDoWork Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Raises the DoWork event.

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


Protected Overridable Sub OnDoWork ( _
    e As DoWorkEventArgs _
protected virtual void OnDoWork(
    DoWorkEventArgs e



Raising an event invokes the event handler through a delegate. For more information, see Events for Windows Phone 8.

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