Protected Overridable Sub OnItemChanged (e As ItemChangedEventArgs)

Parameters

e: ItemChangedEventArgs

An ItemChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnItemChanged 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 OnItemChanged(ItemChangedEventArgs) in a derived class, be sure to call the base class' OnItemChanged(ItemChangedEventArgs) method so that registered delegates receive the event.
