)

'Usage

Parameters

e: An AnnBeforeObjectChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnBeforeObjectChanged 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 OnBeforeObjectChanged in a derived class, be sure to call the base class's OnBeforeObjectChanged method so that registered delegates receive the event.

Example
