BindingsCollection.OnCollectionChanged Method

Raises the CollectionChanged event.

[Visual Basic]
Protected Overridable Sub OnCollectionChanged( _
   ByVal ccevent As CollectionChangeEventArgs _
protected virtual void OnCollectionChanged(
 CollectionChangeEventArgs ccevent
protected: virtual void OnCollectionChanged(
 CollectionChangeEventArgs* ccevent
protected function OnCollectionChanged(
   ccevent : CollectionChangeEventArgs


A CollectionChangeEventArgs that contains the event data.


Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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