BindingContext.OnCollectionChanged(CollectionChangeEventArgs) Method

Definition

Raises the CollectionChanged event.

protected:
 virtual void OnCollectionChanged(System::ComponentModel::CollectionChangeEventArgs ^ ccevent);
protected virtual void OnCollectionChanged (System.ComponentModel.CollectionChangeEventArgs ccevent);
abstract member OnCollectionChanged : System.ComponentModel.CollectionChangeEventArgs -> unit
override this.OnCollectionChanged : System.ComponentModel.CollectionChangeEventArgs -> unit
Protected Overridable Sub OnCollectionChanged (ccevent As CollectionChangeEventArgs)

Parameters

ccevent
CollectionChangeEventArgs

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