Updates the visible cells when an item in the Items collection has changed.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

protected:
virtual void OnItemsChanged(
	Object^ sender,
	ItemsChangedEventArgs^ args
) override

Parameters

sender
Type: System::Object^

The object that raised the ItemsChanged event.

args
Type: System.Windows.Controls.Primitives::ItemsChangedEventArgs^

The data for the event.

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

The OnItemsChanged 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 OnItemsChanged in a derived class, make sure that you call the base class’s OnItemsChanged method so that registered delegates receive the event.
