protected:
override void OnItemsChanged(System::Object ^ sender, System::Windows::Controls::Primitives::ItemsChangedEventArgs ^ args);
protected override void OnItemsChanged (object sender, System.Windows.Controls.Primitives.ItemsChangedEventArgs args);
override this.OnItemsChanged : obj * System.Windows.Controls.Primitives.ItemsChangedEventArgs -> unit
Protected Overrides Sub OnItemsChanged (sender As Object, args As ItemsChangedEventArgs)
Parameters
- sender
- Object
The object that raised the ItemsChanged event.
The data for the event.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
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(Object, ItemsChangedEventArgs) in a derived class, make sure that you call the base class' OnItemsChanged(Object, ItemsChangedEventArgs) method so that registered delegates receive the event.
