BindingList<T>.OnAddingNew(AddingNewEventArgs) Method


Raises the AddingNew event.

 virtual void OnAddingNew(System::ComponentModel::AddingNewEventArgs ^ e);
protected virtual void OnAddingNew (System.ComponentModel.AddingNewEventArgs e);
abstract member OnAddingNew : System.ComponentModel.AddingNewEventArgs -> unit
override this.OnAddingNew : System.ComponentModel.AddingNewEventArgs -> unit
Protected Overridable Sub OnAddingNew (e As AddingNewEventArgs)



An AddingNewEventArgs that contains the event data.


The AddingNew event and the AddNew method allow custom-created items to be added to the list.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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