BindingNavigator.OnRefreshItems Method

Definition

Raises the RefreshItems event.

protected:
 virtual void OnRefreshItems();
protected virtual void OnRefreshItems ();
abstract member OnRefreshItems : unit -> unit
override this.OnRefreshItems : unit -> unit
Protected Overridable Sub OnRefreshItems ()

Remarks

In addition to raising the corresponding RefreshItems event, the OnRefreshItems method performs the following operations against the state of the associated BindingSource.

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

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