In addition to raising the corresponding RefreshItems event, the OnRefreshItems method performs the following operations against the state of the associated BindingSource.
Sets the internal members using the current BindingSource state.
Enables or disables user interface (UI) items appropriately for the current BindingSource state.
Updates the CountItem and PositionItem controls.
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.
