Raises the BindingNavigator.RefreshItems event.
In addition to raising the corresponding BindingNavigator.RefreshItems event, the BindingNavigator.OnRefreshItems method performs the following operations against the state of the associated System.Windows.Forms.BindingSource.
Sets the internal members using the current System.Windows.Forms.BindingSource state.
Enables or disables user interface (UI) items appropriately for the current System.Windows.Forms.BindingSource state.
Updates the BindingNavigator.CountItem and BindingNavigator.PositionItem controls.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The BindingNavigator.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.
