For details on the Refresh Action, refer to the description of the RefreshController.RefreshAction property that provides access to this Action.

If you need to inherit from the RefreshController, the following protected virtual methods are availabe for overriding:
|Method||When is it called?||Description|
|Refresh||Invoked as a result of executing the Refresh Action.||Represents the Refresh Action’s SimpleAction.Execute event handler. Refreshes object(s) from the current Object Space (see BaseObjectSpace.Refresh).|
|UpdateActionState||Invoked as a result of changes made to the current View’s Object Space:||Checks whether the Refresh Action’s active or enabled state should be changed, after the environment has been changed.|
