The event handler receives an argument of type System.EventArgs containing data related to this event.
End-users can hide inplace editors by pressing the ENTER or ESC key or moving focus outside the edited cell. You can also perform the same in code by calling either the CloseEditor or HideEditor method. In any case, the HiddenEditor event is raised.
Note that the HiddenEditor event is raised after the edited value has been validated and the editor has been destroyed. You can handle this event to perform any cleanup necessary after ShownEditor event handler execution or to perform other actions at editor close.
