The GetPostBackEventReference method can be used with the Button control when the UseSubmitBehavior property is false. In this scenario, the GetPostBackEventReference method returns the client postback event for the Button control.
If registerForEventValidation is true, the GetPostBackEventReference(PostBackOptions, Boolean) method calls the RegisterForEventValidation(String, String) method to register the event reference for validation with a unique control ID that represents the client control that is generating the event.
