In Your situation I weel be use Query Strings More info here

Your page object have life cycle between Begin Request and End Requests Begin Request -> Create PageObject -> do all events (function in page and control) -> Rendering Html -> destroy pageObject -> End Request

You may keep util information (objects) on ViewState (More info here) or Session (More info here) for passing it between pages

Did you know that Page has a property named "PreviousPage" ? :-)
