There is a way, but you have to create a custom abstract class as the base class for your razor views. Then expose whatever you need to from parent to child actions. This is how I get the root controller's ViewBag inside a class inheriting from WebViewPage

    private dynamic GetPageViewBag()
    {
        if (Html == null || Html.ViewContext == null) //this means that the page is root or parial view
        {
            return ViewBag;
        }
        ControllerBase controller = Html.ViewContext.Controller;

        while (controller.ControllerContext.IsChildAction)  //traverse hierachy to get root controller
        {
            controller = controller.ControllerContext.ParentActionViewContext.Controller;
        }
        return controller.ViewBag;
    }
