Assuming that I'm reading your post correctly, and you're not trying to access the controller/action names in the view, but INSTEAD trying to do something with them, and put the result into the viewdata:

You can't do it in the constructor because the context hasn't been created yet. You need to override the Initialize method:

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        base.Initialize(requestContext);

        //here the routedata is available
        ViewData["controller_name"] = (ControllerContext.RouteData.Values["Controller"];
    }

(Note that you could pass in just the ControllerContext.RouteData to your function and let it pick the values it needs.)
