I think you're trying to preempt some controller action (like Delete) with "enter code here":

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    string city = filterContext.ActionParameters["city"];
    string street = filterContext.ActionParameters["street"];

    // probably include this:
    //base.OnActionExecuting(filterContext);
}
