for

RedirectUrl = string.Format( "/BvIndex/Index/{0}/" + check + "?bvIndex-mode=select", iReturn ) 

you need an action method with three parameters (not exactly the following but something like this)

 public virtual ActionResult Index( int? id,bool? check, string bvIndex-mode ) {
}

Have you registered a route key that corresponds to check in your global.asax?
