    public JsonResult GetAssData()
            {
                var x = (from n in db.Accessors
 join ctr in db.Countrys on n.CountryID equals ctr.CountryIDzjoin sts in db.States on n.StateID equals sts.StateID
   select new{ n.Id,n.Name,ctr.CountryID,ctr.CountryName,sts.StateName});
 return new JsonResult { Data = x, JsonRequestBehavior = JsonRequestBehavior.AllowGet };}

public JsonResult EditSer(int id = 0){
var x = (from n in db.Accessors where n.Id == id
  join ctr in db.Countrys on n.CountryID equals ctr.CountryID
  join sts in db.States on n.StateID equals sts.StateID
  select new{ n.Id, n.Name,ctr.CountryName,sts.StateName});
return new JsonResult { Data = x, JsonRequestBehavior = JsonRequestBehavior.AllowGet };}

public JsonResult BindCtry(){
  var x = from n in db.Countrys select n;
  return new JsonResult { Data = x, JsonRequestBehavior = JsonRequestBehavior.AllowGet };}

      public JsonResult BindStates(int Id=0)
            {
     var x = from n in db.States where n.CountryID ==Id select n;
 return new JsonResult { Data = x, JsonRequestBehavior = JsonRequestBehavior.AllowGet };}
