my shoppinglistscontroller:

[httppost]         [validateantiforgerytoken]         public actionresult create(partialviewmodel d)         {             // add "current group" each new item , put in database             d.youritem.groupid = convert.toint32(request.cookies["selectboxvalue"].value);             db.shoppinglists.add(d.youritem);             db.savechanges();              pv.mylist = db.shoppinglists.tolist();              return partialview("_liste");         }
