and controller:

    [httpget]     public actionresult index()     {         return view(new account_index_viewmodel());     }      [httppost]     [validateantiforgerytoken]     public actionresult login(useraccount_login_viewmodel model)     {         if (modelstate.isvalid)         {             if (dataprovider.loginuser(model, modelstate, request, session))             {                 return redirecttoaction("index", "home");             }         }         return view("index");     }      [httppost]     [validateantiforgerytoken]     public actionresult register(useraccount_register_viewmodel model)     {         if (modelstate.isvalid)         {             if (dataprovider.registeruser(model, modelstate, request, session))             {                 return redirecttoaction("index", "home");             }         }         return view("index");     } 

you should know server side validation works fine client side asleep. so, suggest?

when validation doesn't work mean? press login button empty username/password , doesn't show required error? if , created new project model view controller , worked !!! validation works.
