c# - Validation errors texts don't appear -

-



i have class 2 properties

[stringlength(8, errormessage = "user name can't longer 8 chars!")] [required(errormessage = "must filled!")] public string nickname { get; set; }  [required(errormessage = "must filled!")] [datatype(datatype.password)] public string password { get; set; }

and have partial view, user inserts details , presses sumbit button.

    nickname:     @html.textboxfor(x => x.nickname)     @html.validationmessagefor(x => x.nickname) </div>  <div>     password:     @html.textboxfor(x => x.password)     @html.validationmessagefor(x => x.password) </div>  <button type="submit">log in</button>

this post action,

[httppost] public actionresult login(shortuser u) {     if (modelstate.isvalid == true)     {         if (u.passmatchuser())         {             formsauthentication.setauthcookie(u.nickname, true);         }         else         {             modelstate.addmodelerror("error","username / password inncorect!");         }             return redirect(controllercontext.httpcontext.request.urlreferrer.tostring());         }         else         {             return redirect(controllercontext.httpcontext.request.urlreferrer.tostring());         }     }

if insert invalid values validation texts don't appear.

you need set validation summary on

@html.validationsummary(true)  @html.enableclientvalidation()

on partial view.
