Data Annotation: Can't see error message in Required Attrib.
Oct 15 2017 10:49 PM
Hello!
I'm newbie in ASP.NET and i'm trying to use Data Annotations, but it's not working properly. The problem is when I try to submit a form without fill all Required fields I don't see the error message. The ModelState "if" in the controller seems to work fine because I only see the Content "Working properly!" if I fill both textbox.
I want to see the error message.
How do I do that?
The Model:
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
System.ComponentModel.DataAnnotations;
namespace
Test.Marcelo.Models
{
public
class
User
{
[Required(ErrorMessage =
"Name is mandatory."
)]
public
string Name { get; set; }
[Required(ErrorMessage =
"Last Name is mandatory."
)]
public
string LastName { get; set; }
}
}
Controller:
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
System.Web.Mvc;
using
System.ComponentModel.DataAnnotations;
using
Test.Marcelo.Models;
namespace
Test.Marcelo.Controllers
{
public
class
HomeController : Controller
{
// GET: Home
public
ActionResult Index()
{
return
View();
}
public
ActionResult UserForm()
{
return
View();
}
[HttpPost]
public
ActionResult Record(User usr)
{
if
(ModelState.IsValid)
{
return
Content(
"Working properly!"
);
}
return
RedirectToAction(
"Index"
);
}
}
}
The View:
@model Test.Marcelo.Models.User
@{
ViewBag.Title =
"UserForm"
;
}
<!DOCTYPE html>
<html>
<head>
</head>
<body>
@
using
(Html.BeginForm(
"Record"
,
"Home"
))
{
@Html.LabelFor(m => m.Name)
@Html.TextBoxFor(m => m.Name)
@Html.ValidationMessageFor(m => m.Name)<br />
@Html.LabelFor(m => m.LastName)
@Html.TextBoxFor(m => m.LastName)
@Html.ValidationMessageFor(m => m.LastName)<br />
<input type=
"submit"
value=
"Record"
/>
}
</body>
</html>
