在MVC3中，控制器如何知道不干扰验证的结果？

Question

I'm using C# , MVC3 and VS2010

I noticed that even though the valdiation results to false, the controller method still gets executed. This makes the validation useless on the server-side. Unless there is a way to get the result.

---- EDITS -----
Here is how i'm using it. Is it done properly? At least the validation messages show up, and the textbox turns red.

Model:

public class CategoriaModel
{
    [Required(ErrorMessage="Nome é obrigatório!")]
    [StringLength(10, ErrorMessage = "First Name max length is 10")]
    public string Nome { get; set; }



}

View:

@Html.ValidationSummary(true)
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js") %>" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js") %>" type="text/javascript"></script>
@using (Html.BeginForm("Salvar", "Test", FormMethod.Post))
{


    @Html.LabelFor(m => m.Nome)
    @Html.EditorFor(m => m.Nome)
    @Html.ValidationMessageFor(m=>m.Nome)                           


    <input type="submit" value="Salvar" />
}

Controller:

public ActionResult Salvar(CategoriaModel catModel)
        {

            ViewBag.StatusMessage = "Ok!";



            return View("Index");
        }

testing ModelState.IsValid property, however if client side validation fails the Action should not be called. Check if you're actually validating all your Model properties.
