ValidationMessageFor with model and html attribute only - MVC 3

Question

Working on a MVC 3 application.

I need to add a class to the validation message html. I mean for span tag.

My Model

 [Required(ErrorMessage = "Role Name is required")]
 [RegularExpression(@"^[a-zA-Z ]+$", 
     ErrorMessage = "Only alphabets and spaces allowed")]
 public string RoleName { get; set; }

Markup

  <label for="name">RoleName</label>
  @Html.TextBoxFor(m => m.RoleName)
  @Html.ValidationMessageFor(m => m.RoleName, "some", 
                           new { @class = "immediate" })

But i could not see overloaded method like @Html.ValidationMessageFor(m => m.RoleName, htmlAttributes) . if i give some text, it is not showing my validaton message entered in model. It always shows that some text only.

Any fix for this?

You should be able to simply pass in null...

@Html.ValidationMessageFor(m => m.RoleName, null, new { @class = "immediate"})

i had a null missing, tx! – Holston

Neither null nor empty string for the second argument has the effect of failing over to the error message in the model - i seem to get an auto-generated message from the framework. Anything else prerequisite to getting this to work? – Afterbirth
