Apply class to @Html.ValidationMessageFor

Question

Model:

[Required(AllowEmptyStrings = false, ErrorMessage="Please enter student name.")]
[StringLength(20,ErrorMessage="Student name cannot be over 20 characters long")]
    public string StudentName { get; set; }

View:

@Html.ValidationMessageFor(m=>m.StudentName,new {@class = "validation"})

Seems like there is no such overload for ValidationMessageFor. How do I apply class to it?

Answer 1

I just looked this up.

So in your case try:

@Html.ValidationMessageFor(m=>m.StudentName,""/* or null or what you want the error message to be */, new { @class = "validation" })

Answer 2

By default it should be using .field-validation-error class.

All you have to do is customize that css.

.field-validation-error {
    color: red;
}

If you really want to change that class name to 'validation', then I do not know how.
