Custom ValidationMessageFor Template

I'm using ASP.NET MVC 3 right now with unobtrusive jquery client validation.

By default, ValidationMessageFor generates a span tag with certain classes and attributes set. I would like it to generate a different template instead. For example, I might want a div tag with a certain background image.

Is this possible at all, or can I just obtain the plain text error message from there so I can do my own styling?

Thanks

In MVC 2, the span is hard coded. There is no way to use a div instead with ValidationMessageFor.

You can get the message similar to how the built-in helper does it:

if (modelError != null) {
    builder.SetInnerText(GetUserErrorMessageOrDefault(htmlHelper.ViewContext.HttpContext, modelError, modelState));
}

    private static string GetUserErrorMessageOrDefault(HttpContextBase httpContext, ModelError error, ModelState modelState) {
        if (!String.IsNullOrEmpty(error.ErrorMessage)) {
            return error.ErrorMessage;
        }
        if (modelState == null) {
            return null;
        }

        string attemptedValue = (modelState.Value != null) ? modelState.Value.AttemptedValue : null;
        return String.Format(CultureInfo.CurrentCulture, GetInvalidPropertyValueResource(httpContext), attemptedValue);
    }
