Question

I need to wrap the Validation Summary in a div. How do I set the Validation Summary to wrap it with a div when errors are present?

<div class="validation-summary"> 
  <%= Html.ValidationSummary("Login was unsuccessful. Please correct the errors and try again.") %>
</div>

Answer 1

I had to extend the validation summary extensions in another project of mine to deal with more than one form on a page.

Although this is different, you could create your own extension method…

namespace System.Web.Mvc
{
    public static class ViewExtensions
    {
        public static string MyValidationSummary(this HtmlHelper html, string validationMessage)
        {
            if (!html.ViewData.ModelState.IsValid)
            {
                return "<div class=\"validation-summary\">" + html.ValidationSummary(validationMessage) + "</div>"
            }

            return "";
        }
    }
}

Then just call

<%= Html.MyValidationSummary(
    "Login was unsuccessful. Please correct the errors and try again.") %>
