Link in validation summary message

Question

Is it possible to put a HTML link in validation summary message? For example I want to put a link to another page in case there is validation error:

@Html.Va         


        

Answer 1

The validation text is encoded before the ValidationSumary or ValidationFor, etc...

you just need tu decode the html, then create an MvcHtmlString ...

Exemple :

@HttpUtility.HtmlDecode(Html.ValidationSummary().ToString()).ToMvcHtmlString()

this is an extension i have made to make MvcHtmlString :

namespace System
{
    public static class StringExtension
    {
        public static System.Web.Mvc.MvcHtmlString ToMvcHtmlString(this string value)
        {
        return System.Web.Mvc.MvcHtmlString.Create(value);
        }
    }
 }

or you can create an HtmlHelper if you plan to reuse this:

namespace System.Web.Mvc.Html
{
    public static class FormHelper
    {
        public static MvcHtmlString ValidationSummaryEx(this HtmlHelper htmlHelper, bool excludePropertyErrors)
        {
            var original = htmlHelper.ValidationSummary(excludePropertyErrors);
            var decoded = HttpUtility.HtmlDecode(original.ToString());
            return decoded.ToMvcHtmlString();
        }
    }
}

Hope it help you or future viewer. Note: it work for all validations Summary and ValidationFor ...
