Customise Validation summary - asp.net-mvc-2

Question

I have used html.ValidationSummary to get all errors displayed on top of the page.
This will render list with errors on top of the page.
Example:
<ul>
<li>UserName is invalid</li>
</ul>
I have how ever need to render every item instead of list as custom div with additional html tags inside.
I need every line to be rendered as short example below (this is only one line):
<div>
<div class="right"><a href="#closeError">Close error</div>
<div class="right"><a href="#Update">Update Field</div>
<label>Error:</label> Name on the page is invalid.
</div>
What is your opininon how to achieve this rendering?
I have considered to create html helper where i will take ModelState and get all errors, but not sure this will work...

I have considered to create html helper where i will take ModelState and get all errors, but not sure this will work...
Why wouldn't that work?
public static class ValidationExtensions
{
public static IHtmlString MyValidationSummary(this HtmlHelper htmlHelper)
{
var formContext = htmlHelper.ViewContext.ClientValidationEnabled
? htmlHelper.ViewContext.FormContext
: null;
if (formContext == null && htmlHelper.ViewData.ModelState.IsValid)
{
return null;
}
var sb = new StringBuilder();
var htmlSummary = new TagBuilder("div");
var modelStates = htmlHelper.ViewData.ModelState.Values;
sb.AppendLine("<div class=\"right\"><a href=\"#closeError\">Close error</div>");
sb.AppendLine("<div class=\"right\"><a href=\"#Update\">Update Field</div>");
if (modelStates != null)
{
foreach (ModelState modelState in modelStates)
{
foreach (ModelError modelError in modelState.Errors)
{
var userErrorMessageOrDefault = GetUserErrorMessageOrDefault(modelError);
if (!string.IsNullOrEmpty(userErrorMessageOrDefault))
{
sb.AppendFormat("<label>Error:</label> {0}{1}", htmlHelper.Encode(userErrorMessageOrDefault), Environment.NewLine);
}
}
}
}
htmlSummary.InnerHtml = sb.ToString();
if (formContext != null)
{
formContext.ReplaceValidationSummary = true;
}
return MvcHtmlString.Create(htmlSummary.ToString(TagRenderMode.Normal));
}
private static string GetUserErrorMessageOrDefault(ModelError error)
{
if (!string.IsNullOrEmpty(error.ErrorMessage))
{
return error.ErrorMessage;
}
return null;
}
}
and then:
<%= Html.MyValidationSummary() %>
