Question

When I code my Razor HTML like this:

@using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl })) {
   @Html.ValidationSummary()
}

I get the following which is just what I want:

<div class="validation-summary-valid" data-valmsg-summary="true">
<ul>
<li style="display:none"></li>
</ul>
</div>

However what I need for the form is the following:

<form class="form" data-href="/User/Account/Register" id="registerForm">
   @Html.ValidationSummary()
</form>

With the above code I don’t get the validation-summary-valid class. Can
someone explain why this is or maybe suggest how I could code
HTML.BeginForm so that I can get the form definition that I need.

Use the overloaded BeginForm to include HtmlAttributes:

@using (Html.BeginForm("action", "controller", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form", @id = "registerForm", data_href = "/User/Account/Register" }))
{
    ....
}

The view engine won’t parse “data-href” so you have to use an underscore instead of a hyphen.
