ASP.NET MVC, add single attribute

Question

For attribute="value" I use

@Html.TextBoxFor(x => x.Email, new { type = "email", @class = "form-control",
 placeholder="Email address" })

it gives me:

<input class="form-control" id="Email" name="Email" placeholder="Email address"
 type="email" value="" />

How can I add single attribute to that, so I need required and autofocus:

<input class="form-control" id="Email" name="Email" placeholder="Email address" 
type="email" value=""  required autofocus />

Thanks!

What's wrong with using new { required = "required" }? As far as I know that would be the only way to do it. That won't give you exactly the markup you want but it'll still work. — dom

If you use string.Empty you will get an empty attribute in the generated html

@Html.TextBoxFor(x => x.Email, new { type = "email", @class = "form-control",
placeholder = "Email address", required = string.Empty, autofocus = string.Empty })

It generates me: autofocus="" and required="", but I need just autofocus required

@ihorko that's interesting... For me, I get just "required autofocus"

autofocus="" is still valid. stackoverflow.com/questions/2998247/…
