Is there a way to create an ActionLink with HTML 5 Data- attributes?

Question

HTML5 allows the use of custom attributes prefixed with the phrase \"data-\" which pass validation without the use of a custom DTD (more info). In Asp.Net MVC, is there any

Answer 1

or you can use

new { data_customattribute="value" }

and the compiler is smart enough to know what you mean

Answer 2

Yes, there is an overload for ActionLink method which takes an IDictionary<string,object> instead of an anonymous object.

<%=Html.ActionLink("text", "Index", "Home", null /*routeValues*/, 
    new Dictionary<string, object> { 
       { "data-customattribute", "value" }, 
       { "data-another", "another-value" } 
    })%>

Outputs :

<a data-another="another-value" data-customattribute="value" href="/">text</a>
