Question

I want to assign HTML attributes to forms created with Html.BeginForm in ASP.NET MVC 3 views, but it seems I have to use the overload

BeginForm(this HtmlHelper htmlHelper, 
          string actionName, 
          string controllerName, 
          FormMethod method, 
          Object htmlAttributes
)

invoking it like this:

Html.BeginForm(null, null, FormMethod.Post, new {id = "my-form"})

Is there some easier way to do this, so I can pass e.g. new {id = "my-form"} as the only argument to Html.BeginForm?

No, there isn’t unless you write your own HTML helper:

public static class FormExtensions
{
    public static MvcForm MyBeginForm(this HtmlHelper htmlHelper, object htmlAttributes)
    {
        return htmlHelper.BeginForm(null, null, FormMethod.Post, htmlAttributes);
    }
}

and then:

@using (Html.MyBeginForm(new { id = "my-form" }))
{
    ...
}

Unfortunately you cannot use BeginForm as name because there is already an overload with the same signature in which the parameter represents routeValues though.
