Html attributes for EditorFor() in ASP.NET MVC

Question

Why can't I pass in html attributes to EditorFor()? eg;

<%= Html.EditorFor(model => model.Control.PeriodType, 
    new { disabled = "disabled", readonly = "readonly" }) %>

I don't want to use metadata

Update: The solution was to call this from the view :

 <%=Html.EditorFor( model => model.Control.PeriodEndDate, new {Modifiable=model.Control.PeriodEndDateModifiable})%>

and use ViewData["Modifiable"] in my custom EditorTemplates/String.ascx where I have some view logic that determines whether to add readonly and/or disabled attributes to the input The anonymous object passed into EditorFor() is a parameter called additionalViewData and its properties are passed to the editor template in the ViewData collection.

Update MVC 5.1 now supports the below approach directly, so it works for built in editor too. http://www.asp.net/mvc/overview/releases/mvc51-release-notes#new-features (It's either a case of Great mind thinking alike or they read my answer :)

End Update

If your using your own editor template or with MVC 5.1 which now supports the below approach directly for built in editors.

@Html.EditorFor(modelItem => item.YourProperty, 
  new { htmlAttributes = new { @class="verificationStatusSelect", style = "Width:50px"  } })

then in your template (not required for simple types in MVC 5.1)

@Html.TextBoxFor(m => m, ViewData["htmlAttributes"])
