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["PeriodEndDateModifiable"] 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

Answer 1

EditorFor works with metadata, so if you want to add html attributes you could always do it. Another option is to simply write a custom template and use TextBoxFor:

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

Answer 2

If you don't want to use Metadata you can use a [UIHint("PeriodType")] attribute to decorate the property or if its a complex type you don't have to decorate anything. EditorFor will then look for a PeriodType.aspx or ascx file in the EditorTemplates folder and use that instead.
