This here should do the trick:

<%= Html.TextBox("MyTextbox", Model.MyValuenew,           
      (Model.IsMyTextboxEnabled() ? (object) new {id = "MyTextbox", @class = "MyClass"}
                                  : (object) new {id = "MyTextbox", @class = "MyClass", disabled="true" })) %>

In your helper would you have a check in 11 the code, when you are generating the html, that 10 simply checks the bool and then either adds 9 the disabled attribute or leaves it out?

This 8 is a simply example and not well structrued 7 but...

if (disabled)
return string.Format(CultureInfo.InvariantCulture, "<input type=text disabled/>", new object[] { HttpUtility.HtmlAttributeEncode(s), myTextBox });

Is this what you were asking?

EDIT:

Wait, I 6 see now. I think you'll need to either 5 create your own helper or extend the MVC 4 textbox helper so that you can do it.

Either 3 that or you can I think do something like;

<%= Html.TextBox("mytextbox","", new { disabled="true" } %>

The 2 above is untested but something like that 1 should work.

EDIT 2:

<% if (condition) {%>
  <%= Html.TextBox("mytextbox", "", new {@readonly="readonly"}) %>
<%} else {%>
  <%= Html.TextBox("mytextbox", "") %>
<%}

Too late maybe but hope it will help:

I´ve 12 been working with ASP MVC recently and (as 11 I refused to have one combination of Anonymous 10 types for each possible set of attributes) realized 9 that, as of MVC 2, every Input Extension 8 method has two forms: one with attributes 7 as Objects and one as IDictionary<string, Object> element. See the msdn API

So, I 6 ended up coding the following, which personally 5 I find far more convenient that creating 4 multiple objects (actually, for multiple 3 option or checkbox controls you can use 2 just one Dictionary and add or remove properties 1 at will):

 <% 
  IDictionary<string, Object> radioAttrs = new Dictionary<string, Object>();
  radioAttrs.Add("class", "radioBot");
  if (Model.EnabledRegistro)
  {
      radioAttrs["onclick"] = "updateControlsForInfoNom(true)";
  } 
  else
  {
     radioAttrs["disabled"] = "disabled";
  }
  %>

  <%: Html.RadioButtonFor(model => model.Accion.calculoRegistro, "true", radioAttrs)%>
  ...

With this method you can supply multiple 1 attributes if needed

@Html.TextBox("mytextbox", new {}, new { @class = "myclass", disabled = "true" })
