robh,
it's difficult to know from your question whether you're looking for a 'generic' or specific solution within your project. as such, i'm going to address the generic - works once, works everywhere solution.
this entails taking a few steps (convention over configuration). basically here's what's required:
- create new folder under
'views->shared called Editor Templates'
- create a new usercotrol (ascx) files
under that called 'string.ascx'
now, define that ascx file as per:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<string>" %>
<div class="editor-label">
<%= Html.LabelFor(model => model) %>
</div>
<div class="new-editor-field">
<%= Html.TextBoxFor(model => model) %>
<%= Html.ValidationMessageFor(model => model) %>
</div>
this will now make all 'string' based EditorFor() calls use this 'template'. simply make the class 'new-editor-field' reflect your desired css style for that field. obviously, cook as per your own requirement (i.e. you may not want the LabelFor tat etc..)
hope this helps - tho i have to say, this is just one of a few ways to do this (but is my prefered way).
enjoy
