copied!<p>As @AaronShockley says, because <code>TextBoxFor()</code> returns an <code>MvcHtmlString</code>, your only option for developing a 'fluid API' style of amending the output would be to operate on the <code>MvcHtmlString</code>s returned by the helper methods. A slightly different way of doing this which I think approaches what you're after would be to use a 'property builder' object, like this:</p> <pre><code>public class MvcInputBuilder { public int Id { get; set; } public string Class { get; set; } } </code></pre> <p>...and to set up extension methods like this:</p> <pre><code>public static MvcHtmlString TextBoxFor<TModel, TProp>( this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProp>> expression, params Action<MvcInputBuilder>[] propertySetters) { MvcInputBuilder builder = new MvcInputBuilder(); foreach (var propertySetter in propertySetters) { propertySetter.Invoke(builder); } var properties = new RouteValueDictionary(builder) .Select(kvp => kvp) .Where(kvp => kvp.Value != null) .ToDictionary(kvp => kvp.Key, kvp => kvp.Value); return htmlHelper.TextBoxFor(expression, properties); } </code></pre> <p>You can then do stuff like this in your View:</p> <pre><code>@this.Html.TextBoxFor( model => model.Name, p => p.Id = 7, p => p.Class = "my-class") </code></pre> <p>This gives you strong typing and intellisense for input properties, which you could customise for each extension method by adding properties to an appropriate MvcInputBuilder subclass.</p>
