ASP.NET MVC partial views: input name prefixes

You can extend Html helper class by this :

using System.Web.Mvc.Html


 public static MvcHtmlString PartialFor<TModel, TProperty>(this HtmlHelper<TModel> helper, System.Linq.Expressions.Expression<Func<TModel, TProperty>> expression, string partialViewName)
    {
        string name = ExpressionHelper.GetExpressionText(expression);
        object model = ModelMetadata.FromLambdaExpression(expression, helper.ViewData).Model;
        var viewData = new ViewDataDictionary(helper.ViewData)
        {
            TemplateInfo = new System.Web.Mvc.TemplateInfo
            {
                HtmlFieldPrefix = name
            }
        };

        return helper.Partial(partialViewName, model, viewData);

    }

and simply use it in your views like this :

<%= Html.PartialFor(model => model.Child, "_AnotherViewModelControl") %>

and you will see everything is ok!
