Getting the strongly typed HTML helper value into a simple parameter type

I have an ActionMethod and I'm trying to bind a string from a value supplied by a strongly typed HTML helper:

public class SampleController : Controller
{        
    public ActionResult Save(string name)
    {
        return Content(name);
    }
}

My view contains complex objects... and I'm trying to use strongly typed helpers as such:

@model MvcApplication2.Models.Sample

@using(Html.BeginForm("save", "sample")) {
   @Html.TextBoxFor(x =>x.Product.Name)
   <input type="submit" />
}

I know that the TextBox renders with the name Product.Name

<input id="Product_Name" name="Product.Name" type="text" value="">

and that I can bind to a complex Product type with the name product:

public ActionResult Save(Product product)
{
    return Content(product.Name);
}

or use the Bind attribute to bind to a property with a different name: 

public ActionResult Save([Bind(Prefix="Product")]Product p)
{
   return Content(p.Name);
}

but how do I get it to bind to just a string value?

public ActionResult Save(string name)
{
    return Content(name);
}

Thanks, Brian

Use the full prefix (the value of the name attribute) of the input field. For example:

public ActionResult Save([Bind(Prefix="Product.Name")]string name)
{
   return Content(name);
}

If you desire even more control you can always use a custom model binder:

public class CustomModelBinder : IModelBinder
{
    // insert implementation
}

public ActionResult Save([ModelBinder(typeof(CustomProductModelBinder))]string name){
    // ...
}
