MVC 3: How to render a view without its layout page when loaded via ajax?

Question

I am learning about Progressive Enhancement and I have a question about AJAXifying views. In my MVC 3 project I have a layout page, a viewstart page, and two plain views.

Answer 1

Create two layout: 1. empty layout, 2 . main layout and then write in _viewStart file this code:

@{
if (Request.IsAjaxRequest())
{
    Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
}
else
{
    Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
}}

of course, maybe it is not best solution
