ASP.NET MVC 3 Razor html render partial, page, action, load page using ajax

@*controller is not working, path is required *@
@*RenderPage("~/Views/Home/Simple.cshtml") *@

@*controller is not working, path load from ~/Views/Shared/_LogOnPartial.cshtml *@
@*{ Html.RenderPartial("_LogOnPartial"); }*@

@*controller is working, path load from ~/Views/{controller}/{action}.cshtml *@
@*{ Html.RenderAction("Simple", "Home"); }*@
@*Html.Action("Simple", "Home")*@

Simple.cshtml is

if Layout == null then only write a html in simple.cshtml
else load layout.cshtml with simple.cshtml

Хар ухаанаар зөвхөн simple.cshtml доторхи html ийг ( магадгүй нэр хуудас дотор хэд хэдэн асtion ажиллуулах гэж байгаа бол ийм шаардлага гарна )
@{        Layout = null;       }
болгох хэрэгтэй. тэгэхгүй бол ( Layout = null; ийм код байхгүй л бол ) бүх хуудас дуудагдаж давхар давхар тагууд харагдана гэсэн үг.
Хэрэв AJAX аар тухайн хуудлыг дангаар нь дуудах гэж байгаа бол заавал Layout = null; гэх албагүй хоосон орхиход л болно

Жишээ нь: Ajax ашиглан List.cshtml г дуудах бол нэг иймэрхүү код байж болно
