I have a layout page and some pages that use it. But I want to implement a navigation control on some of the sub-pages that use it. So I want to use another nested layout page.
Yes, it works great. Just tell your layout page to use another layout page
@{ Layout = "pathToMyOtherLayout"; }
You can also use sections to pass through to the parent layouts. For example:
@Section Headers {@RenderSection("Headers")}
