I'm trying to control access to certain pages via role-based authentication, and everything works fine except I'm having a hard time finding how to hide children of a page (in a partial view) if the member doesn't have access to those children.

For instance, I can type (strongly in this case):

@foreach(var item in Model.Content.Children.Where(item => item.IsVisible())

It will show pages that the user doesn't have authentication for. I'm looking to hide the page if the user doesn't have the authentication to see it, and I can't seem to find anything in examples or documentation (granted I haven't read through it all) that would work out of the box for a partial view page. Is there something like this or would I have to change my approach altogether?
