MVC 3: Page Authorization based on Role

Hi All,

let say i have this Page and Role required to access it

Home: PublicRole
About: PublicRole
Invoice: PurchasingRole

i have navigation menu that populate based on user's Role that logon but it doesn't prevent if user type the URL manually..user still can access that Page eventhough user don't have permission to access it

using AuthorizationAttribute is something that i want to prevent because Admin have the ability to set the Menu based on Role

authorization article that i found is required user to Logon first before attempt to access the Page, it already done in my scenario

any insight?
thx,
erick

You can just check the user's roles as the first thing inside each Action method, and redirect if the user is not in the required roles.

C# Code:

// User object below comes from HttpContext.Current.User
if (!User.IsInRole("PurchasingRole")) {
    return RedirectToAction("Index");
}

thx tr333

that will be my last attempt because i will be coding the same code for each page and of course the role won't be hardcoded because the authorization is dynamic..

arrghhh...
