Okay I'm very new to C# and i'm trying to create a little website using ASP MVC2.

I want to create my own authorization attribute. but i need to pass some values if this is possible.

For example:

    [CustomAuthorize(GroupID = Method Parameter?]
    public ActionResult DoSomething(int GroupID)
    {
        return View("");
    }

I want to authorize the access to a page. but it depends on the value passed to the controller. So the authorization depends on the groupID. Is this possible to achieve this in any way?.

Thanks in advance.
