All I want to do is simply make something invisible...a navigation group on a DevExpress Navigation Bar Control.  Here is my attempt after setting up roles and permissions, then DDT to deploy:

if (SecurityBasics.CurrentUser.GetPermission("SystemMaintenance").Action == PermissionAction.Grant)
{
    AdminNavBarGroup.Visible = true;
}
else
{
    AdminNavBarGroup.Visible = false;
}

I have a role called "Administration".  A permission key was created for a category called Administration (not technically related).  The key is use above and it is called "SystemMaintenance".  The key is given grant rights for the "Administration" role.  I removed myself from that role to test.  The only thing that may be gumming up the works is the fact that my profile is marked as an administrator.  Does the administrator bypass any and all permission sets?

What would be nice is SecurityBasics.CurrentUser.IsInRole("Administration").  It would simply return a boolean value.  It look like I have to create a dictionary list then walk the list to see if the user is in the role or not.  Is that right?

Thanks for your help,
Bill
