How to lock user using forms authentication

Question

Coding Platform: ASP.NET 4.0 Webforms with C#

I have two roles admin and member.
In my application, admin can manipulate most of the member data.
I know that in forms authentication a user can be unlocked like,

            MembershipUser user = Membership.GetUser(clickeduserName);
            user.UnlockUser();
            Membership.UpdateUser(user);

My questions are,

1. How to lock a user in forms authentication?
2. Why is MembershipUser.IsLockedOut Property set as ReadOnly?
3. Is it not the right way to LockOut people as an administrator?

There are a few options discussed here: http://forums.asp.net/t/1435151.aspx

They vary from using IsApproved (settable) instead of IsLockedOut to mucking with the underlying SQL database to set the lockout flag.
