I have made certain elements Readonly conditionally by programming as depending upon the user. They become grayed out when made ReadOnly. Is there any command, may be Attribute ( ) command,  to make the grayed out Element (because of executed Readonly () command) make it clear and still remains readonly element?

There is a choice if you choose element to be ReadOnly in Control Panel to be "ReadOnly Not Grayed Out" but that would be ReadOnly for all users.

Thanks Ray. It works fine. Sorry for not checking the manual properly before posting. It is clearly mentioned in there.
