Make User Parameter read-only like Reference Parameter?

[DRoam]

I have some user parameters that are controlled by my add-in. I want make these read-only (like Reference Parameters are) so the user can't modify them, but I want to leave them as User Parameters. Is this possible?

I want to leave them as User Parameters because the read-only status might be turned on and off, and I don't want the parameter order to continually be shuffled around as parameters are changed back and forth between read-only and editable.

Hi,

Have you already tried to overwrite a Parameter.Expression at DocumentEvents.OnChange if the expression was changed?
