Lightbox custom field to be read only

Hello to all,

I see how to add text fields, radios and so on to a Lightbox, but I cannot find a way to make one of these values, to be read only.
Let’s say Mark assigns to George a new task and then this is visible on the George’s calendar.

Then where George edits this event/task, I want to show a custom field “Assigned by”, where I’ll show something like: “Created by Mark, on 12 June 2014…”

Of ycourse this must be a read only string.

How can I acheive this?

Thank you,

you can try a template control for such cases


thank you.
Yes, using templates I can do what I need.

Thank ypu,
