How do I make a field "read only" in Sitecore?

Question

In my "User" template, I have a "userid" field, which is a "Single Line Text" control. I want to make this field "Read Only" for all user items being created using this template. How can I do this?

Answer 1

Open the Security Editor, select the Role you want to give only read access. Make sure you have the Field read en Field Write volumns visible in the Security Editor (open the Columns-option in the header menu).

Then disable the Field Write for the selected field. Repeat this for every other Role you want to give only read access.

The check the access for the specific user/role in the Access Viewer.
