DataAnnotation [Key] makes a field readonly, is there other?

Question

The Key DataAnnotation makes a field behave as ReadOnly when I use it in a DataForm or DataGrid since it denotes a DataBase key, but what if I just want to make it readonly because it's a calculated field?

Is there another DataAnnotation, other than Key, to make a field behave as ReadOnly in a DataForm?

Answer 1

Try the Editable annotation, with AllowEdit as false.

[System.ComponentModel.DataAnnotations.Editable(AllowEdit = false)]
