Which UI property would you use to prevent editing a field while still displaying its value?

• A. Read-Only
• B. Required
• C. Hidden
• D. Control Width

Answer: (A)

The UI property you’d use is Read-Only. It keeps the field visible and showing its current value, but prevents the user from editing it. Why this fits: you often want to display data that should not be modified—perhaps calculated values or data sourced from elsewhere—without hiding it. Why the others don’t fit: Required enforces that a value must be provided, which is about input rather than display. Hidden would remove the field from view entirely, so the value wouldn’t be shown. Control Width only affects layout, not whether the field can be edited.
