Read-only on Text Field of the Tabular Form

1. Create a new Javascript function

Sample here is just to make one field (EName) read-only. Obviously more fields can be added if needed. To find out what number of wwv_flow.fxx is, please see Which Tabular Form Column is mapped to which Apex_Application.g_fxx array? by Patrick Wolf

The "silver" color is added to make it noticeable as read-only. More sample of attributes of document.wwv_flow.fxx can be found at Denes Kubieck's Demo under Code section.

2. Call this function from page's onload under the HTML Body Attribute.

No-Duplication Validation

Create a new page-level validation with PL/SQL and Function Returning Error Text.

Please see above link about g_fxx.
