Hi John,

Are you talking about modifying the behavior of the OOB External List page that is rendering the contents from an External Content Type?

You may start with opening the list form page in SPD or VS and make some changes.  But what ultimately needed here is to create your own ASP.NET form page to replace the OOB External list form pages so you have full control over how the data will be rendered.

Should be a simple matter of changing one of the descriptors -- not sure which one. The bogus "answer" with all the convoluted non-helpful "have to do more work and recreate the world" stuff should not have been marked (by some outsider not even participating in the conversation) as anything. 

Had done this once - with a simple tag. Now I can't find it. When I do, I would be happy to share - a real, helpful answer.
