Thanks Rip,
I can do this but I have a business object that is used in Web Forms, Windows Forms, Pocket PC's, Web Services. which means every time I need to populate I will have to do what you have reccomended. And also the staff who are designing the forms are mostly graphic designers, so we have to keep the UI very simple in terms of programming.
We have 2 properties for them to fill in the 1.Form's English Name and 2. The BO to be used for the form. So we use reflection a lot.

The Security - Contact is one to one which means when a new security row is added, Changed or deleted contact table is Added, Updated or deleted too, So I have all this code in pre & Post hooks.

Regards,
Fred

>You're probably only registering the Security bo in the form correct? Your will need to register both the Security object and the Contact object in the webform, which means you'll need to instantiate the Contact bo in the web form. Then, in the webform, set your Security.oContact property to that instantiated Contact object.
