One way to do this would be to create an update page which will require you have three different record sets for each of the table, and then add three DA update server behaviors.
If you just want to view the tables, you can use tables and add use the DA Repeat Selection Server Behavior to loop over your tables.
You can also look at this url:
and look under the solution recipes, and click the Updating multiple records (Interactive Tutorial) tutorial.
Not sure if we understand one another. I created pages using DataAssist and SiteAssist for example events_update, events_delete, events_results, etc. When the admin logins in how do they navigate to each table or page to maintain their website? Need something similiar in nature to PowerCMS Admin Panel which I do own. Can you please tell me how to create the interface that the Admin will use to modify or maintain their website using the pages created in DataAssist. Thanks!
