Displaying related tables in CAdminList?

Question

1C-Bitrix

In the admin panel, I display a table with invoices data (invoices table), in this table there is an act_id field leading to the ID of the acts table.
How can I display the title field from the acts table by act_id when displaying the invoices table in the act_id field?

Answer 1

When you add rows using the AddRow() method, just select the related data and that's it, in your case it's the title. See the order list file sale_order.php for an example.
