With the continuous evolution of the AL language in Microsoft Dynamics 365 Business Central, developers now have more flexibility when customizing user experiences. One such notable enhancement introduced in Business Central 2025 Release Wave 1 (v26) is the ability for Page Extensions to modify the CardPageID property of a List Page.
This small but powerful change can significantly improve how we tailor role centers, workspaces, and list-detail views for users—without needing to create full page copies.
Business Central 2025 release wave 1 (v26) and later., you can modify the CardPageID on list and listpart pages through a page extension. This means that you can override, which card page should be displayed when an end user double-clicks an item on the list page or listpart page.
Let’s watch a quick video how to replace the CardPageId property in Page Extension
Note:
If the property is already specified on the base page, the value in the page extension overrides it. If multiple page extensions modify the property, the last extension to be applied takes effect. Because per-tenant extensions are applied after AppSource apps, this implies that any race condition across multiple AppSource apps setting the same CardPageId can be resolved in a per-tenant extension if needed, although this will seldom happen.
