Changing the CardPageId in a Page Extension – Business Central Wave 1 2025

With the release of Business Central 2025 Wave 1, Business central continues to refine and empower AL developers with more flexibility when extending standard functionality. One of the subtle but significant features is the ability to change the CardPageId in a PageExtension, giving developers greater control over navigation behavior in the application.

Why Would You Want to Change CardPageID?

Consider these scenarios:

• Simplified Views: You’ve created a simplified version of a standard card page with only the most relevant fields for a specific user role. Now, you can easily link the standard list page to this streamlined card page for those users.
• Custom Workflows: Your custom solution requires a specialized card page with unique actions and fields for certain data. You can now seamlessly integrate this custom card page with the existing list of that data.
• Context-Specific Information: Depending on how a user navigates to a list page, you might want them to land on a different, more contextually relevant card page.

Let’s say you’ve built a custom card page for customers that shows additional analytics or fields. You want to replace the default Customer Card when users open a customer from the list.

page 50101 "Custom Customer Card"
{
    PageType = Card;
    SourceTable = Customer;
    ApplicationArea = All;

    layout
    {
        area(content)
        {
            group("Custom Info")
            {
                field("Customer Name"; Name)
                {
                    ApplicationArea = All;
                }
                // Additional fields and logic...
            }
        }
    }
}

Then, in your page extension:

pageextension 50100 CustomerListExt extends "Customer List"
{
    CardPageId = "Custom Customer Card";
}

Now, your users will be directed to the Custom Customer Card page instead of the standard one.

The ability to change the CardPageID in page extensions in Business Central Wave 1 2025 is a significant step forward in providing developers with more control over the user interface. This seemingly small change unlocks a wealth of possibilities for creating more tailored, efficient, and user-friendly Business Central solutions.

Stay tuned for more updates.
