Effortless Layout Editing in Business Central
Business Central Designer Mode enables drag-and-drop field editing through Visual Studio Code by pressing F6 instead of F5, automatically generating AL code from the visual changes made to pages without requiring manual coding.

"With F6 the system starts in Designer Mode."
Key points
- Pressing F6 in VS Code starts Business Central in Designer Mode; F5 starts the debugger
- In Designer Mode you can add fields with drag and drop, change field properties, show or hide actions and set importance
- Stop designing, save with Download Code checked, then press Alt+F6 in VS Code to pull the generated AL into the page extension
- Triggers and other advanced page logic cannot be handled in Designer Mode
- Lets developers adjust layouts together with end users and see the results right away
Quotes
