Pages serve the purpose of input, output, and control. They are views of data or process information designed for onscreen display only. They are also user data entry vehicles.
Pages are made up of various combinations of Controls, Properties, Actions, Triggers, and C/AL Code, which are briefly explained here:
- Controls: These provide the users with ways to view, enter, and edit data, choose options or commands, initiate actions, and view status
- Properties: These are attributes or characteristics of an object that define its state, appearance, or value
- Actions: These are menu items that may be icons
- Triggers: These are predefined functions that are executed when certain actions or events occur
The internal structure of a page maps to a tree structure, some of which is readily visible in the Page Designer display while the rest is in the background.
