- Control - item binding
- Control - variable binding
8. Binding controls to data
A page can display information from: - a database. In this case, controls are directly bound to the items in the files or queries available in the database.
- variables in the application's code (variables global to the page or to the project or parameters passed to the page).
To display this information in a page, the controls of the page must be bound to: - the different items in the database.
- the available WLanguage variables.
There are multiple methods to display and update values from a data source: - The binding between a control and an item or variable can be defined in the page editor, in the control description ("Binding" tab).
- PageToFile updates the record or variable with the data in the page.
- FileToPage updates the data displayed in the page with either the information saved in the data file or variable.
