- Control - item binding
- Control - variable binding
8. Binding controls to data
A window can display information from: - a database: controls are directly bound to the items in the data files or queries available in the database.
- variables in the application's WLanguage code (variables global to the window or to the project or parameters passed to the window).
To display information in a window, the controls in the window 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 window editor, in the control description ("Binding" tab).
- ScreenToFile updates the record or the variable with the values from the UI.
- FileToScreen updates the data in the UI with the values from the data file or variable.
