• a Scheduler control file field Scheduler control: the Scheduler control will be linked to a data file or a query. In this case, the data file contains the characteristics of the appointments.
• an Scheduler control on a variable: the Scheduler control will be linked to a variable (usually a class instance). In this case, the class lists the appointments with their characteristics.

Creating a Scheduler control based on a data file

• use the Scheduler control creation wizard. Simply select the option "Display data from an existing data file or query". Answer the questions in the wizard and validate.
• change the description of the Scheduler control.

1. Open the control description window (select "Description" in the context menu).
2. In the "Content" tab, select the "Data file/Query" option and choose the data source you wish to use. This data source can be:
   • a data file defined in the analysis,
   • a query of the project,
   • a query included in the window or page.
3. Bind the different items of the data source to the characteristics of the appointment. The elements preceded by a star are mandatory.
   Note If the associated data file does not directly contain the corresponding item, it is possible to create a multi-file binding.
4. Validate the description window of the Scheduler control. The Scheduler control is now based on a data file.

• change the description of the Scheduler control.

1. Open the control description window (select "Description" in the context menu).
2. In the "Content" tab, select the "Variable" option and select the data source used (class, etc.).
3. Bind the different elements (class members, for example) of the data source to the characteristics of the appointment. The elements preceded by a star are mandatory.
4. Validate the description window of the Scheduler control. The Scheduler control is now based on a variable.

Scheduler control file

• If the user handles the scheduler via the context menu (to add, delete or modify appointments, for example), the associated data file is automatically updated with the changes made in the control.
• If the user adds, deletes, or moves appointments with the mouse, the associated data file is automatically updated with the changes made in the control.
• If the user handles the appointments via a specific window or page, it is necessary to directly modify the data file linked to the Scheduler control. The displayed data will be automatically updated. It is also possible to use SchedulerDisplay to update the data displayed in the control.
