1. Creating the "RAD Pattern" project.
2. Creating the different pages of the pattern.
   • Form page.
   • Table page.
   • Relation page.
   • Vision plus buttons and pages.
   • Menus.
3. Generating the RAD pattern.
4. Using the RAD pattern.

The files to create

• A form for RADFileA.
• A form for RADFileB. A Vision Plus button (or a popup combo box) must allow you to select an element of RADFileA.
• A form for RADFileC. A Vision Plus button (or a popup combo box) must allow you to select an element of RADFileB.
• A table for RADFileA.
• A table for RADFileB.
• A table for RADFileC.
• A RADFileB/RADFileD relation page.

Standard to follow

Overview

• select an element of RADFileA from a form on RADFileB.
• select an element of RADFileB from a form on RADFileC.

• in the form page: a combo box and a button.
• a Vision Plus page. This page can be displayed by the button as a dialog box for example. This case is presented in this help page.

Creating the Vision Plus page

• a table.
• a Validate button (to validate the selection of the element) and a Cancel button.

1. Click among the quick access buttons.
   • The element creation window appears: click "Page" then "Page".
   • In the wizard that starts, select "Blank" and validate.
2. In the description window, enter the name of the page. This name must necessarily contain the name of the file displayed in the table (some examples: PAGE_Vision_RADFileA, PAGE_Visio_RADFileA, ...).
   Remark: If you want to indicate the name of the current file to the user, use the name of the file (RADFileA for example) in a caption. The RADFileX term will be automatically replaced by the caption of the file described in the analysis.
3. Save the page.
4. Create a Table control in the page: Under the "Creation" section, in the "Data" group, scroll down "Table" and select "Table".
5. In the wizard for table creation, specify the following characteristics:
   • Select "Display the data from a file or from a query".
   • Select the base file of the table (RADFileA for example).
   • Keep the proposed item as well as the search item.
   • Validate the name of the table.
6. Position the Table control in the page and define its size.
7. Create and position the different buttons of your page: Validate and Cancel.
8. Case of the Validate button.
   This button will be used to validate the selection in the table. The code of the Validate button is as follows:
   
   // Close the page with True in return value
   PageCloseDialog(True)
   
   
   Remark: the page is displayed as a dialog box (PageDisplayDialog). The True value can be returned to the calling page.
9. Case of Cancel button
   This button is used to cancel the selection.
   
   // Close the page with False in return value
   PageCloseDialog(False)
   
10. Initialization code of page
    
    // Position on the current record
    TableDisplay(TABLE_RADFileB, taCurrentFirst)
    
    // Default return value
    MyPage..ReturnedValue = False
    

Creating the necessary elements in the form page

• Form on RADFileB
• Form on RADFileC

1. Under the "Creation" section, in the "Usual controls" group, click on "Combo box" and then click in the page.
2. In the wizard for creating the combo box, select the following options:
   • "Display the data coming from a file or from a query".
   • Data file: RADFileA for a form on RADFileB, RADFileB for a form on RADFileC.
   • Keep the default options. The stored item must be the identifier of the file.
   • The combo box is linked to no item.
   • the name of the control is "COMBO_IDRADFileX" (COMBO_ is the prefix defined in the code style: it is not required if no programming charter is used). For example, for the RADFileB form, the combo box will be named COMBO_IDRADFileA.
3. Validate. The Combo Box control is created.

1. Under the "Creation" section, in the "Usual controls" group, click on and then click in the page.
2. In the description window of the control, specify the name of the button. This control has a name such as "BTN_VISION_RADFileX" (BTN_ is the prefix defined in the programming charter: it is not required if no programming charter is used). For example, for the RADFileB form, the button will be named BTN_VISION_RADFileA.
3. The click code of the button is as follows:
   
   // Open the vision page of RADFileB
   IF PageDisplayDialog(PAGE_Vision_RADFileB) = True THEN
   // Refreshes the content of the RADFileB combo box
   ListDisplay(COMBO_IDRADFileB)
   // Assign and position the combo box
   COMBO_IDRADFileB = RADFileB.IDRADFileB
   END
