1. Creating the "RAD Pattern" project.
2. Creating the different pages of the pattern.
   • Form pages.
   • Table page.
   • Relation page.
   • Buttons and Vision Plus page.
   • 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

• A supercontrol: This supercontrol contains the controls of the form to display. This supercontrol is linked to the file to display.
• Buttons used to Validate or Cancel (back button).
• Vision Plus buttons used to select elements of another file in a specific page (for the forms regarding RADFileB and RADFileC only).

Example of Form page for the Intranet pattern:

To create a form page:

1. Click among the quick access buttons.
   • The element creation window appears: click "Page" then "Page".
   • The page creation wizard starts.
   • Select "Blank". You can select the template used in your pattern.
2. In the description window, enter the name of the page. This name must necessarily contain the name of the file displayed in the form (some examples: PAGE_Form_RADFileA, PAGE_For_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 supercontrol in the page: on the "Creation" pane, in the "Containers" group, click "Supercontrol". This supercontrol will display the controls found in the form. Position this control in the page and define its size. Scrollbars will be automatically displayed if some of the controls cannot fit in the specified size.
5. In the supercontrol description window, specify the name of the supercontrol. This name must necessarily be SC_Form (SC_ is the prefix defined in the code style: it is not required if no code style is used).
6. In the "Content" tab of the supercontrol description window, specify:
   • the file browsed: RADFileXX ("RADFileA" for example).
   • the item browsed: IDRADFileXX ("IDRADFileA" for example).
7. Create and position the different buttons of your page: validation button, back button. These buttons can have any name.
8. Case of validation button ("OK" or "Validate" button for example).
   In the code of the validation button, we advise you to enable the automatic management of errors ("If Error: ", with the automatic process "Run the error process ("CASE ERROR:" in the code)").
   The code of the validation button can be (for a form on RADFileA):
   
   // Read the information entered
   PageToFile()
   // If it's a new record
   IF RADFileA..NewRecord = True THEN
   // Add it
   HAdd(RADFileA)
   ELSE
   // Modify it
   HModify(RADFileA)
   END
   // Back to the previous page
   IF PreviousPage() = "" THEN
   PageDisplay(PreviousPage)
   ELSE
   PageDisplay(PAGE_Home)
   END
   
   CASE ERROR:
   Error("An error occurred during the validation.", HErrorInfo())
   RETURN
   
9. Case of return button ("Back" button for example).
   
   // Are we coming from a page?
   IF PreviousPage() = "" THEN
   // Yes, display this page
   PageDisplay(PreviousPage())
   ELSE
   // No, go back to the home page
   PageDisplay(PAGE_Home)
   END
   
   
   Remark: This code requires the presence of a page named "PAGE_Home" in the RAD pattern. This page can be the home page of the site and it can contain the main menu of the site. See Menu page for more details.
10. Enter the initialization code of the page. Example:
    
    // Display the records
    FileToPage()
    
    
    This code is used to display the value of the records in the form.
11. Add the Vision Plus buttons if necessary (for the RADFileB and RADFileC forms).

Case of print buttons

• The name of these reports must contain RADFileX. For better readability, we recommend that you use "Form" or "Table" in the name of the form to easily identify the type of the report.
• This name must be used in the code of the print button:
  
  // Create a unique file name
  sFile is string = fDataDir() + "\" + DateSys() + TimeSys() + ".pdf"
  // Print the report in a PDF file
  iDestination(iPDF, sFile)
  // Generate the report
  iPrintReport(RPT_List_RADFileA)
  // Display the report in PDF format
  FileDisplay(sFile, "application/pdf")
  // Delete the file
  fDelete(sFile)
