1. Creating the "RAD Pattern" project.
2. Creating the different pages of the pattern.
   • Form page.
   • 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

• A table: This table is a table based on a data file, with file loaded in memory.
• Buttons used to perform the main actions: New, Modify, Delete, Back and Print if necessary.

Example: Table page on the RADFileA file of the Simple Template pattern:

Creating a Table page

1. Click in the quick access buttons.
   • The window for creating a new element is displayed: click "Page" then "Page".
   • The page creation wizard opens.
   • 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 table (some examples: PAGE_Table_RADFileA, PAGE_Tab_RADFileA, ...).
   Note: If you want to specify the name of the current file to the user, use the name of the file (RADFileA for instance) in a caption. The RADFileX term will be automatically replaced with the caption of the file described in the analysis.
3. Save the page.
4. Create a Table control on the page: under the "Creation" pane, in the "Data" group, pull down "Table and List Box" and select "Table".
5. In the table creation wizard, specify the following characteristics:
   • Select the "Display data from a file or query" option.
   • 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. The column corresponding to the identifier can be invisible if necessary.
7. Create and position the different buttons your page (validation, modification, deletion, print, back, ...). These buttons can have any name.
8. Case of addition button (New button for example).
   This button can be used to enter a new record in a form page for instance. The code of the New button can be:
   

   // Create a new record 
   HReset(RADFileA) 
   
   // Open the form of RADFileA in creation mode 
   PageDisplay(PAGE_Form_RADFileA)

9. Case of modification button (Modify button for example).
   This button can be used to modify a new record in a form page for example. The code of the Modify button can be:
   

   // Is a row selected? 
   IF TableSelect(TABLE_RADFileA) = -1 THEN RETURN 
   
   // Open the form of RADFileA in modification mode 
   PageDisplay(PAGE_Form_RADFileA)

10. Case of deletion button (Delete button for example).
    This button can be used to delete a selected record from the table for example.
    
    The code of the Delete button can be (for the table on RADFileA):
    

    // If the deletion is confirmed, delete the table row and
    // the corresponding record from the FileA file
    IF YesNo("Do you want to delete the record?") THEN 
    	// Delete the record from the table
    	TableDelete(TABLE_RADFileA) 
    	// Position on the current record
    	TableDisplay(TABLE_RADFileA, taCurrentFirst)
    END
    
    CASE ERROR:
    	Error("An error occurred during the deletion.", HErrorInfo())
    	RETURN

    
    In the code of the deletion 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)").
11. 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 correspond to the home page of the site and it can contain the main menu of the site. For more details, see Menu page.

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)
