Syntax
<Result> = ListAdd(<Control to Use> [, <Element> [, <Path of Image to Display>]])
<Result>: Boolean
  • True if the element was added,
  • False otherwise.
WEBDEV - Browser codePHP ListAdd returns no result.
<Control to Use>: Control name
Name of control to use:
  • Memory list box,
  • Memory listview,
  • Memory combo box.
If this parameter corresponds to an empty string (""), the element is added into the List Box (or Combo box) control to which the current process belongs.
WEBDEV - Browser code The name of List Box (or Combo Box) control to use must necessarily be specified.
<Element>: Optional character string (with quotes)
Element that will be added into the specified control. If this parameter is not specified, an empty row is added into the List Box or Combo Box control.
This parameter can contain:
  • Carriage Return characters (CR) to add several elements.
  • tabulations (TAB) to get a multi-element list box (see the Notes).
  • gLink to indicate the value to return when selecting the element.
WINDEV For a Carousel control, the content of this parameter is displayed in the top left corner of Carousel control.
WINDEVWindows MobileJava For a ListView control, this parameter corresponds to the image caption. This parameter can contain Carriage Return characters (CR) to add several elements. In this case:
  • if <Path of Image to Display> is not specified, the added elements will be associated with the default image (defined in the "Details" tab of the description window of control).
  • if <Path of Image to Display> is specified, only the first element will be added. This element will be associated with the specified image.
WEBDEV - Server codeWEBDEV - Browser codeAndroidJavaPHP The Carriage Return characters (CR) are supported while the tabulations (TAB) are not supported.
WEBDEV - Server code To add several consecutive spaces, non-breakable space characters must be used: Charact(160).
<Path of Image to Display>: Optional character string (with quotes)
Name and path of image that will be added into a ListView control. You also have the ability to use an image memo item. This parameter is taken into account for the ListView controls displayed in ListView mode only. If this parameter is not specified, the default image (defined in the "Details" tab in the description window of control) will be used.
WEBDEV - Server codeWEBDEV - Browser codeAndroidiPhone/iPadUniversal Windows 10 AppPHP This parameter is not available.
Remarks

List boxes containing more than 10 000 elements

The maximum number of elements found in a List Box control is limited by the available memory (theoretical maximum: 2 billion rows). Nevertheless, filling a List Box control with an important number of elements (more than 10 000) affects the performances.
To add an important number of elements into a List Box control, we recommend that you use a browsing List Box control (which means a list directly linked to a HFSQL data file).
WINDEVWEBDEV - Server codeReports and QueriesAndroidiPhone/iPadWindows MobileJavaAjaxUser code (UMC)

Visibility/Invisibility of elements in a List Box or Combo Box control

To make an element invisible in a List Box or Combo Box control, use gLink.

Equivalence

The two following syntaxes are equivalent:
ListAdd(<List Name>, [<Element>])
and
<List Name>[Subscript] = <Element>
WINDEVWEBDEV - Server codeWEBDEV - Browser codeReports and QueriesAndroidiPhone/iPadWindows MobileUniversal Windows 10 AppJavaAjaxUser code (UMC)

Sorted/Unsorted List Box control

  • If the List Box control is sorted, the new element is inserted according to the sort order.
  • If the List Box control is not sorted, the new element is added at the end of the list.
The control type (sorted or not) is chosen during the control description ("Details" tab).

We recommend that you use ListAdd rather than ListInsert to add an element into a sorted List Box control.
WEBDEV - Browser code The element is added at the end of control, no matter whether the List Box control is sorted or not.
WINDEVReports and QueriesWindows MobileUser code (UMC)

Customizing the elements found in a List Box or Combo Box control

To customize the elements found in a List Box or Combo Box control (background color, image, drawing, ...), use the Functions for managing graphic strings.
WINDEVReports and QueriesWindows MobileUser code (UMC)

Tabulations: Multi-element List Box control

To manage the tabulations in a List box control (for aligning columns), use the TAB constant. For example:
ListAdd(LIST_Customer, LastName + TAB + FirstName)
In this example, all the first names start from the same position and are aligned one below another.
Note: The first call to ListAdd defines the position of tabulations. These positions will be taken as reference for all values added thereafter. Similarly, if values have been typed entered in the editor, the positions of these values are taken as reference. During the first call to ListAdd, we advise you to define the width of columns with Complete. For example, to fix the width of columns found in "CUSTOMERS" to 10 characters:
ListAdd(LIST_Customer, Complete(LastName, 10) + TAB + Complete(FirstName, 10))
WEBDEV - Browser code

Adding an element onto the browser

When adding an element in browser code, this element is added to the page displayed in the browser only. In order for this element to be added onto the server, ListAdd must be run on the server.
The call to ListAdd in browser code is convenient when using the AJAX technology, in "Programmed AJAX" mode (using AJAXExecute or AJAXExecuteAsynchronous).
Reminder: In "Automatic and immediate AJAX" mode, all you have to do is switch the server process containing ListAdd to automatic AJAX mode. That's it! No additional programming is required. See AJAX for more details.

Various

  • To add elements into a Table control, use TableAdd.
  • ListAdd can be used on:
    • a "Combo Box" column in a Table control.
    • a "Table" combo box.
