Deletion on the browser

When deleting elements from a List Box (or Combo Box) control in browser code, these elements are deleted on the page displayed in the browser only. In order for these elements to be deleted from the server, ListDeleteAll must be run on the server.
The call to ListDeleteAll in browser code is suitable when using the AJAX technology, in "Programmed AJAX" mode (via AJAXExecute or AJAXExecuteAsynchronous).
Reminder: In "Automatic and immediate AJAX" mode, all you have to do is switch the server process containing ListDeleteAll to automatic AJAX mode. That's it! No additional programming is required. See AJAX for more details.

Miscellaneous

  • To delete all the rows from a Table control, use TableDeleteAll.
  • ListDeleteAll can be used on a "Combo Box" table column.
  • For the editable Combo Box controls, the input area is cleared.
