Search in the Action Bar (system only)

1. Check "Permitir búsqueda en el Action Bar". A new event is automatically associated with the Action Bar control: "Search validation".. This event makes search possible.
2. If the "Con historial de búsqueda" option is checked, the search history will be shown to the user.
   Note: The "Con botón para borrar el historial" option is used to automatically manage history blanking..

1. Create a search button in the Action Bar (a "Magnifier" button for example).
2. In the code of this option, use ActionBarSearchVisible to display the search edit control. For example:
   

   ActionBarSearchVisible(True, "Client à rechercher")

3. Open the WLanguage events associated with the Action Bar control. In the "Validating the search" event, enter the code used to perform the search and display the result. In this code, you have the ability to find out the value entered by the user via SearchValue.
   For example:
   

   // Recherche d'un produit. 
   // Le résultat est affiché dans un champ Zone répétée. 
   // La valeur recherchée correspond à un paramètre de la requête de base du champ Zone répétée. 
   REQ_Produits.ParamNom = ACTB_ActionBar.ValeurRecherche
   LooperDisplay(ZR_REQ_Produits, taReExecuteQuery)

• If the history of searches is enabled:
  • when the edit control is empty, the 10 last searches are proposed.
  • when the edit is started, 10 suggestions are displayed according to what was already typed.
• You have the ability to clear the history with ActionBarDeleteSearchHistory.
• If the "Con botón para borrar el historial" option is selected, an option to clear the history will appear at the end of the search results.
• Two WLanguage events are automatically added when search is enabled in the Action Bar:
  • Validating the search.
  • Modifying the search.
• Search cancellation: To find out whether the user has cancelled the search, test the value of the SearchValue property in the "Search validation" event.. This value is set to "" (empty string) in case of cancellation.
