    - tous les types de sources de données
    - tous les types de tampons (buffering)
    - saisie des données dans une grille

    Chaque fois que vous changez d'option de données, la grille est rechargée avec les nouvelles données.

    Pour simuler plusieurs utilisateurs simultanée, affichez ce formulaire dans plusieurs navigateurs simultanément (par ex. firefox et chrome) ; vous verrez comment les modifications de données par un utilisateur sont visibles par le ou les autre(s) utilisateur().

    L'
option 'R View' (vue distante) illustre le support du chargement progressif des données avec CursorGetProp("FetchAsNeeded") ; initialement la grille est chargée avec CursorGetProp("FetchSize") enregistrements ; chaque fois que vous déplacez le curseur vers la dernière ligne de la grille, un autre jeu de CursorGetProp("FetchSize") enregistrements se charge jusqu'à CursorGetProp("FetchIsComplete").
    Notez que, le curseur ne pouvant être modifié qu'
une fois tous les enregistrements chargés (CursorGetProp("FetchIsComplete")), la grille reste en lecture seule jusque là.

    This screen shows the various possibilities of updating data with FoxInCloud:
    - All types of data sources
    - All types of buffering methods
    - Updating data in a grid

    Every time you select another data option, the grid gets reloaded with new data.

    To simulate multiple simultaneous users, display this form simultaneously in multiple browsers (eg Firefox and Chrome); you will see how a user data changes are visible to other user(s).

    The 'R View' option (remote view) demonstrates progressive fetching using CursorGetProp("FetchAsNeeded"): initially CursorGetProp("FetchSize") records are loaded, whenever you move to the last visible row in the grid, another set of CursorGetProp("FetchSize") records loads in until CursorGetProp("FetchIsComplete").
    Please note that, as the cursor can be modified only when all records are fetched (CursorGetProp("FetchIsComplete")), grid remains read-only until then.
