Bonjour,

Lorsque l'on � besoin d'effectuer un grand nombre de traitement sur des listes (cr�ation, modification, suppression), il est tr�s fortement d�conseill� de le faire via une it�ration du type foreach.
L'API SharePoint met � notre disposition une m�thode :

Code :

S�lectionner tout - Visualiser dans une fen�tre � part

        // Summary*:
        //     Processes the specified batch string of commands for sending multiple requests
        //     to the server per transaction.
        //
        // Parameters*:
        //   strBatchData:
        //     A Collaborative Application Markup Language (CAML) string that contains the
        //     batch string of commands, which consists of a Batch element and any number
        //     of subordinate Method elements that each specify a Windows SharePoint Services
        //     remote procedure call (RPC) method.
        //
        // Return*:
        //     A string that contains the results.
        public string ProcessBatchData(string strBatchData);

Donc pour r�sum� cette m�thode attend en param�tre une commande batch �crite en CAML.

Voici les trois actions possibles :

1. Cr�ation
   

   Code :

   <Method ID="1">
           <SetList>[LIST GUID]</SetList>
           <SetVar Name="Cmd">Save</SetVar>
           <SetVar Name="ID">New</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
         </Method>

2. Modification

           <SetVar Name="Cmd">Save</SetVar>
           <SetVar Name="ID">3</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
         </Method>

3. Suppression
   

   Code :

   S�lectionner tout - Visualiser dans une fen�tre � part

   <Method ID="3">
           <SetList>71a9fac3-2e94-4246-8fec-41e30ea65b06</SetList>
           <SetVar Name="Cmd">Delete</SetVar>
           <SetVar Name="ID">4</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
           <SetVar Name="urn:schemas-microsoft-com:office:office#[Field Name]">[Value]</SetVar>
         </Method>

   Le tout doit �tre structur�e sous la forme :
