Transaction issues

Can I use it this way，Will the transaction be sent to the server？

   using (var sc=new  System.Transactions.TransactionScope)
            {
                InOutStockBillEdit InOutStockBillEdit = DataPortal.Create<InOutStockBillEdit>();
                TransferBillEdit TransferBillEdit = DataPortal.Create<TransferBillEdit>();

                InOutStockBillEdit.BillDate = DateTime.Now;

                TransferBillEdit.BillDate = DateTime.Now;

                InOutStockBillEdit = InOutStockBillEdit.Save();
                TransferBillEdit = TransferBillEdit.Save();
            }

That will not work.

Code running in the logical client-side (like you show) is not running in the app server - logical or physical. So you can't start a transaction on the client and have it flow to the server - ADO.NET doesn't support that concept.

If you have multiple operations that need to run as part of a transaction, you should consider creating a unit of work class that encapsulates those steps, then you can invoke the unit of work as a single step.

There are examples of this in the Using CSLA 4 book. Normally these are a command object, but sometimes they are implemented using BusinessBase or ReadOnlyBase depending on exactly what needs to be done.

This is the sort of thing you need:

  [Serializable]
  public class BillDateUpdater : CommandBase<BillDateUpdater>
  {
    [Execute]
    [Transactional(TransactionalTypes.TransactionScope)]
    private void Execute()
    {
      InOutStockBillEdit InOutStockBillEdit = DataPortal.Create<InOutStockBillEdit>();
      TransferBillEdit TransferBillEdit = DataPortal.Create<TransferBillEdit>();

      InOutStockBillEdit.BillDate = DateTime.Now;

      TransferBillEdit.BillDate = DateTime.Now;

      InOutStockBillEdit = InOutStockBillEdit.Save();
      TransferBillEdit = TransferBillEdit.Save();
    }
  }
