Question

Hi
How can I use transaction with typed dataset? Let’s say I’ve a record table and record detail table and I’ve to save one in the record table and all the details in the record detail table.
How can I use ? I found transaction can be used with untyped dataset but I don’t see it with typed dataset. Can someone tell me how I should do?

There’s a nice article (and code) at CodeProject on how to extend the typed dataset to enable transactions without having them get promoted to a distributed transaction when using the TransactionScope.

Summary: Use the transaction scope with a method added on the partial class to modify the underlying SqlCommand objects to take part in the same transaction.

using (SqlTransaction transaction = connection.BeginTransaction())
{
       // These methods will update all relevant command objects’ transaction property
       adapter1.EnlistTransaction(transaction);
       adapter2.EnlistTransaction(transaction);

       adapter1.Update(table1);
       adapter2.Update(table2);

       transaction.Commit();
}

Code example for adapter from reference:

public partial class [TableAdapterName]
{
    public void EnlistTransaction(System.Data.SqlClient.SqlTransaction transaction)
    {
        System.Data.SqlClient.SqlTransaction _transaction;

        if (this._transaction != null)
        {
            throw new System.InvalidOperationException
        ("This adapter has already been enlisted in a transaction");
        }
        else
        {
            this._transaction = transaction;
            Adapter.UpdateCommand.Transaction = _transaction;
            Adapter.InsertCommand.Transaction = _transaction;
            Adapter.DeleteCommand.Transaction = _transaction;
        }
    }
}
