C# Code:


public override bool Update(DataSet data)
{
   _UserManualControlTrans = true; //手动启动事务
   
   try
   {
      this.BeginTransaction();//启动事务
      
      if (data.Tables[0].Rows[0].RowState == DataRowState.Added)
      {//新增记录
      _LastGeneratedKey = DocNoTool.GetDataSN(_CurrentTrans, "RG", true, 8);//生成流水号
      data.Tables[0].Rows[0][tb_ReturnGoodsRegister.DocNo] = _LastGeneratedKey;//设置流水号
   }
   
   base.Update(data);//提交数据
   this.CommitTransaction();//提交事务
   return true;
}
catch
{
   this.RollbackTransaction();//回滚
   return false;
}
}
