表单上实现增删改查，除了生成的BLL,DAL和ORM表，还需要处理什么？

namespace CSFramework3.DataDictionary
{
   /// <summary>
   /// 产品资料管理类
   /// </summary>
   public partial class frmProduct : frmBaseDataDictionary
   {
      private bllProduct _BllInstance; //业务逻辑层对象引用
      
      public frmProduct()
      {
         InitializeComponent();
      }
      
      private void frmProduct_Load(object sender, EventArgs e)
      {
         this.InitializeForm();
      }
      
      protected override void InitializeForm()
      {
         _SummaryView = new DevGridView(gvSummary);//每个业务窗体必需给这个变量赋值.
         _ActiveEditor = txtPcode;
         _KeyEditor = txtPcode;
         _DetailGroupControl = gcDetailEditor;
         _BLL = new bllProduct(); //业务逻辑实例
         _BllInstance = _BLL as bllProduct; //本窗体引用
         
         base.InitializeForm();
      }
      
      // 检查主表数据是否完整或合法
      protected override bool ValidatingData()
      {
         if (txtPcode.Text == string.Empty)
         {
            Msg.Warning("编号不能为空!");
            txtPcode.Focus();
            return false;
         }
         
         if (txtPname.Text.Trim() == string.Empty)
         {
            Msg.Warning("名称不能为空!");
            txtPname.Focus();
            return false;
         }
         
         
         if (_UpdateType == UpdateType.Add)
         {
            if (_BLL.CheckNoExists(txtPcode.Text))
            {
               Msg.Warning("编号已存在!");
               txtPcode.Focus();
               return false;
            }
         }
         return true;
      }
      
      /// <summary>
      /// 绑定输入框
      /// </summary>
      /// <param name="summary"></param>
      protected override void DoBindingSummaryEditor(DataTable summary)
      {
         try
         {
            if (summary == null) return;
            DataBinder.BindingTextEdit(txtPcode, summary, tb_Product.ProductCode);
            DataBinder.BindingTextEdit(txtPname, summary, tb_Product.ProductName);
            DataBinder.BindingTextEdit(txtPrice, summary, tb_Product.SellPrice);
            DataBinder.BindingTextEdit(txtRemark, summary, tb_Product.Remark);
            DataBinder.BindingTextEdit(txtSupplier, summary, tb_Product.Supplier);
         }
         catch (Exception ex)
         { Msg.ShowException(ex); }
      }
   }
}
