运行效果：

使用代码生成器（GZCodeGenerate）生成tb_EmpLeave的Model

生成方式见上一节：

GZFramwork数据库层《一》普通表增删改查

新增一个自定义控件：ucTableUnitDocNo

后台代码同上一节ucTableUnit除了实例化bllBusiness不一样外其他都一样(红色背景标注)

using System;

using GZFramworkDB.BLL;

using GZFramworkDB.Main.MyControls;

namespace GZFramworkDB.Main

{

    public partial class ucTableUnitDocNo : UserControl,IData

    {

        bllBusiness bll;

        public ucTableUnitDocNo()

        {

            InitializeComponent();

            bll

= new bllBusiness(typeof(tb_EmpLeave), "AL",

);

        }

        public void DoSearch()

        {

            gridControl1.DataSource = bll.GetSummaryData();

            gridView1.BestFitColumns();//自动列宽

        }

        DataTable dtSource

        {

            get

            {

                if (gridControl1.DataSource == null) return null;

                return gridControl1.DataSource as DataTable;

            }

        }

        //新增

        public void DoAdd()

        {

            if (dtSource != null)

                dtSource.Rows.Add();

        }

        //主键删除，立即删除,无需提交

        public void DoDeleteKey()

        {

            DataRow dr = gridView1.GetFocusedDataRow();

            if (dr != null)

            {

                string Keyvalue = dr[bll.SummaryKey].ToString();

                if (bll.Delete(Keyvalue) == true)

                {

                    dtSource.Rows.Remove(dr);

                }

            }

        }

        //缓存表删除，需要提交生效

        public void DoDeleteTable()

        {

            gridView1.DeleteSelectedRows();

        }

        //提交

        public void DoUpdate()

        {

            bll.Update(dtSource);

        }

    }

}

修改Main.cs:

添加事件：

       //单据单表测试

        private void menu_TableUnitDocNo_Click(object sender, EventArgs e)

        {

            foreach (Control col in pan_MyControls.Controls)

            {

                col.Visible = false;

            }

            TableUnitDocNo.Visible = true;

            uc = TableUnitDocNo;

        }
