devexpress grid 分页最后一页无法向前翻页 dev分页控件

 后记 --dev是有分页控件的,实现起来也是 多有设置. 没有layui 这些分页简单,可能是要用熟悉吧.以下的控件组合分页是多年前的刚入c# 时的demo  .只能算是一种练习的demo,甚至功能也不全面,现在建议用devexpress自带的 分页控件

sunnyui 也有分页但似乎有版权的版本才可以.

这个小小的功能实现起来还是有一点点复杂, 分页单独一个usercontrol 出来,导致查询换页 与gridcontrol页面分离,  一般通过换页事件通知girdcontrol 做出查询

查询来说有时是查询所有,有时是查询一个月,或者别的时间. 在分页控件内的控件上做相应的赋值.想想实现起来还是有一定的复杂度.

如果数据量足够大 : 第一步是先查出数据总量,根据总量,把分页上的 数量,页数.当前页等做初始化,把第一页的数据通过数据库查询先赋值给gridcontrol,其余页面等用户点击时进行赋值

查询数据总数:

/// <summary>
        /// 查询记录条数
        /// </summary>
        /// <returns>记录条数</returns>
        public int Count()
        {
            const string sql = "SELECT count(*) as id FROM [dbo].[Contacts]";
            using (SqlConnection connection = new SqlConnection(connstr))
            {
                int list = Convert.ToInt32(connection.ExecuteScalar(sql));
                return list;
            }

        }

数据库查询分页代码:

/// <summary>
        /// 分页
        /// </summary>
        /// <param name="pageIndex"></param>
        /// <param name="pageSize"></param>
        /// <returns></returns>
        public IEnumerable<Model.ScanAllData> Page(int pageIndex, int pageSize)
        {
            const string sql = @"select * from(select *,(ROW_NUMBER() over(order by id asc))as newId from Contacts) as t 
                                 where t.newId between (@pageIndex-1)*@pageSize+1 and  @pageSize*@pageIndex";
            using (SqlConnection connection = new SqlConnection(connstr))
            {
                var reader = connection.Query<Model.ScanAllData>(sql, new { pageIndex = pageIndex, pageSize = pageSize });
                return reader;
            }

        }

新建一个usercontrol , 加上panelcontorl  然后 从左到右 需 button , 输入框,下拉框 ,labelcontrol 挨个拖进

            catch (Exception)
            {

            }
        }
    }
}

调用:

加两个事件:

mgncPager1.myPagerEvents += MyPagerEvents; //new MgncPager.MyPagerEvents(MyPagerEvents);
            mgncPager1.exportEvents += ExportEvents;// new MgncPager.ExportEvents(ExportEvents);
public int curPage = 1;
        public int pageSize = 10;
        public int allcount = 0;
  public void ExportEvents(bool singlePage)//单页,所有      
        {
            //导出GridControl代码写在这。
        }
        public void RefreshGridList()
        {
            FillGridListCtrlQuery(curPage);//自己实现FillGridListCtrlQuery函数。      
        }

        private void FillGridListCtrlQuery(int curPage = 1)   //更新控件
        {
       //  GridControl1.DataSource = WebService.Pager(。。。。。//显示分页结果
        mgncPager1.RefreshPager(pageSize, allcount, curPage);//更新分页控件显示。
        }
        private void MyPagerEvents(int curPage, int pageSize)
        {
            this.curPage = curPage;
            this.pageSize = pageSize;
            FillGridListCtrlQuery(curPage);

        }

  mgncPager1.RefreshPager(pageSize, allcount, curPage);//更新分页控件显示。  

每次查询数据量大需要分页,需要初始化这个控件上的值.

不爱动弹自己整理就从这个地址下1分:

这个控件是个初步框架,里边添不同的需求,比如分类查询,还需要做相应修改.

后记 --dev是有分页控件的,实现起来也是 多有设置. 没有layui 这些分页简单,可能是要用熟悉吧.以上的控件是多年前的刚入c# 时的demo  .只能算是另一种实现方式,甚至功能也不全面,现在建议用devexpress自带的 分页控件
