Winform中GridView分组排序功能实现方法

本文实例讲述了winform中gridview分组排序功能实现方法。分享给大家供大家参考。具体实现方法如下：

一、问题：

由于客户最近要扩充公司的业务，之前基于winform+web开发混合式的系统已经不能满足他们的需求，需要从新对系统进行分区处理。

考虑到系统模块里面用到的gridview视图比较多，我就结合了devexpress第三方gridcontrol简单的写了个demo,对数据进行分组排序。

二、实现方法：

主程序源码：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.windows.forms;
using devexpress.xtragrid.columns;
using devexpress.data;
namespace gridviewsorttest
{
    public partial class form1 : form
    {
        public form1()
        {
            initializecomponent();
        }
        private void form1_load(object sender, eventargs e)
        {
            initload();
            #region 分组排序代码
            gridcolumnsortinfo[] sortinfo = {
                new gridcolumnsortinfo(gdvsort.columns["get_year"], columnsortorder.ascending),
                new gridcolumnsortinfo(gdvsort.columns["id"], columnsortorder.descending),
                                 };
            gdvsort.sortinfo.clearandaddrange(sortinfo,1);
            #endregion
        }
        /// <summary>
        /// 初始化girdcontrol数据
        /// </summary>
        private void initload()
        {
           gdcsort.datasource= dbhelp.gettable(string.format(@"select id,name,get_year,
                        url_adrress  from  tb_sort_test"));
        }
        /// <summary>
        /// girdview单击事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void gdvsort_click(object sender, eventargs e)
        {
            if (gdvsort.focusedcolumn.fieldname.equals(@"name") && gdvsort.getfocusedrowcellvalue("name") != null)
            {
                string url = gdvsort.getfocusedrowcellvalue("url_adrress").tostring()+
                    gdvsort.getfocusedrowcellvalue("get_year").tostring() +
                    monthtostring(int.parse(gdvsort.getfocusedrowcellvalue("id").tostring())) +
                    gdvsort.getfocusedrowcellvalue("name").tostring()+".html";
                webbrowser.navigate(url);
            }
        }
        /// <summary>
        /// 月份转换成字符串
        /// </summary>
        /// <param name="month"></param>
        /// <returns></returns>
        private string monthtostring(int month)
        {
            if (month >= 1 && month <= 9)
                return "0" + month.tostring();
            else
                return month.tostring();
        }
    }
}
