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:

复制代码 代码如下:
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();
        }
    }
}

DBHelp类源码:
复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace GridViewSortTest
{

        {
            return GetTable(strSQL, pas, CommandType.Text);
        }
        /// <summary>
        /// 执行查询,返回DataTable对象
        /// </summary>
        /// <param name="strSQL">sql语句</param>

        public static DataTable GetTable(string strSQL, SqlParameter[] pas, CommandType cmdtype)
        {

                SqlDataAdapter da = new SqlDataAdapter(strSQL, conn);
                da.SelectCommand.CommandType = cmdtype;
                if (pas != null)
                {
                    da.SelectCommand.Parameters.AddRange(pas);
