本文實例講述了Winform中GridView分組排序功能實現方法。分享給大家供大家參考。具體實現方法如下：

一、問題：

由于客戶最近要擴充公司的業務，之前基于Winform+web開發混合式的系統已經不能滿足他們的需求，需要從新對系統進行分區處理。

考慮到系統模塊里面用到的GridView視圖比較多，我就結合了DevExpress第三方GridControl簡單的寫了個Demo,對數據進行分組排序。

二、實現方法：

主程序源碼：

復制代碼代碼如下:

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 分組排序代碼
            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數據
        /// </summary>
        private void InitLoad()
        {
           gdcSort.DataSource= DBHelp.GetTable(string.Format(@"SELECT ID,NAME,GET_YEAR, 
                        URL_ADRRESS  FROM  TB_SORT_TEST"));
        }
        /// <summary>
        /// GirdView單擊事件
        /// </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>
        /// 月份轉換成字符串
        /// </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類源碼：

復制代碼代碼如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace GridViewSortTest
{
public class DBHelp
    {
        //連接字符串
      static string strConn =@"Server=./SQLEXPRESS; Database= SysBusiness; User Id=sa; Password=123456;Trusted_Connection = False ";

                }
