Winform中GridView分組排序功效完成辦法。本站提示廣大學習愛好者：（Winform中GridView分組排序功效完成辦法）文章只能為提供參考，不一定能成為您想要的結果。以下是Winform中GridView分組排序功效完成辦法正文
本文實例講述了Winform中GridView分組排序功效完成辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：
1、成績：
因為客戶比來要擴大公司的營業，之前基於Winform+web開辟混雜式的體系曾經不克不及知足他們的需求，須要重新對體系停止分區處置。
斟酌到體系模塊外面用到的GridView視圖比擬多，我就聯合了DevExpress第三方GridControl簡略的寫了個Demo,對數據停止分組排序。
2、完成辦法：
主法式源碼：
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單擊事宜
/// </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>

private string MonthToString(int month)
{
if (month >= 1 && month <= 9)
return "0" + month.ToString();
