您当前的位置: 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。
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(); } } }
