1、自定义颜色格式，分组，筛选
1、封装类

2、调用类
项目必须引用以下类库
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 Bestway.Windows.Tools;
using System.Data.SqlClient;
namespace gridView
{
public partial class Form1 : Form
{
//public GridViewDev gridViewDev=new GridViewDev();
public Form1()
{
InitializeComponent();
gridControlEx1.InitView();
}
private void Form1_Load(object sender, EventArgs e)
{ //汉化，此处注意要使用汉化项目属性必须是.net fremawork4，不能是.net fremawork profile
DevExpress.XtraEditors.Controls.Localizer.Active = new DevExpress.LocalizationCHS.DevExpressXtraEditorsLocalizationCHS();
DevExpress.XtraGrid.Localization.GridLocalizer.Active = new DevExpress.LocalizationCHS.DevExpressXtraGridLocalizationCHS();
#region LoadData
DataTable tb = createTable(3,3);
//DataTable tb =SQLcreate();
gridControlEx1.DataSource = tb;
#endregion
gridControlEx1.InitGroup(0);
}
public DataTable SQLcreate()
{
string cmdtxt = "SELECT * FROM v_Personnel";
SqlConnection cn = new SqlConnection("server=.;database=mydb;Uid=sa;Pwd=123");
SqlDataAdapter dap = new SqlDataAdapter(cmdtxt, cn);
DataSet ds = new DataSet();
dap.Fill(ds, "table");
return ds.Tables[0];
}
#region createTable
private DataTable createTable(int colCount, int rowCount)
{
DataTable table = new DataTable();
table.TableName = "示例表";
for (int i = 0; i < colCount; i++)
{
DataColumn col = new DataColumn();
col.Caption = "列" + i.ToString();
col.ColumnName = "列" + i.ToString();
table.Columns.Add(col);
}
List<string[]> lst = new List<string[]>() {
new string[]{"1", "1", "1" },
new string[]{"2", "2", "2" },
new string[]{"2", "2", "2" },
new string[]{"2", "2", "2" },
new string[]{"3", "3", "3" }};
foreach (var item in lst)
{
//DataRow row = table.NewRow();
table.Rows.Add(item);
}
/*
for (int j = 0; j < rowCount; j++)
{
DataRow row = table.NewRow();
for (int i = 0; i < colCount; i++)
{
row[i] = "行" + j.ToString();
//row[i] = "行" + j.ToString() + "，列" + i.ToString();
}
table.Rows.Add(row);
}
*/
return table;
}
#endregion
}
}
