GridControl 二次封装，自定义颜色样式风格

1、自定义颜色格式，分组，筛选

1、封装类

 必须引用类库

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

2、调用类，如果在控件

 2.1 项目必须引用以下类库

2.2 工具箱中添加控件或者直接引用项目GridControlEx

2.3 调用代码

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 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()
        {

            SqlDataAdapter dap = new SqlDataAdapter(cmdtxt, cn);
            DataSet ds = new DataSet();
            dap.Fill(ds, "table");
            return ds.Tables[0];
        }

                 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[]{"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

       
    }
}
