对DataGrid的初步了解

由于以前对DataGrid的了解相当初浅，只能用来显示数据
今天做了一下对DataGrid的深入学习
通过在网上搜索相关资料，总算能让例子达到自己的初步要求
也开始明白为什么别人说学习是一个循序渐进的过程
主要用到的一些代码：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Xml;

    {

        private System.Windows.Forms.DataGrid dataGrid1;

        private System.Windows.Forms.RichTextBox richTextBox1;

        private System.Windows.Forms.DataGridTableStyle dataGridTableStyle1;
        private System.Windows.Forms.DataGridBoolColumn dataGridBoolColumn1;
        private System.Windows.Forms.Button button2;

        private bool flag =false;
        /**//// <summary>

        private System.ComponentModel.Container components = null;

        public Form1()
        {
            //
            // Windows 窗体设计器支持所必需的
            //
            InitializeComponent();

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }

        /**//// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        protected override void Dispose( bool disposing )
        {
            if( disposing )
            {
                if (components != null) 
                {
                    components.Dispose();
                }
