在GridView列中动态创建几个CheckBox

怎么嵌套，我的数据库中inputs字段是一个带空格的字符串

我想用gridview读出来，把info字符串变成可选的几个复选框，因为我还想选择这些复选框

分隔线上是某论坛一网友问及的问题。
要求也许是后期出现，刚开始时，只是让用户在文本框输入Info字段信息，后期才需要显示为CheckBox。因此最初设计是很重要，一稍没有想好，后面的开发，就是遇上很多问题。现在Insus.NET实现网友最初要求，把字符串改为CheckBox显示。既然改为CheckBox了，那肯定会有让用户选择，有先选择的功能，那也肯定需要存储选择的结果。因此Insus.NET分两步来做，首先是把字符串显示为CheckBox，第二步是保存选择结果。做好这个，得先准备好数据才行。

数据库层：

在ASP.NET层：
创建一个类别，Insus.NET.Information:

Information

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;

/// <summary>
/// Summary description for Information
/// </summary>
namespace Insus.NET
{
    public class Information
    {
        private string _Name;
        private string _Infor;

        public string Name
        {
            get { return _Name; }
            set { _Name = value; }
        }
        public string Infor
        {
            get { return _Infor; }
            set { _Infor = value; }
        }

        BusinessBase objBusinessBase = new BusinessBase();

        public Information()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        public DataTable GetAll()
        {
            return objBusinessBase.GetDataToDataSet("usp_Information_GetAll").Tables[0];
        }
    }
}

创建一个网页CheckBoxListGridViewDemo.aspx:

GridView控件，应该写上AutoGenerateColumns="false" ，因为应用了自定义列。另外使用 OnRowDataBound="GridView1_RowDataBound"事件，将用来动态为CheckBox绑定数据。

看看CheckBoxListGridViewDemo.aspx.cs:

看看效果：

第四行有问题，就是Info值为空时，它也有一个CheckBox，解决它，加个判断是否可行？

Ok,第一步完成，接下来是完成第二步，把用户选择的CheckBox存起来，还要重新显示于GridView上。
首先在数据库创建一个表，用于存储。还有两个存储过程：
