c#根据后台数据，自动生成checkbox

前端在aspx中，添加生成checkbox的容器div：

<div id="container" runat="server"></div>

后台cs代码如下：

 1 private DbHelper m_oDbHelper = null;//dll,数据访问类
 2 protected void Page_Load(object sender, EventArgs e)
 3         {
 4             if (!IsPostBack)
 5             {
 6
 7                 int i = 0;
 8                 try
 9                 {
10                     if (this.m_oDbHelper == null)
11                     {
12                         this.m_oDbHelper = new DbHelper();
13                     }
14                     this.m_oDbHelper.OpenDbResource("");//打开数据库
15
16                     DbCommand oCmd = m_oDbHelper.CreateDbCommand();
17                     oCmd.CommandType = CommandType.Text;//指定sql类型是存储过程还是文本
18                     oCmd.CommandText = string.Format("select AreaId,AreaName from TB_PropArea  where AreaId = ParentAreaId order by AreaId,AreaName");//从数据库中选择出checkbox的id和checkbox显示的名称
19                     oCmd.Parameters.Clear();
20
21                     IDataReader reader = oCmd.ExecuteReader();
22
23                     while (reader.Read())
24                     {
25                         CheckBox cbk = new CheckBox();
26                         string sza = reader.GetValue(1).ToString();
27
28                         cbk.ID = reader.GetValue(0).ToString();
29                         cbk.Text = i + 1 + ". " + sza;
30                         this.container.Controls.Add(cbk);
31                         LogCentral.CurrentLogger.LogInfo("cbk" + (i + 1) + " " + cbk.ID + cbk.Text);//log文件，可以忽略
32
33                         i++;
34                     }
35
36                 }
37                 catch(Exception ex)
38                 {
39                     LogCentral.CurrentLogger.LogInfo(ex.ToString ());
40                 }
41                 finally
42                 {
43                     m_oDbHelper.CloseDbResource();
44                 }
45             }
46 }

生成后画面如下：

html显示如下：
