有看到一网友在论坛上问问题，Insus.NET尝试了一下，下面提供Insus.NET所理解的基础之上的解决方案，仅供参考，原问题如下：
在解决之前，先准备一些数据吧。端午节快到了，公司分福利，希望你们公司也有。数据集是一个Hashtable:
private Hashtable GetData() { Hashtable ht = new Hashtable(); ht.Add(1, "粽子"); ht.Add(2, "苹果"); ht.Add(3, "雪梨"); ht.Add(4, "荔技"); ht.Add(5, "现金"); return ht; }View Code
在站点上创建一个网页，在.aspx页面上，写上下面代码：
到Insus.NET的博客上，下载两个给件，是专为ListControl绑定的，已经重构过了的：

解压之后，把DLL拉入BIN目录中。如：
然后，我们去.aspx.cs为页面的CheckBoxList，DropDownList，RadioButtonList控件绑定数据源。
接下来，我们想在文本框填入一些值，这个值能够指向那些控件中选项的值，如果没有对应的值，控件将是回归至默认(缺省值)的状态。由于每个控件是不同的对象，为了能让它们能够互动，有一致的动作，Insus.NET写一个接口：
下面，要看你需要什么控件来互动了，也就是什么控件来接收文本框的值了。需要的控件，均接中写一个适配器(Adapter)，由于Insus.NET仅列举了三个，因此分别写三个适配器。
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusCheckBoxList/// </summary>namespace Insus.NET{ public class InsusCheckBoxList: InsusAdapter { CheckBoxList _CheckBoxList; public InsusCheckBoxList() { // // TODO: Add constructor logic here // } public void SetValue(WebControl wc, object value) { if (wc is CheckBoxList) { _CheckBoxList = (CheckBoxList)wc; foreach (ListItem li in this._CheckBoxList.Items) { li.Selected = li.Text == value.ToString() ? true : false; } } } }}InsusCheckBoxList
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusDropDownList/// </summary>namespace Insus.NET{ public class InsusDropDownList: InsusAdapter { DropDownList _DropDownList; public InsusDropDownList() { // // TODO: Add constructor logic here // } public void SetValue(WebControl wc, object value) { if (wc is DropDownList) { _DropDownList = (DropDownList)wc; this._DropDownList.ClearSelection(); foreach (ListItem li in this._DropDownList.Items) { if (li.Text == value.ToString ()) this._DropDownList.Items.FindByText(value.ToString()).Selected = true; } } } }}InsusDropDownList
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusRadioButtonList/// </summary>namespace Insus.NET{ public class InsusRadioButtonList: InsusAdapter { RadioButtonList _RadioButtonList; public InsusRadioButtonList() { // // TODO: Add constructor logic here // } public void SetValue(WebControl wc, object value) { if (wc is RadioButtonList) { _RadioButtonList = (RadioButtonList)wc; foreach (ListItem li in this._RadioButtonList.Items) { li.Selected = li.Text == value.ToString() ? true : false; } } } }}InsusRadioButtonList
如果还有基它，继续写出来......
下面就是Button按钮的Click事件：
好了，还是看看最终的效果吧：

早上来看到第一次所想的，有些地方，觉得设计不好。按照面向对象的设计理念来说，接口设计的藕合性过高，接口内方法SetValue需要带两个参数。理想的带一个参数为好。
因此，Insus.NET把接口改为：
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusAdapter/// </summary>namespace Insus.NET{ public interface InsusAdapter { void SetValue(object value); }}View Code
这样一改的话，那怎样知道是给那个一个控制赋值？ 解决这个问题，我们可以使用构造函数来处理。回到上面的那三个适配器InsusCheckBoxList，InsusDropDownList，InsusRadioButtonList，下面是重构好之后的适配器：
using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusCheckBoxList/// </summary>namespace Insus.NET{ public class InsusCheckBoxList : InsusAdapter { CheckBoxList _CheckBoxList; public InsusCheckBoxList(CheckBoxList checkBoxList) { this._CheckBoxList = checkBoxList; } public void SetValue(object value) { foreach (ListItem li in this._CheckBoxList.Items) { li.Selected = li.Text == value.ToString() ? true : false; } } }}InsusCheckBoxList
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusDropDownList/// </summary>namespace Insus.NET{ public class InsusDropDownList : InsusAdapter { DropDownList _DropDownList; public InsusDropDownList(DropDownList dropDownList) { this._DropDownList = dropDownList; } public void SetValue(object value) { this._DropDownList.ClearSelection(); foreach (ListItem li in this._DropDownList.Items) { if (li.Text == value.ToString()) this._DropDownList.Items.FindByText(value.ToString()).Selected = true; } } }}InsusDropDownList
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI.WebControls;/// <summary>/// Summary description for InsusRadioButtonList/// </summary>namespace Insus.NET{ public class InsusRadioButtonList : InsusAdapter { RadioButtonList _RadioButtonList; public InsusRadioButtonList(RadioButtonList radioButtonList) { this._RadioButtonList = radioButtonList; } public void SetValue(object value) { foreach (ListItem li in this._RadioButtonList.Items) { li.Selected = li.Text == value.ToString() ? true : false; } } }}InsusRadioButtonList
重构之后，控件就可以在适配器new实例化时，就传入去了。
可以参考下面重构全过程：

此部分内容，只是重构一下comments的语句，因为每个控件的适配器有实作接口，所以使用多态来重构它们。
