感觉你这个应该是多选吧，
为什么不用CheckboxList控件呢
页面： 添加了CheckBoxList 控件和一个Button控件
<asp:CheckBoxList ID="CheckBoxList1" runat="server"
RepeatDirection="Horizontal">
<asp:ListItem>飞机</asp:ListItem>
<asp:ListItem>坦克</asp:ListItem>
<asp:ListItem>大巴</asp:ListItem>
</asp:CheckBoxList>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
代码： 在Button的Click事件中遍历的CheckBoxList的Itme
protected void Button1_Click(object sender, EventArgs e)
{
ArrayList al = new ArrayList();
for (int i = 0; i < this.CheckBoxList1.Items.Count; i++)
{
if (this.CheckBoxList1.Items[i].Selected)
{
al.Add(this.CheckBoxList1.Items[i].Value);
}
}
}

checkbox.text

服务器控件就用foreach
HTML控件就用request.form

foreach (string s in Request.Form.AllKeys)
{
controlId = "cb" + strRID;
if (s.Substring(s.Length - controlId.Length, controlId.Length) == controlId)
{
if (Request.Form[s] == "on")
{
//dv[i]["State"] = 1;
state = true;
}
}
}

.aspx
<input type='checkbox' name='cbType' value='typeValue' />text
。。。
.cs
string cb=Request.Form['cbType'];//cb的值为“1，2，3”选择多个值将以逗号隔开

循环取.selected=true的值不就行了?

前台循环绑定HTML控件
<script language="javascript" type="text/javascript">
function aaa()
{
var s="";
var v="";
var n="";
var index1="cbk_";
s=document.getElementsByName("qq");
for(var x=0;x<s.length;x++)
{
if(s[x].checked==true)
{
v=v+s[x].value+",";
}
else
{
n=n+s[x].value+",";
}
}
document.getElementById("hdf_id").value=v;
document.getElementById("hdf_nid").value=n;
// document.write(w);
// document.write(d);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td></td>
<td></td>
</tr>
</table>
<table>
<tr>
<td>Username</td>
<%
DBaccess DBA = new DBaccess();
int counti = DBA.countitems();
DV2 = DBA.selectitems();
DV3 = DBA.selectusers();
for (int i = 0; i < counti; i++)
{
%>
<td><%=HttpUtility.HtmlAttributeEncode(DV2[i]["itemname"].ToString())%></td>
<%
}
%>
</tr>
<%
int countu = DBA.countuser();
for (int i = 0; i < countu; i++)
{
%>
<tr>
<%
for (int j = 0; j < counti + 1; j++)
{
%>
<%
if (j == 0)
{
%>
<td><label><%=HttpUtility.HtmlAttributeEncode(DV3[i]["username"].ToString())%></label></td>
<%
}
%>
