repeater中动态创建的checkboxlist或是radioboxlist取值，在线等。解决立即给分。

[M_arlboro]

在做一个调查统计系统。问题和答案分别为两张表，在调查的页面中有单选或是多选。根据问题表中的字段区分单选或是多选，并在后台中动态创建checkboxlist或是radiobuttonlist,以下为测试页面
HTML代码如下：

<asp:Repeater ID="rpQuestion" runat="server">
    <ItemTemplate>
        第<%# Container.ItemIndex + 1%>题：<%# Eval("Q_Name") %>：<br />
        选项：
        <asp:HiddenField ID="hfAnswer" runat="server" />
    </ItemTemplate>
</asp:Repeater>
<br />
<asp:Button ID="btnEnter" runat="server" Text="确定" OnClick="btnEnter_Click" />
<br />
结果：<asp:Label ID="lblInfo" runat="server"></asp:Label>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        string strSql = "select * from T_Question where Q_IsUsed=1";
        SqlDataAdapter sda = new SqlDataAdapter(strSql, DAL.DbUtils.GetConnection());
        DataSet ds = new DataSet();
        sda.Fill(ds);
        if (ds.Tables[0].Rows.Count > 0)
        {
            rpQuestion.DataSource = ds;
            rpQuestion.DataBind();
            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
            {
                bool IsType = Convert.ToBoolean(ds.Tables[0].Rows[i]["Q_Type"].ToString());//获取选项方式
                HiddenField hfAnswer = (HiddenField)rpQuestion.Items[i].FindControl("hfAnswer");
                if (IsType)
                {
                    CheckBoxList ckblist = new CheckBoxList();
                    ckblist.ID = "ckbAnswer" + i;

你应该用Repeater 嵌套Repeater
外层的Repeater显示题目，内层的显示选项
在内层的Repeater里面你把checkboxlist和radiobuttonlist都放上，设为隐藏

[M_arlboro]

[Quote=引用 9 楼 ojlovecd 的回复:]
试试把动态生成CheckBoxList和RadioButtonList的代码放到if(!IsPostBack)外面
[/Quote]
测试成功！能说说为什么会出现这样的情况吗？有点弄不明白。虽然这种方法不可取。因为点提交后又加载一次数据。

[houndsky]

顶起！

[M_arlboro]

呵呵。忘记加注释，因为是测试页面，代码也不规范。各位牛人别见怪

[liuyeede]

你现在的数据绑定正确无误？

[zhgroup]

我没用过这种方式处理，可以给你一个我的思路：
对于问题，你的数据库中一定有唯一编码，对于checkbox或radio类型的表单，可以在后台输出，
对于checkbox,可以以[“数据库唯一编码”_chk]这样的名称作为其唯一标识，radio也可采用此种方式，
然后在提交数据库，可以通过Request.Forms中，根据名称获取前台checkbox/radio的值

这有个例子.

[pgameli]

我以前做过问卷调查的项目
你应该用Repeater 嵌套Repeater
外层的Repeater显示题目，内层的显示选项
在内层的Repeater里面你把checkboxlist和radiobuttonlist都放上，设为隐藏

后台绑定数据的时候，外层Repeater绑定题目，内层绑定选项，内层绑定的时候就判断时候是单选还是多选或者是文本
然后把相应的控件设为可见，

就是这样一个思路
lz参考下

[Teng_s2000]

看着比较费劲!

[coodd]

9楼说得对。还有代码太凌乱，产生A_ds的过程应该放在数据访问层，比如DAL下面的类。

[javacaspnet]

如果是单个的取值用Text
如果是多个的List取值用SelectedValue

[xfreyes]

用datalist多好布局
