Answer 3

我是想问下怎么嵌套起来显示 ！ 单个的绑定这个我会！ 
就是用一个gridview绑定题目
题目下面用gridview来绑定答案选项！

Answer 4

用datalist嵌套
我这个有小例子<asp:DataList ID="DataList1" runat="server" OnItemDataBound="DataList1_ItemDataBound">
                        <ItemTemplate>
                            <td>
                                <tr>
                                    <td>
                                        <asp:Label ID="id" runat="server" Text='<%#Eval("questionid") %>' Visible="false"></asp:Label>
                                        <asp:Label ID="type" runat="server" Text='<%#Eval("questiontype" ) %>' Visible="false"></asp:Label>
                                        <%#Eval("questionname")%>
                                    </td>
                                </tr>
                                <tr>
                                    <td>
                                        <asp:DataList ID="dlanswer" runat="server" OnItemDataBound="dlanswer_ItemDataBound">
                                            <ItemTemplate>
                                                <td>
                                                    <asp:Label ID="aid" runat="server" Text='<%#Eval("answerid") %>' Visible="false"></asp:Label>
                                                    <asp:CheckBoxList ID="cb" runat="server" Visible="False" ValidationGroup="cb">
                                                    </asp:CheckBoxList>
                                                    <asp:RadioButtonList ID="rb" runat="server" Visible="False" DataTextField='<%#Eval("answername") %>'
                                                        DataValueField='<%#Eval("answerid") %>'>
                                                    </asp:RadioButtonList>
                                                    <asp:TextBox ID="txtContent" runat="server" Visible="False" TextMode="MultiLine"
                                                        Width="200" Height="80px"></asp:TextBox>
                                                </td>
                                            </ItemTemplate>
                                        </asp:DataList>
                                    </td>
                                </tr>
                            </td>
                        </ItemTemplate>
                    </asp:DataList>
后台这样判断 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (Request.QueryString["id"] != null)
            {
            MODULE_InvestQuestion miq = new MODULE_InvestQuestion();
            miq.InvestID = Convert.ToInt32(Request.QueryString["id"].ToString());
            try
            {
                DataList1.DataSource = bllquestion.SearchTable(miq);
                DataList1.DataBind();
            }
            catch (Exception ex)
            {
                js.JsMsg(ex.Message);
            }
            }
        }    }    //绑定外层datalist
    protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataList dl = (DataList)e.Item.FindControl("dlanswer");
            Label lb = (Label)e.Item.FindControl("id");
            try
            {
                MODULE_InvestAnswer mia = new MODULE_InvestAnswer();
                mia.QuestionID = Convert.ToInt32(lb.Text.Trim());
                DataTable dt = bllanswer.SearchTable(mia);
                ViewState["dt"] = dt;
                dl.DataSource = dt;
                dl.DataBind();
            }
            catch (Exception ex)
            {
                js.JsMsg(ex.Message);
            }
        }
    }
    //绑定内层datalist
    protected void dlanswer_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Label lbtype = (Label)e.Item.Parent.Parent.FindControl("type");
            string type = lbtype.Text.Trim();
            if (type.Equals("0"))//文本
            {
                TextBox tb = (TextBox)e.Item.FindControl("txtContent");
                tb.Visible = true;
            }
            if (type.Equals("1"))//单选
            {
                RadioButtonList rb = (RadioButtonList)e.Item.FindControl("rb");
                rb.DataSource = (DataTable)ViewState["dt"];
                rb.DataBind();
                rb.Visible = true;            }
            if (type.Equals("2"))//多选
            {
                CheckBoxList cb = (CheckBoxList)e.Item.FindControl("cb");
                cb.Visible = true;
            }
        }
    }
顺便说一下
 你结贴率够低的
