Answer 1

 string str = string.Empty;
            str += "<div onmouseover=\"show_click(1);\" id=\"lbtab1\" class=\"dalei\"><a href=\"#\">大类别名称</a></div>";
            Response.Write(str);看看输出什么？其他的就按照这样输出

Answer 2

你这种写法不好，就呢的这个需求，大类别下有各种小类别的话，使用Repeater嵌套就可以实现了，而且还很方便。
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
   <HeaderTemplate>
        <table>
  </HeaderTemplate>  
   <ItemTemplate>
             <tr>
                    <td><%#Eval("大类别")%></td>
                    <td>
                           <asp:Repeater ID="Repeater2" runat="server">
                                         <HeaderTemplate>
                                              <table>
                                         </HeaderTemplate>  
                                         <ItemTemplate>
                                                  <tr>
                                                              <td><%#Eval("小类别")%></td>
                                                 </tr>
                                         </ItemTemplate>
                                          <FooterTemplate>
                                                </table>
                                          </FooterTemplate>
                          </asp:Repeater>
                    </td>
             <tr>
    </ItemTemplate>
    <FooterTemplate>
         </table>
    </FooterTemplate>
</asp:Repeater>public void Page_Load(object sender,EventArgs e)
{
           if(!IsPostBack)
           {
                    //绑定你的第一个Repeater
                     ...
                  Repeater1.DataSource = ds;
                  Repeater1.DataBind();
           }
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater rpt = (Repeater)e.Item.FindControl("Repeater2");
            ...
            rpt.DataSource = ds;
            rpt.DataBind();
        }
    }

Answer 3

你可以用后台拼接输出，或者repeater嵌套repeater

Answer 4

后台直接输出HTML可以。循环这一段<div onmouseover="show_click(1);" id="lbtab1" class="dalei"><a href="#">大类别名称</a></div>
<div id="xxlb1" class="xialei" style="display:none;">
<ul>
  <li><a href="#">小类别</a></li>
  <li><a href="#">小类别</a></li>
</ul>
</div>

Answer 5

你是说不会处理那些123么？给结果集添加一个index列就行了，那些123的就绑定index列
