上面是我换了一个名称的也不对

Answer 5

我前面已经有个<asp:DataList ID="dlbbs" runat="server"> CS文件里竟然提示当前上下文中不存在dlbbs

Answer 6

重新做！
看着都没劲哦
后台用控件前面加this.控件ID

Answer 7

repeater是在datalist里面么？如果是
你都用了嵌套了！~。。肯定会提示了
嵌套是很麻烦，性能很低的做法最好不要用嵌套。。

Answer 8

<asp:DataList ID="dlbbs" runat="server">
  <ItemTemplate>你把 <ItemTemplate>里面的东西删除了 再运行看是否能行 
把<asp:Label ID="Label1" runat="server">删掉 直接放小脚本 运行

Answer 9

就是这样
<asp:DataList ID="dlbbs" runat="server">
  <ItemTemplate>
  <table style="width: 956px">
  <tr>
  <td rowspan="2" style="right: 50px; background-color:Red">
    
  </td>
  <td>
  <%#DataBinder.Eval(Container.DataItem,"ModuleNumel" )%>
  </td>
  <td rowspan="2" style="background-color:Red">
  B
  </td>
  </tr>
  <tr>
  <td>
  </td>
  <td>
  <%#DataBinder.Eval(Container.DataItem,"ModuleName" )%>
  </td>
  <td>
  </td>
  </tr>
  </table>
  </ItemTemplate>
  </asp:DataList>

Answer 10

<asp:Content ContentPlaceHolderID="ContentPlaceHolder2" ID="bbsContent" runat="server">
    <asp:DataList ID="dlbbs" runat="server">
        <ItemTemplate>
        </ItemTemplate>
    </asp:DataList>
</asp:Content>
