CS0103的问题。。麻烦大家帮帮忙了

Question

前台代码
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PictureBrowseControl.ascx.cs" Inherits="FileUploadUtility.PictureBrowseControl" %>
<input type="hidden" id="FolderPath" runat="server" />
<input type="hidden" id="PictureWidth" runat="server" value="500" />
<table id="PictureBrowseTable" runat="server" width="500">
    <tr>
        <td id="First" runat="server" align="left" width="15%">First&nbsp;</td>
        <td id="Prev" runat="server" align="left">&lt; Previous</td>
        <td id="Next" runat="server" align="right">Next &gt;</td>
    </tr>
    <tr>
        <td colspan="3" align="center" valign="top" ><a id="PictureLink" runat="server" href="" title="Click to show picture in full size" target="_blank"><img id="Picture" runat="server" hspace="5" vspace="5" src="" border="0" width="500" /></a></td>
    </tr> 
    <tr>
        <td id="FileDescription" runat="server" align="left" valign="top" colspan="3"></td>
    </tr>
</table>后台稍微有点长就先不贴了。但在后台里面找不到First、Prev和Next。其他都正常。。我真不知道问题出在哪了

Answer 1

 <td id="First" runat="server" align="left" width="15%">First&nbsp;</td>
  <td id="Prev" runat="server" align="left">&lt; Previous</td>
  <td id="Next" runat="server" align="right">Next &gt;</td>
红色部分为什么要要，table不是添加了runat="server"，
很久没整BS呢？我学习一下

Answer 2

<td id="First" runat="server" align="left" width="15%">First&nbsp;</td>
  <td id="Prev" runat="server" align="left">&lt; Previous</td>
  <td id="Next" runat="server" align="right">Next &gt;</td>
？？？你去看看引用这个Control 的 在页面头部注册了没有

Answer 4

复制的话，控件没有在.cs.design里面注册，所以报错，
把之前页面的cs.design也复制过来

Answer 5

没有这个文件啊。。何况。就那三个有问题。但FileDescription什么的就没问题。

Answer 6

疯了。。在后台FileDescription就可以显示出HtmlTableCell PictureBrowseControl.FileDescription
那三个就不行

Answer 7

我拷贝你的代码测试在VS2010里面是没问题的。你可以先把文件备份，删除新建一次试试
或者把你完整的ascx,cs文件发来看看
