急！关于ASP.NET控件的小问题
<head runat ="server">
<title>信息发布页</title>
</head>
<body runat ="server">
<div class="top">
<asp:Image SkinID="logoImage" ID="Image1" runat ="server"/>
</div>
<table style="width: 405px; height: 279px" runat ="server">
<tr >
<td >
<asp:ImageButton ID="ImageButton1" ImageUrl="~/images/1.jpg" runat="server" /></td>
<td>
<asp:ImageButton ID="ImageButton2" ImageUrl="~/images/2.jpg" runat="server" /></td>
<td style="width: 132px">
<asp:ImageButton ID="ImageButton3" ImageUrl="~/images/3.jpg" runat="server" /></td>
</tr >
<tr>
<td>
<asp:ImageButton ID="ImageButton4" ImageUrl="~/images/4.jpg" runat="server" /></td>
<td>
<asp:ImageButton ID="ImageButton5" ImageUrl="~/images/5.jpg" runat="server" /></td>
<td style="width: 132px">
<asp:ImageButton ID="ImageButton6" ImageUrl="~/images/6.jpg" runat="server" /></td>
</tr>
<tr>
<td>
<asp:ImageButton ID="ImageButton7" ImageUrl="~/images/7.jpg" runat="server" /></td>
<td>
<asp:ImageButton ID="ImageButton8" ImageUrl="~/images/8.jpg" runat="server" /></td>
<td style="width: 132px">
<asp:ImageButton ID="ImageButton9" ImageUrl="~/images/9.jpg" runat="server" /></td>
</tr>
</table>
</body>
我家有RUNat=server怎么运行报错ImageButton1”必须放在具有 runat=server 的窗体标记内答案：在body内部添加form表单，并且添加属性 runat="server",table（页面内容）要放在form（带有runat="server"）内。
其他：缺少服务器form标签
上一个：ASP.NET与sql server 2008建立联系，调试老是出错，请高手指教！
下一个：.net 做类似贴吧的系统
