此页面根本不呈现;它只是空白。我无法弄清楚。我找不到任何HTML错误。

我怀疑它与你在那里的HTML有什么关系。要进行诊断，请创建一个仅包含熊必需品的全新页面。例如，留在母版页中，但删除Inherits和所有其他guff。请尝试以下方法;
<%@Page Language="C#" AutoEventWireup="true" ValidateRequest="false" CodeBehind="MyNewPage.aspx.cs" MasterPageFile="~/Symba/MasterPages/Admin.Master" %>
<asp:Content ID="Content4" ContentPlaceHolderID="head" runat="server">
<%-- Something in the head --%>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="cphMain" runat="server">
bah
</asp:Content>
作为额外的帮助，在页面和母版页的代码隐藏中放置断点以查看它是否正在加载。
一旦有效，请重新添加上面列出的内容，以确定导致问题的原因。它可能是页面代码隐藏的内容。

仔细检查指向母版页文件的链接：
MasterPageFile="~/Symba/MasterPages/Admin.Master"
然后是Content元素的名称：cphMain
答案 2 :(得分：0)
您是否选择此页面作为启动页面。否则，请检查母版页是ContentPlaceHolderID="cphMain"匹配。
