错误消息,“控件集合无法修改,因为控件包含代码块”

标签: asp.net user-controls umbraco

我在以前工作正常的页面上收到此错误,事实上我最近对该页面所做的唯一更改是添加另一个asp:TextBox和asp:RequiredFieldValidator控件。

页面上已经有很多ASP.NET控件,所以我看不出为什么这些额外的控件会产生影响,无论如何我会发布下面的代码,希望你能看到错误是什么:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MeetingGenerator.ascx.cs" 
Inherits="usercontrols_MeetingGenerator" %>

它是通过从jQuery选择器中删除代码块并将它们更改为name * = selectors来进行排序的。将&lt;%=更改为&lt;%#并没有解决问题,希望选择器更改适用于其他人。

尝试在jQuery脚本中更改&lt;%= to&lt;%#。查看this article
