我想以这样的格式存储内容，并能够在页面回发后检索。我可以使用隐藏字段吗？如果是，哪种数据类型（不是字符串？）Stringbuilder

是否为每个字段都设置了文本框？您想通过Javascript实现这一点吗？我想说，使用stringbuilder在代码隐藏上更容易实现。以后你打算怎么处理这篇文章？我只想在codebehingd中处理。。像上面给出的格式一样，我有很多格式。稍后，在一个不同的函数中，我想逐个重设每个格式。。然后把它放在面板上显示。你会把所有的格式都存储在数据库中吗？实现这一点的一个简单方法是通过会话变量，您可以在会话中存储每种格式，然后在准备就绪时将它们放在面板中。尽管这有一个警告：记住它的会话，因此它可能会占用服务器上的大量内存。在asp.netVisible属性中，可见性和ViewState不能很好地配合使用。要使控件可见，ViewState要使控件持久化；两个不同的主题您可以在viewstate中保留不可见的控件，例如Yes，但有时在控件中建立visible属性时，viewstate会丢失。解决方法不是使用visible属性，而是使用style=display:none；感谢Andrei的支持，只有在禁用请求验证的情况下，这才有效；否则，ASP.NET将不会很高兴收到HTML标记，因为它会认为这是某种XSS攻击。要修复@Icarus所述的上述问题，您应该首先对文本进行HTML编码，并在您希望向用户显示文本时对其进行解码（如果这是最终目标），最初我收到一个错误，称为Http违规。。经过编码和解码后，它的工作状态良好。。谢谢
