Answer 1

1. 确保您的 Page 指令中有 AutoEventWireup="true"

2. 确保您没有收到错误，无论是客户端还是服务器端。附加一个调试器并逐步检查您的代码以确保这一点

3. 您的按钮无法点击，因为它是不可见的，所以我假设您通过 JavaScript 调用点击。要为链接按钮执行此操作，您需要评估其 href 属性：eval(document.getElementById("<%=Aspx_LinkButton_DocumentVersion.ClientID%>").getAttribute("href"));

4. 确保所有网络资源请求都通过（即 200 或 300 秒状态代码）。这就是获取 MS AJAX 框架的方式。

5. 确保您的脚本管理器是 <form> 标记之后的第一个控件，并且所有后续启用 AJAX 的内容也在 <form> 内。
