c# - ASP :button onclick doesn't fire and page only refreshes

Question

这是我的按钮的 aspx 代码:

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

下面是代码隐藏文件中的 onclick 事件函数:

public void Button1_Click(object sender, EventArgs e)
{
    lblOutput.Text = txtFirstName.Text;
}

或者，我还在 onclick 函数中使用了它，以查看问题是否出在函数中的脚本而不是按钮本身:

public void Button1_Click(object sender, EventArgs e)
{
    Response.Redirect("http://www.google.com");
}

不幸的是，这也不起作用。所以问题可能是点击按钮时出了问题，对吧？

后面的代码已正确链接，因为 page_load 中的其他函数工作正常。

单击我的按钮时发生的所有事情是页面刷新。老实说，我不确定我是否可以称之为刷新，from 中的值仍然存在，页面只是跳回顶部，没有其他任何事情发生。

我还尝试创建第二个按钮，其 ID 和 onclick 名称略有不同，但页面的行为仍然相同。我在这里完全不知所措。我没有在谷歌上找到任何有帮助的东西。

编辑:这是完整的 asp 文件。我们将 ektron 用作 CMS，因此也有一些奇怪的代码。在任何人询问之前，是的，它在表单标签中。

编辑 2: 这是在运行时查看页面源时页面上的标签，我相信可能是由主文件提供的。正如我之前所说，我们使用 ektron cms。表单标签会不会有问题？

<form method="post" action="/urm/intake/" id="aspnetForm" onsubmit="if(&#39;undefined&#39; == typeof Ektron || !Ektron.FormBlock || !typeof Ektron.FormBlock.validate  || Ektron.FormBlock.validate(this)){$ektron(&#39;input[type=submit]&#39;).attr(&#39;disabled&#39;,&#39;disable&#39;);return true;}else{return false;}">

Answer 1

想通了。 CMS 是错误的。我正在使用 Ektron CMS 提供的 URL 在线查看页面。更改模板

<CMS:FormBlock ID="FormBlock1" runat="server" DynamicParameter="ekfrm" />

到内容 block 固定它。 ektron CMS 中的表单 block 导致了问题。
