我究竟做错了什么？
按下提交按钮后,我收到此错误.

在你的aspx文件中你应该把第一行作为这个:
<%@ Page EnableEventValidation="false" %>
如果你已经有类似的东西 <%@ Page ,只需添加其余=>EnableEventValidation="false" %>
我建议不要这样做.

如果你查看第一行文字,你可以收集你的错误.
此功能验证回发或回调事件的参数是否来自最初呈现它们的服务器控件
你正在动态编辑lstProblems下拉列表,所以当你回发时,ASP.NET说"警告!下拉列表中的条目无效!" 并且吓坏了抛出那个错误.你必须确定关闭事件验证是否是一个好的解决方案,但我会在做之前研究它,因为它背后的想法是让你的网站免费更安全.
这是另一个stackoverflow的答案,可以更好地解释我要做什么: 无效的回发或回调参数.使用'<pages enableEventValidation ="true"/>'启用事件验证

如果您的Page_Load()事件中有代码.尝试添加此:
if (!Page.IsPostBack)
{
//your code here
}

我有一个与数据列表相同的问题我"动态绑定,添加EnableViewState ="false"安静错误消息.我想如果我以编程方式绑定,那么控件正在每个帖子上填充,视图状态不会如果每次回调可能会或者可能不会改变,那么必须保持这一点,这就是为什么我动态绑定它,哈哈.
此错误也可能由<form>主页中的嵌套标记引起,这是不允许的.
<form id="someid"></form>
如果你已经选择了一个模板并从某个地方复制代码,这可能就是原因.
你必须打破<form>标签的嵌套.应该成为以下内容
<form method="" name="form1">
<form method="" name="form2>
</form>
</form>
应该成为
<form method="" name="form1">
</form>
<form method="" name="form2>
</form>
