无效的回发或回调参数。使用'<pages enableEventValidation="true"/>'启用事件验证

当我从客户端返回一个页面时，我得到以下错误。我有JavaScript代码，修改asp:ListBox在客户端。

我们如何解决这个问题?

错误详情如下:

Server Error in '/XXX' Application.

在将常规ASPX页面转换为Content页面时，我们也遇到了同样的问题。

有此问题的页面在其中一个Content部分内有一个</form>标记，因此在运行时呈现了两个表单结束标记，从而导致了此问题。从页面中删除额外的表单结束标记解决了此问题。

Ajax UpdatePanel可以做到这一点，我认为这是最简单的方法，忽略Ajax回发开销。

在本例中，将id添加到网格的RowDataBound中的按钮。它会解决你的问题。

以上这些方法对我都没用。经过更多的挖掘，我意识到我忽略了2个表单应用在页面上，这是导致问题的原因。

<body>
<form id="form1" runat="server">
<div>
        <form action="#" method="post" class="form" role="form">
        <div>
        ...
        <asp:Button ID="submitButton" runat="server"
        </div>
</div>
</body>

注意，最近ASP。NET已经开始考虑iframes在一个表单标签中包含一个表单标签在iframe文档本身是一个嵌套框架。为了避免这个错误，我不得不将iframe移出form标签。

供参考，我有同样的错误消息的问题，这是我在同一页上有2个表单标签。一个在母版页，一个在页面本身。一旦我删除了第二个形式标签对，问题就消失了。

最好的选择是使用隐藏字段，不禁用事件验证，也改变每个列表框，下拉列表选择与runat服务器属性
