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.

如果您使用Ajax更新面板。添加<Triggers>标签，并在其中使用<asp:PostBackTrigger…/>触发按钮或控件导致回发

问题是ASP。NET不会知道这个额外的或已删除的列表项。你有很多选择(如下所示):

禁用eventvalidation(这是个坏主意，因为你损失了一点安全性，而代价却很小)。使用ASP。NET Ajax UpdatePanel。(如果你添加或删除列表框，将列表框放在更新面板中并触发更新。通过这种方式，viewstate和相关字段得到更新，eventvalidation将通过。) 忘记客户端，使用经典的回发并添加或删除listitems服务器端。

3:我改变了我的按钮类型在网格列从“PushButton”到 “LinkButton”。它工作! ("ButtonType="LinkButton")我认为如果你可以把你的按钮换成其他的其他控件如“LinkButton” 在这种情况下，它会正常工作。

我希望我能给你投票，阿米尔(唉，我的代表太低了。)我只是有这个问题，改变这个工作就像一个冠军在我的网格视图。稍微提一下，我认为有效的代码是:ButtonType="Link"

我怀疑这是因为当你点击“编辑”时，你的编辑变成了“更新”和“取消”，然后在提交时又变成了“编辑”。这些变化的控件让。net很不舒服。

The following example shows how to test the value of the IsPostBack property when the page is loaded in order to determine whether the page is being rendered for the first time or is responding to a postback. If the page is being rendered for the first time, the code calls the Page.Validate method. The page markup (not shown) contains RequiredFieldValidator controls that display asterisks if no entry is made for a required input field. Calling Page.Validate causes the asterisks to be displayed immediately when the page is rendered, instead of waiting until the user clicks the Submit button. After a postback, you do not have to call Page.Validate, because that method is called as part of the Page life cycle.

 private void Page_Load()
    {
        if (!IsPostBack)
        {      
        }
    }

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。

这里没有提到的另一种方法是子类化ListBox

Ie.

public class ListBoxNoEventValidation : ListBox 
{
}

如果你子类化了system . web . ui . supportsevenvalidation属性，除非你显式地把它添加回来，否则它永远不会调用验证例程。这对任何控件都有效，而且是我发现的在一个控件的基础上“禁用”它的唯一方法(即，不是页面级别)。
