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.

在远程服务器(生产、测试、qa、登台等)上遇到这个问题后，而不是在本地开发工作站上，我发现应用程序池配置的RequestLimit不是0。

这导致应用程序池放弃并回复问题中指出的异常。

如果您正在使用gridview，而不是在pageload inside !ispostback中绑定gridview，那么当您单击gridview中的编辑和删除行时，将出现此错误。

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
        bindGridview();
        }

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。

检查绑定控件的数据。一些无效数据破坏了ValidateEvent。

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)
        {      
        }
    }

您可以在.aspx页面中尝试类似的操作

add

EnableEventValidation=“false”

你可以随便问任何问题!
