Question

我们在其中一个使用.NET 2.0构建的应用程序中有一个报表生成器

每当我们尝试在IE 10中运行报告时，我们会收到服务器错误，并显示以下消息：

Invalid postback or callback argument.  Event validation is enabled using 
<pages enableEventValidation="true"/> in configuration or 
<%@ Page EnableEventValidation="true" %> in a page.  
For security purposes, this feature verifies that arguments to postback or callback 
events originate from the server control that originally rendered them.  If the data is 
valid and expected, use the ClientScriptManager.RegisterForEventValidation method in 
order to register the postback or callback data for validation. 
Description: An unhandled exception occurred during the execution of the current web 
request. Please review the stack trace for more information about the error and where it 
originated in the code.

仅当我们在IE 10中运行报告时才会发生此错误。

如果我们使用任何其他IE版本或任何其他浏览器，我们不会收到任何错误，报告运行正常。

根据Microsoft文档，这在.NET 3及更高版本上得到了解决。但我们已经拥有.NET 3.5，但仍无法在IE 10上运行。

这是页眉：

<%@ Page EnableEventValidation="true" Language="VB"  %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
    Client_Id.Value = Request.QueryString("Client_Id")
    Project_Id.Value = Request.QueryString("Project_Id")
    System_Id.Value = Request.QueryString("System_Id")
    Report_Page_Heading.Text = Replace(Request.QueryString("H"), "'", "")


    PartExportFields.SelectParameters.Add("Client_Id", Replace(Client_Id.Value, "'", ""))
    PartExportFields.SelectParameters.Add("Project_Id", Replace(Project_Id.Value, "'", ""))
    PartExportFields.SelectParameters.Add("System_Id", Replace(System_Id.Value, "'", ""))

    SavedCustomReports.SelectParameters.Add("Client_Id", Replace(Client_Id.Value, "'", ""))
    SavedCustomReports.SelectParameters.Add("Project_Id", Replace(Project_Id.Value, "'", ""))
    SavedCustomReports.SelectParameters.Add("System_Id", Replace(System_Id.Value, "'", ""))

    ListBox1.SelectedValue = Request.QueryString("edit")
End Sub

Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)

End Sub

Protected Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)

End Sub

Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)

    Page.ClientScript.RegisterForEventValidation("Client_Id", Replace(Client_Id.Value, "'", ""))
    Page.ClientScript.RegisterForEventValidation("Project_Id", Replace(Project_Id.Value, "'", ""))
    Page.ClientScript.RegisterForEventValidation("System_Id", Replace(System_Id.Value, "'", ""))
    MyBase.Render(writer)
End Sub    
</script>

任何想法或帮助都会很棒。

提前致谢！

Answer 1

我遇到了与IE 10类似的问题.IE 10与webforms不相称（具有讽刺意味的是微软技术不适用于微软技术）。见link。您可以应用一些机器范围的补丁来解决一些问题。此外，使用一些Microsoft Ajax的东西在IE 10中根本不起作用。我能够解决的唯一方法是发送一个告诉IE以IE 9模式运行页面的标题。

Answer 2

我发现的唯一解决方案是运行Windows Update。

这下载了IE的所有必要修复程序。

之后错误消失了。
