这是我的代码

Question

我发誓我和微软有一段爱恨交织的关系。这只是在IE 10中抛出。

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/>

现在，

在@page上我有ValidateRequest =“False”
在Web.config中我有httpRuntime requestValidationMode =“2.0”
我不使用任何Ajax或使用ScriptManager
我正在检查PostBack
删除了组合框代码但它确实使用了AutoPostBack

这是我的代码

Private Sub Page_Init(sender As Object, e As EventArgs) Handles Me.Init

    Try

        Dim User As New UserRole(Me.SiteID, Master.UserName)

        If User.GetLevel(Permissions.Edit) >= Levels.Page Then

            Exit Sub

        End If

    Catch ex As Exception

    End Try

    Response.Redirect("/Manage/Errors/Unauthorized.aspx")

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    If Me.IsPostBack = True Then

        Exit Sub

    End If

    Try

        Dim Item As New PageBase(Me.PageID)

        Me.txtCode.Text = Item.Code

    Catch ex As Exception

        Master.ShowError("Flex encountered a problem reading this page.")

    End Try

End Sub

Private Sub cmbSnippet_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cmbSnippet.SelectedIndexChanged

    If Me.cmbSnippet.SelectedIndex = 0 Then

        Exit Sub

    End If

    Try

        Dim Filename As String = String.Format("/Manage/Editors/Text/Scripts/{0}", Me.cmbSnippet.SelectedValue)

        Me.txtCode.Text = My.Computer.FileSystem.ReadAllText(Server.MapPath(Filename))

        Exit Sub

    Catch ex As Exception

    End Try

    Master.ShowError("Flex encountered a problem reading the snippet.")

End Sub

Private Sub btnOk_Click(sender As Object, e As EventArgs) Handles btnOk.Click

    Try

        Dim Item As New PageBase(Me.PageID)

        Item.Code = Me.txtCode.Text

        If Item.Update = True Then

            Me.ShowUpdateTime()

            Exit Sub

        End If

    Catch ex As Exception

    End Try

    Master.ShowError("Flex encountered a problem modifying this page.")

End Sub

Private Sub btnCancel_Click(sender As Object, e As EventArgs) Handles btnCancel.Click

    Response.Redirect(String.Format("/Manage/Preview.aspx?PageID={0}", Me.PageID))

End Sub

这可能会也可能不会解决问题。

.NET 4及更早版本不知道IE 10是什么。它不在.NET所知的浏览器列表中，所以.NET假定浏览器是无法处理的东西......好吧，真的。 Javascript和cookies，我怀疑更多，搞砸了。所以：

下载：http://www.hanselman.com/blog/content/binary/App_BrowsersUpdate.zip，取自此处：

http://www.hanselman.com/blog/BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition.aspx，

从这里引用：IE10 User-Agent causes ASP.Net to not send back Set-Cookie (IE10 not setting cookies)

提取文件并将它们放入应用程序的App_Browser目录中。重建并查看是否有效。

只有IE10返回无效的回发

这是我的代码
