只有IE10返回Invalid Postback

Question

我發誓我與微軟有一種愛恨關係。這被拋出只能在IE 10

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

現在，

1. 在@page我有ValidateRequest = 「假」

2. 在Web.config我的httpRuntime requestValidationMode =「2.0」

3. 我沒有使用任何Ajax或有一個ScriptManager

4. 我檢查回傳

5. 刪除組合框的代碼，但它使用的AutoPostBack

這裏是我的代碼

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

這可能會或可能不會解決問題。

.NET 4和更早版本不知道IE 10是什麼。它不在.NET知道的瀏覽器列表中，所以.NET假定瀏覽器是無法處理的東西......好吧，真的。 Javascript和cookies，我懷疑更多，搞砸了。所以：

這是從這裏引用：IE10 User-Agent causes ASP.Net to not send back Set-Cookie (IE10 not setting cookies)

解壓縮文件，並把它們在你的應用程序的App_Browser目錄。重建並看看是否有效。
