We just upgraded our web server from Windows Server 2003 R2 with IIS 6.? to Windows Server 2012 R2 with IIS 8.5.9600.

We also upgraded the Telerik controls from 2010.3.1317.35 to 2016.2.607.35.

A very simplified page example is:

<body>

<form id="form1" runat="server">

<asp:HiddenField ID="hfToolId" runat="server" />

<asp:HiddenField ID="hfTempDirectory" runat="server" />

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true">

</telerik:RadScriptManager>

<asp:Button ID="Button1" runat="server" Text="Button" />

<div>

<telerik:RadFileExplorer ID="rfeDocs" runat="server" OnClientFileOpen="OnClientFileOpen"

DisplayUpFolderItem="false" EnableCreateNewFolder="false" Width="100%">

<Configuration SearchPatterns="*.*" MaxUploadFileSize="104857600" />

</telerik:RadFileExplorer>

</div>

</form>

</body>

Its associated code behind is:

01.Partial Class _Default

02. Inherits System.Web.UI.Page

03.

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

05. SetupFileExplorer()

06. End Sub

07.

08. Private Sub SetupFileExplorer()

09. Dim controls As Telerik.Web.UI.FileExplorer.FileExplorerControls = 0

10. Dim di As IO.DirectoryInfo

11. Dim newTempDirectory As String = String.Empty

12. Dim path(0) As String

13. Dim s = CType(rfeDocs.FindControl("splitter"), RadSplitter)

14. Dim toolId As Integer

15.

16. If IsNumeric(hfToolId.Value) Then

17. toolId = CInt(hfToolId.Value)

18. ElseIf Request.QueryString("equipmentid") IsNot Nothing Then

19. toolId = CInt(Request.QueryString("equipmentid"))

20. Else

21. toolId = 0

22. End If

23.

24. For Each item As RadToolBarItem In rfeDocs.ToolBar.Items

25. If TypeOf item Is RadToolBarButton Then

26. CType(item, RadToolBarButton).CausesValidation = False

27. End If

28. Next

29.

30. If toolId > 0 Then

31. path(0) = Page.ResolveUrl("~/Tools/" & toolId.ToString())

32. ElseIf Not String.IsNullOrEmpty(hfTempDirectory.Value) Then

33. path(0) = Page.ResolveUrl("~/Tools/" & hfTempDirectory.Value)

34. Else

35. newTempDirectory = Request.LogonUserIdentity.Name().Split(New Char() {"\"c})(1) & Now.Ticks

36. hfTempDirectory.Value = newTempDirectory

37. path(0) = Page.ResolveUrl("~/Tools/" & newTempDirectory)

38. End If

39.

40.

41. di = New IO.DirectoryInfo(Server.MapPath(path(0)))

42.

43. If Not di.Exists Then

44. di.Create()

45. End If

46.

47. rfeDocs.Configuration.ViewPaths = path

48. rfeDocs.Configuration.UploadPaths = path

49. rfeDocs.Configuration.DeletePaths = path

50.

51. rfeDocs.Upload.InitialFileInputsCount = 1

52. rfeDocs.InitialPath = path(0)

53. rfeDocs.Upload.EnableFileInputSkinning = False

54. rfeDocs.Grid.MasterTableView.TableLayout = GridTableLayout.Fixed

55. rfeDocs.Grid.ClientSettings.AllowRowsDragDrop = False

56. rfeDocs.Grid.ClientSettings.Resizing.ResizeGridOnColumnResize = True

57. rfeDocs.VisibleControls = FileExplorer.FileExplorerControls.Toolbar Or FileExplorer.FileExplorerControls.Grid

58.

59. End Sub

60.

61. Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

62. 'just to force page postback

63. End Sub

64.End Class

The user would normally fill out a form, click a save button (which would cause the postback), then upload files via the RadFileExplorer control. Prior to the server upgrades, the code worked fine, after the upgrades, the page fails on line 51 in the code behind. The rfeDocs.Upload object/property is null/nothing.

Is there anything incorrect with the page for the new version?

Thank you,

James

Hi James,

Several releases ago we made RadAsyncUpload default upload control in RadFileexplorer, as RadUpload is obsolete now. Nevertheless, you can still use it by applying the following configuration:

<telerik:RadFileExplorer ID="rfeDocs" runat="server" OnClientFileOpen="OnClientFileOpen"

DisplayUpFolderItem="false" EnableCreateNewFolder="false" Width="100%">

<Configuration SearchPatterns="*.*" MaxUploadFileSize="104857600" EnableAsyncUpload="false" />

</telerik:RadFileExplorer>
