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>
