I just can't seem to get renaming a file during upload to work. I have tried to follow all the examples including the one here:

Here is the code I currently have:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="radup.aspx.vb" Inherits="radup" %>
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<head runat="server">
    <form id="form1" runat="server">
        <telerik:radcodeblock id="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            var $ = $telerik.$;
            function onClientFileUploaded(radAsyncUpload, args) {
                var $row = $(args.get_row());
                var inputName = radAsyncUpload.getAdditionalFieldID("TextBox");
                var inputType = "text";
                var inputID = inputName;
                var input = createInput(inputType, inputID, inputName);
                var label = createLabel(inputID);
            function createInput(inputType, inputID, inputName) {
                var input = '<input type="' + inputType + '" id="' + inputID + '" name="' + inputName + '" />';
                return input;
            function createLabel(forArrt) {
                var label = '<label for=' + forArrt + '>File info: </label>';
                return label;
        <br />
        <telerik:RadAsyncUpload runat="server" id="RadAsyncUpload1" TargetFolder="~/upload" OnClientFileUploaded="onClientFileUploaded"></telerik:RadAsyncUpload>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" />
        <br />
    <telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

Imports System
Imports System.IO
Imports System.Collections
Imports System.Data
Imports System.Data.SqlClient
Imports Telerik.Web.UI
Partial Class radup
    Inherits System.Web.UI.Page
    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
        For Each f As UploadedFile In RadAsyncUpload1.UploadedFiles
            Dim fileName As String = Guid.NewGuid().ToString + f.GetName()
            Dim title As String = f.GetFieldValue("TextBox")
            f.SaveAs(fileName & ".XML", True)
    End Sub
End Class

Here is my error:

Could not find file 'C:\Websites\edibletastyprints\htdocs\App_Data\RadUploadTemp\0bbbftff.g4z'.

As always, any help much appreciated.

Hi Allan,

I setup a working page from your sample code, please review the attachment. Keep in mind that when you manually save the files the TargetFolder property should not be set.
