    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'.
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    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.
