Error upload on server

[Tarkan Haser]

 Hi,

I've done an application that has a radUpload control. If I try the control in my local machine I'm able to upload, save and open the files. But when I publish the application I try to upload a file and I get the 0% uploading state and the file never gets uploaded.

Unhandled Error in Silverlight Application The given key was not present in the dictionary.   at System.ThrowHelper.ThrowKeyNotFoundException()
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at Telerik.Windows.Controls.FileUploader.OnResponse(IAsyncResult asyncResult)

I try to upload allready exists file i give an error message that access denied.
.xaml file:

<telerikInput:RadUpload
    x:Name="RadUploadLogo"
    Margin="0,173,8,0"
    HorizontalAlignment="Right"
    Width="310"

    FilterIndex="0"

    UploadServiceUrl="~/MyUploadHandler.ashx"
    TargetFolder="Images/MusteriLogolari"
    VerticalAlignment="Top" Height="170" Background="#35000000" BorderBrush="White"/>

c# code :

void RadUploadLogo_FileUploadStarting(object sender, FileUploadStartingEventArgs e)
        {
            //e.FileParameters.Add("Authorized", "True");
            string fileName = App.appKullaniciTanimi.cKodHesap;
            int i = e.UploadData.FileName.LastIndexOf('.');
            if (i >= 0 && i < e.UploadData.FileName.Length)
            {
                fileName += e.UploadData.FileName.Substring(i);
            }
            GonderilenDosya = fileName;
            e.UploadData.FileName = fileName;
        }

MyUploadHandler.ashx :

using System;
using System.Web;
using Telerik.Windows.Controls;

namespace QuipusBilisimB2B.Web
{
    public class MyUploadHandler : Telerik.Windows.RadUploadHandler
    {
        public override void ProcessStream()
        {
            string authorized = this.Request.Form["Authorized"];
            bool isOK = !string.IsNullOrEmpty(authorized) && authorized.ToLower() == "true";
            //if (!isOK)
            //{
            //    ////this.CancelRequest();
            //    ////this.Result.Add("Error", "Security token is required.  Please login.");
            //    ////this.AddReturnParam("Error", "Security token is required.  Please login.");
            //    this.AddReturnParam(RadUploadConstants.ParamNameMessage, "Security token is required. Please login.");

            //    string fileName = this.Request.Form[RadUploadConstants.ParamNameFileName];
            //    string filePath = this.GetFilePath(fileName);

            //    this.AddReturnParam(RadUploadConstants.ParamNameSuccess, false);
            //    this.AddReturnParam(RadUploadConstants.ParamNameFileIdent, filePath);
            //    this.AddReturnParam(RadUploadConstants.ParamNameFileName, fileName);
            //    this.AddReturnParam(RadUploadConstants.ParamNameFilePath, filePath);
            //    this.AddReturnParam(RadUploadConstants.ParamNameFinalFileRequest, true);

            //    return;
            //}

            base.ProcessStream();
        }
    }
}
