AsyncFileUpload issue on remote server

Question

On local server - everything is working fine (upload + JS alert).
On remote server - nothing is hapening, i think it is not firing.

This is the code:
<ajaxToolkit:AsyncFileUpload ID="AsyncFileUpload_picture" runat="server" OnClientUploadStarted="showUploadStartUpdateProgress" OnUploadedComplete="AsyncFileUploadUploadedComplete"
                                                            OnClientUploadComplete="showUploadEndUpdateProgress" OnClientUploadError="showUploadEndUpdateProgress"
                                                            Width="200" />
protected void AsyncFileUploadUploadedComplete(object sender, AsyncFileUploadEventArgs e)
        {
            var asyncFileUpload = (AsyncFileUpload)sender;
            string columnName = Convert.ToString(asyncFileUpload.ClientID);

            if (asyncFileUpload.HasFile)
            {
                //upload file here

                ScriptManager.RegisterStartupScript(this.Page, GetType(), "showAlert",
                   string.Format("alert('file uploaded');"), true); //alert after upload
            }
        }

Please advise
Thanks

Only upload is not working or all AJAX features failing?

It is difficult to provide you with a solution with this kind of code and description. What do you mean by nothing happens something must be going on: Check if the request is being made from client to the remote server can be easily checked with the help of the developer tools. Also check if your javascript is not in error state you can check for any javascript errors on the page in the console window same is provided by developer tools. Regards AJ
