Displaying a PDF uploaded to the server

[berger]

Hey I am having some trouble displaying a PDF in a new window that is uploaded to the server by the client. When I try and display the copied pdf file I just get a blank window. I used the calendar demo to start with. If you want me to include all the calendar code I will, but for the I have just included the problem area. I am however able to display the pdf if I don't copy it to a new folder eg: hard code the ORIGINAL file path to the URL of the window.

Mark-up:

<form runat="server">
        <ext:ResourceManager runat="server" Namespace="ExchNotPOC"  />
        
        <ext:Window runat="server" ID="PDFVIEW" Hidden="true" Modal="true"/>
</form>

Java Script that calls the server:

 add: function (win, rec) {

            var v = win.FileUp.extractFileInput().value
            ExchNotPOC.direct.FileUploadTest(v);
            rec.data.Url = v;
            ExchNotPOC.getStore().add(rec);
            ExchNotPOC.ShowMsg('Event ' + rec.data.Title + ' was added');
            win.hide();
        },

Code Behind:

        [DirectMethod]
        public void FileUploadTest(string v)
        {
            string fileToUpLoad = v;

            if(!String.IsNullOrEmpty(fileToUpLoad))
            {
                try
                {
                    FileStream fs = new FileStream(@fileToUpLoad, FileMode.Open);
                  
                    string fn = System.IO.Path.GetFileName(fileToUpLoad);
                    string saveLocation = Server.MapPath("Data") + "\\" + fn; 
                    FileStream copied = new FileStream(@saveLocation, FileMode.Create);
                    fs.CopyTo(copied);
                    fs.Close();
                    copied.Close();

                    Ext.Net.Window win = new Ext.Net.Window();
                    win.FindControl("PDFVIEW");
                    win.Height = 500;
                    win.Width = 1000;
                    win.Loader = new ComponentLoader
                    {
                        Url = saveLocation,
                        Mode = LoadMode.Frame,
                        AutoLoad = true,
                        LoadMask =
                        {
                            ShowMask = true
                        }
                    };
                    win.Hidden = false;
                    win.Render(this.Form);
                }
                catch(Exception ex)
                {

                }
            }   
        }

Thanks!
