FileBrowserContentProvider for accessing network folder problem

[Rosanna]

Hi all,
I'm trying to develope my own FileBrowserContentProvider for accessing network folder ("\\NetFolderName\\disk1\\folldername..."), but I found a problem: treelist on left works correct and shows the right structure of folder, but when I try to browse one of this element the filelist on right does't refresh, ant still show the root folder elements (it will refresh with the uploadpanel but does't change the content).
Any helps? Thanks...

Here the example code: FileProvider class

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using Telerik.Web.UI.Widgets;

namespace Cep.Print

    {
        //constructor must be present when overriding a base content provider class
        //you can leave it empty
        public FileProvider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag)
            : base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)
        {
        }
