            if (Session["RoleID"] != null)
            {                
                    CustomerID = Request.Form["CustomerID"];                            

                //string CustomerID = Request.Form["Customer.CustomerID"];
                if (CustomerID != null)
                {
                    if (Request.Files.Count > 0)
                    {
                        var file = Request.Files[0];
                        if (file != null && file.ContentLength > 0)
                        {
                            //var fileName = Path.GetFileName(file.FileName);                        
                            var fileExtension = Path.GetExtension(file.FileName);
                            var allowedExtensions = new[] { ".bmp", ".png", ".jpg", "jpeg", ".gif" };
                            if (allowedExtensions.Contains(fileExtension))
                            {
                                //Delete files
                                var pathD = Server.MapPath("~/Avatar/1");
                                var images = Directory.GetFiles(pathD, CustomerID + ".*");
                                for (int i = 0; i < images.Length; i++)
                                    System.IO.File.Delete(Server.MapPath(("~/Avatar/1/") + Path.GetFileName(images[i])));

                                //Up files
                                var fileName = CustomerID + fileExtension;
                                var path = Path.Combine(Server.MapPath("~/Avatar/1/"), fileName);
                                file.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression;
                                file.SaveAs(path);

                                //Session["Avatar"] = fileName;
                            }
