Uploaded in asp.net 3.5

Can you please share a working sample, for having control of the uploaded files?

I get the next error when I try to compile:

Error    2    Member 'GleamTech.Web.Controls.FileVistaControl.Uploaded' cannot be accessed with an instance reference; qualify it with a type name instead    C:\samples\DotNet35\FileManager\FileVistaExamples\WebForm1.aspx.cs    32    17    FileVistaExamples


This is the code:

namespace GleamTech.FileVistaExamples
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        private static bool areHandlersAdded = false;

        private void FileVistaControl_Uploaded(object sender, GleamTech.Web.Controls.FileVistaUploadedEventArgs e)
        {
            string whichUser = HttpContext.Current.Session["username"].ToString();

            //Get the paths of the uploaded files by walking through UploadedFiles collection
            string filePaths = "";
            foreach (GleamTech.Web.FileTransfer.UploadedFile uploadedFile in e.UploadProgress.UploadedFiles)
                filePaths += uploadedFile.FullPath + ", ";
        }

        protected void Page_Load(object sender, EventArgs e)
        {


            fv.RootFolders[0].Path = Server.MapPath("~/Files");

            if (!areHandlersAdded)
            {
                //fv.Uploaded += new EventHandler<FileVistaUploadedEventArgs>(FileVistaControl_Uploaded);
                fv.Uploaded += FileVistaControl_Uploaded;
                areHandlersAdded = true;
            }
        }   
    }
}

I need to trap the current upload file, and rename it. If the user uploads some.gif I need to rename it into 54321some.gif, so after the callback in the grid I need to see 54321some.gif instead some.gif.

The events are static members (FileVistaControl.Uploaded) but you are trying to access them like instance members (fv.Uploaded).
Below is the most recent code for example 2 (distributed with v1.7):
