Webclient eventhandlers not firing ...

C#

I'm using the following code to tie up some eventhandlers to the client.UploadProgressChanged and client.UploadFileCompletedEventHandler

try
{
    WebClient client = new WebClient();
    client.Credentials = new NetworkCredential(txtFTPUserName.Text, txtFTPPassword.Text);
    client.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressChangedEventArgs);
    client.UploadFileCompleted += new UploadFileCompletedEventHandler(UploadFileCompletedEventHandler);
    progBar.Visible = true;
    progBar.Value = 0;
    client.UploadFile(@"ftp://novantconsulting.com/SQLBackups/StrataFrame.bak", @"E:\Strataframe.bak");
 }
catch (Exception exception)
{
    Console.WriteLine(exception);
    throw;
}

Here is the event handler:

private void UploadProgressChangedEventArgs(object sender, UploadProgressChangedEventArgs e)
{
    int percentage = (Convert.ToInt32(e.BytesSent) / Convert.ToInt32(e.TotalBytesToSend)) * 100;

    if (progBar.Value < progBar.Maximum)
    {
        progBar.Value = percentage;
    }
    else
    {
        progBar.Value = 100;
    }
}

Obviously I'm trying to display a status bar but the event never triggers.

Thanks for your help in advance,

What I have tried:

Just what you see in the code ... I Googled the dickens out of it and am starting to think that an async solution is coming my way. I just haven't done any async work yet.
