AJAX :: Capture The Full File Path From Async File Uploader Control?

I have an Async File Uploader control inside a Repeater which is inside an update panel. Now,I am uploading the file into ftp,so I am not uploading the video file,using SaveAs() method. For uploading the file in ftp,I have this UploadFile method which takes these four parameter:FileName, UploadPath, FTPUser, FTPPassword.Now this FileName,I have to send the full file path. My UploadComplete event looks like this:

<pre lang="cs">protected void AsyncVideoUpload_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{//VideoPath is a session variable
VideoPath = string.Empty;
if (AsyncVideoUpload.HasFile)
{
// string filepath = AsyncVideoUpload.PostedFile.FileName;
string filepath = e.filename;//above two captures only the file name,but I want the total path,like c:/MyDocuments/...
UploadFile(filepath, "ftp://172.20.117.102","test","Value*12");
VideoPath = AsyncVideoUpload.PostedFile.FileName;
}
}</pre>
