We won't know how many assoicated files are included during the upload.  Therefore if it has a validateoption that can pre-filter the filename in the file dialog box that would be a great.

Thanks,

protected void Uploader_FileUploaded(object sender, UploaderEventArgs args)

   if (sender == this.upPrimary)

      string filename = args.FileName.Substring(0, args.FileName.Length - 4);

         upAssoicates.DialogFilter = string.Format("Assoicated Point Files|{0}.CB*;{0}.EC*;{0}.FDH;{0}.FM*;{0}.S0*;{0}.LP2", filename);

         upAssoicates.InsertButton.Enabled = true;
