Is this normal?

or am I doing something wrong?

 UploadAttachments uploader = new UploadAttachments();
                            uploader.ShowCheckBoxes = true;
                            uploader.ShowActionButtons = true;
                            uploader.ShowFileIcons = true;
                            uploader.ShowRemoveButtons = true;
                            uploader.MaxFilesLimit = Int32.Parse(Parameter.GetParameter("Upload", "MaxFilesLimit"));
                            uploader.ValidateOption.MaxSizeKB = Int32.Parse(Parameter.GetParameter("Upload", "MaxSizeKB"));
                            uploader.ValidateOption.AllowedFileExtensions = Parameter.GetParameter("Upload", "AllowedFileExtensions");                    
                            uploader.UploadingMsg = Translation.getTranslation("Uploader_UploadingMsg");
                            uploader.UploadProcessingMsg = Translation.getTranslation("Uploader_UploadProcessingMsg");
                            uploader.ActionButtonText = Translation.getTranslation("Uploader_ActionButtonText");
                            uploader.InsertText = Translation.getTranslation("Uploader_InsertText");
                            uploader.DirtyText = Translation.getTranslation("Uploader_DirtyText");
                            uploader.RemoveButtonBehavior = AttachmentItemBehavior.Delete;

                            uploader.ID = String.Format("answer{0}{1}", pagedetail.Question.QuestionLabelName, genPage.UniqueId);
