GeidView打印报表,有列不打印有关问题

GeidView打印报表,有列不打印问题，在线等
gridview 的列有：姓名列，性别列，详细列，删除列
在查看gridview数据是 需要显示 【详细列，删除列】 但是，打印出来的报表中确不需要【详细列，删除列】
我的打印代码如下，求指教：
  Response.Clear();
  Response.Buffer = false;
  Response.Charset = "utf-8";
  Response.AppendHeader("Content-Disposition", "attachment;filename=recordWork.xls");
  Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
  Response.ContentType = "application/ms-excel";
  Response.Write("<meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">");
  this.EnableViewState = false;
  System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
  HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
  GridView1.RenderControl(oHtmlTextWriter);  
  Response.Write(oStringWriter.ToString());
  Response.End();


------解决方案--------------------
在GridView1.RenderControl之前，绑定事件里面进行隐藏。
