Repeater控件的使用 浅析Repeater控件的使用 (原样导出和动态显示/隐藏Repeater中的列)

DataTable dt = ViewState["DtDatat"] as DataTable; //Repeater绑定的数据源
      this.Repeater1.DataSource = dt;
      this.Repeater1.DataBind();
      DisplayDetailCol(false);
      //使用流方式导出Excel
      HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
      HttpContext.Current.Response.ContentType = "application/ms-excel";
      HttpContext.Current.Response.Charset = "gb2312";
      HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + Context.Server.UrlPathEncode("excel名称.xls")); //解决中文乱码问题
      StringWriter sw = new StringWriter();
      HtmlTextWriter htw = new HtmlTextWriter(sw);
      Repeater1.RenderControl(htw);
      HttpContext.Current.Response.Write(sw.ToString());
      HttpContext.Current.Response.End();

 foreach (RepeaterItem item in this.Repeater1.Controls)
    {
      if (item.ItemType == ListItemType.Header)
      {
        item.FindControl("panelDetail").Visible = b;
      }
      if (item.ItemType == ListItemType.Item)
      {
        item.FindControl("lbtnDetail").Visible = b;
      }
    }
