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;      }    }
