淺析Repeater控件的使用 (原樣導出和動態顯示/隱藏Repeater中的列)

DataTable dt = ViewState["DtDatat"] as DataTable; //Repeater綁定的數據源
 this.Repeater1.DataSource = dt;
 this.Repeater1.DataBind();
 DisplayDetailCol(false);
 //使用流方式導出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名稱.xls")); //解決中文亂碼問題
 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;
 }
 }
