一、Repeater數據原樣導出

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();

二、動態顯示/隱藏Repeater中的列

 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;      }    }

三、下載的excel顯示成html格式

     需要將<table>標簽添加到HeaderTemplate和FooterTemplate中  

四、導出的Excel數據為空或則數據都縮到一列

       不要設置列的寬度為百分比
