asp.net gridview 导出Excel 分页？？？

Question

• 这是我现在用的方法

  /// 导出方法
      /// </summary>
      /// <param name="GridView"></param>
      /// <param name="filename">保存的文件名称</param>
      private void ExportGridViewForUTF8(GridView GridView, string filename)
      {
  
          string attachment = "attachment; filename=" + filename;
  
          Response.ClearContent();
          Response.Buffer = true;
          Response.AddHeader("content-disposition", attachment);
  
          Response.Charset = "UTF-8";
          Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
          Response.ContentType = "application/ms-excel";
          System.IO.StringWriter sw = new System.IO.StringWriter();
  
          HtmlTextWriter htw = new HtmlTextWriter(sw);
          GridView.RenderControl(htw);
  
          Response.Output.Write(sw.ToString());
          Response.Flush();
          Response.End();
      }
  

  

• 这是我用这个方法实现的效果

• 现在我想让他把后面分页的5224条数据，全显示在一个Excel表里

• 应该怎么写啊 大佬们

Answer 1

如果你不想去掉网页的分页  可以向下面 加上前两句代码  重新从数据源查一遍数据 ，gridview 的属性allowpaging 设为false  不会影响网页分页


    private void ExportGridViewForUTF8(GridView GridView1, string filename)
{

    GridView1.AllowPaging = false;

    bind();//重新为gridview 绑定数据


    string attachment = "attachment; filename=" + filename;

    Response.ClearContent();
    Response.Buffer = true;
    Response.AddHeader("content-disposition", attachment);

    Response.Charset = "UTF-8";
    Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
    Response.ContentType = "application/ms-excel";
    System.IO.StringWriter sw = new System.IO.StringWriter();

    HtmlTextWriter htw = new HtmlTextWriter(sw);
    GridView1.RenderControl(htw);

    Response.Output.Write(sw.ToString());
    Response.Flush();
    Response.End();
}

有很多方法，但是就你现有代码来说，最省事的办法，就是打开一个页面，不要分页地加载全部的数据，再导出。
