导出为excel时 怎么把按钮也输入excel表了
代码： string ss = "";
        HttpResponse res = Page.Response;
        res.Clear();
        res.AddHeader("content-disposition", "attachment; filename=" + DateTime.Now.ToString() + ".xls");
        res.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");  //不转换编码就导出后可能会出现乱码 
        res.ContentType = "application/ms-excel";        System.IO.StringWriter stringWrite = new System.IO.StringWriter();        for (int i = 0; i < DataGrid1.Items.Count; i++)
        {
            ss = "";
            for (int j = 0; j < DataGrid1.Columns.Count; j++)
            {
                if (j > 0)
                {
                    ss += "\t";
                }
                ss += DataGrid1.Items[i].Cells[j].Text;
            }
            stringWrite.WriteLine(ss);
        }
        res.Write(stringWrite);
        //res.Output.Write(stringWrite.ToString());
