Question

我正在尝试导出excel网格视图数据。我可以绑定excel中的数据。但是当我打开网格视图时，我丢失了看起来非常糟糕的网格线。我在下面添加了我的代码。

此代码获取我的网格数据并将其导出为excel删除所有网格线我试图谷歌找不到一个突破可以有人帮我这个

  protected void btn_export_Click(object sender, EventArgs e)
    {

        Response.Buffer = true;
        Response.ClearContent();
        Response.ClearHeaders();
        Response.Charset = "";
        string FileName = "Dashboard_FOR_PM" + DateTime.Now + ".xls";
        StringWriter strwritter = new StringWriter();
        HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.ContentType = "application/vnd.ms-excel";
        Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
        grv_dashboard.GridLines = GridLines.Both;

        grv_dashboard.HeaderStyle.Font.Bold = true;
        grv_dashboard.RenderControl(htmltextwrtter);
        Response.Write(strwritter.ToString());

        using (StringWriter sw = new StringWriter())
        {
            using (HtmlTextWriter htw = new HtmlTextWriter(sw))
            {
              Table table = new Table();
        table.BorderStyle = BorderStyle.Solid;
        table.BorderWidth=new Unit(1);
        table.BorderColor = System.Drawing.Color.Black;
        table.GridLines = GridLines.Both;
            }
        }


        strwritter.Write(@"<html xmlns:x=""urn:schemas-microsoft-com:office:excel"">");
        strwritter.Write(@"<head>
                           <xml>
                             <x:ExcelWorkbook> 
                               <x:ExcelWorksheets>
                                   <x:ExcelWorksheet>
                                      <x:WorksheetOptions>
                                         <x:Panes></x:Panes>
                                         <x:Print><x:Gridlines /></x:Print>
                                      </x:WorksheetOptions>
                                    </x:ExcelWorksheet>
                                  </x:ExcelWorksheets>
                                </x:ExcelWorkbook>
                              </xml>
                            </head>");
        Response.End();

看看我之前写过的下面的功能，请询问是否有不清楚的地方，希望有所帮助

public void ToExcel(DataTable dt, string reportName)
    {
        if (dt.Rows.Count > 0)
        {
            string filename = string.Format("{0}.xls", reportName);
            System.IO.StringWriter sw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
            HtmlForm hf = new HtmlForm();

            DataGrid dg = new DataGrid();

            dg.DataSource = dt;
            dg.HeaderStyle.BackColor = Color.Tomato;//change to your own colors
            dg.HeaderStyle.ForeColor = Color.White;//change to your own colors
            dg.BackColor = Color.LightGoldenrodYellow;//change to your own colors
            dg.AlternatingItemStyle.BackColor = Color.PaleGoldenrod;//change to your own colors
            dg.Font.Name = "Tahoma";
            dg.Font.Size = 10;
            dg.GridLines = GridLines.Both;
            dg.BorderColor = System.Drawing.Color.Black;
            dg.BorderStyle = BorderStyle.Solid;
            dg.BorderWidth = new Unit(1);
            dg.DataBind();

            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.Buffer = true;
            HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename);

            HttpContext.Current.Response.Charset = "";
            EnableViewState = false;
            Controls.Add(hf);
            hf.Controls.Add(dg);
            hf.RenderControl(htw);
            HttpContext.Current.Response.Write(sw.ToString());
            HttpContext.Current.Response.End();
        }
    }

将gridview中的数据导出到excel而不会丢失网格线
