将ListView导出为PDF

Question

我正在创建一个应用程序，我成功将ListView导出为PDF格式。但是我的PDF有一些问题：PDF的格式非常糟糕。

看看：

我使用以下代码导出为PDF：

protected void ExportToPdf_Click(object sender, EventArgs e)
    {
        string File = "PDFCollegeDetails";
        var result = GetData().ToList();
        ExportListToPDF(result, File);           
    }

    private void ExportListToPDF(List<CollegeDetail> result, string File)
    {
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=CollegeDetailsInPdf.pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        GridView gridView = new GridView();
        gridView.DataSource = result;
        gridView.DataBind();
        gridView.RenderControl(hw);
        StringReader sr = new StringReader(sw.ToString());
        Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 50f, 50f);
        HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
        PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        pdfDoc.Open();
        htmlparser.Parse(sr);
        pdfDoc.Close();
        Response.Write(pdfDoc);
        Response.End();
        gridView.AutoGenerateColumns = true;
    }

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=ZoneWiseReport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridViewZoneReport.AllowPaging = false;
this.BindGridView();
GridViewZoneReport.DataBind();
GridViewZoneReport.RenderControl(hw);
GridViewZoneReport.HeaderRow.Style.Add("width", "15%");
GridViewZoneReport.HeaderRow.Style.Add("font-size", "10px");
GridViewZoneReport.Style.Add("text-decoration", "none");
GridViewZoneReport.Style.Add("font-family", "Arial, Helvetica, sans-serif;");
GridViewZoneReport.Style.Add("font-size", "8px");
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A2, 7f, 7f, 7f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
