Question

I like to convert GridView to PDF using iTextSharp.dll.However I have cyrillics characters in my GridView and they don’t appear in the pdf document.Here is the code I am using

        Response.Clear(); //this clears the Response of any headers or previous output
        Response.Buffer = true; //ma
        Response.ContentType = "application/pdf";
        iTextSharp.text.pdf.BaseFont arial = iTextSharp.text.pdf.BaseFont.CreateFont(@"C:\Windows\Fonts\arial.ttf", "Identity-H", iTextSharp.text.pdf.BaseFont.EMBEDDED);
        Response.AddHeader("content-disposition", "attachment;filename=Pregled.pdf");


        Response.Cache.SetCacheability(HttpCacheability.NoCache);

        StringWriter sw = new StringWriter();

        HtmlTextWriter hw = new HtmlTextWriter(sw);

        gvTekovenKorisnik.RenderControl(hw);

        StringReader sr = new StringReader(sw.ToString());

        Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);


        HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

        PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

        pdfDoc.Open();

        htmlparser.Parse(sr);

        pdfDoc.Close();

        Response.Write(pdfDoc);

        Response.End();

I read that I have to change the baseFont but I don’t know where to put it in code after changing it.Can somebody help me?

I propose the following variant

protected void btnGridViewToPdf_Click(object sender, EventArgs e)
    {
        GridViewToPdf();
    }
        private void GridViewToPdf()
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "attachment;filename=Reestr.pdf");
            //подключаепм шрифт
            String FONT_LOCATION = Server.MapPath("~/fonts/arial.ttf");
            BaseFont baseFont = BaseFont.CreateFont(FONT_LOCATION, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            iTextSharp.text.Font font = new iTextSharp.text.Font(baseFont, iTextSharp.text.Font.DEFAULTSIZE, iTextSharp.text.Font.NORMAL);
            //подключили
            //создаем PDF документ
            Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
            PdfWriter.GetInstance(pdfDoc, Response.OutputStream);  
            pdfDoc.Open();
            //Создадим таблицу 
            PdfPTable table = new PdfPTable(2);
            //Создадим заголовок
            table.AddCell(new PdfPCell(new Paragraph("\nРеестр закупок\n\n", font)) { Colspan = 2, HorizontalAlignment=1 });
            //столбцы шириной в пропорции - 1/15 и 14/15
            float[] widths = new float[] { 1f, 14f };
            table.SetWidths(widths);
            //оставлять зазор до и после таблицы
            table.SpacingBefore = 10f;
            table.SpacingAfter = 10f;
            PdfPCell cell = new PdfPCell(new Phrase());
            cell.Padding = 5;
            cell.Colspan = 3;
            foreach (GridViewRow row in GridView1.Rows)
            {
                if (row.RowType == DataControlRowType.DataRow)
                {
                    Label _lblN = row.FindControl("lblN") as Label;
                    String lblN = _lblN.Text.ToString();
                    Label _lblnameOrder = row.FindControl("lblnameOrder") as Label;
                    String lblnameOrder = _lblnameOrder.Text.ToString();
                    Label _lblsummaOrder = row.FindControl("lblsummaOrder") as Label;
                    String lblsummaOrder = _lblsummaOrder.Text.ToString();

                    ///
                    PdfPCell cell1 = new PdfPCell(new Phrase(lblN, font)) { HorizontalAlignment = 1, VerticalAlignment= 1 };
                    table.AddCell(cell1);
                    ///

                    //table.AddCell(new PdfPCell(new Paragraph(lblN, font)) { HorizontalAlignment = 1 });

                    table.AddCell(new PdfPCell(new Paragraph("Наименование закупки: \n" + lblnameOrder + "\nСумма: \n" + lblsummaOrder, font)));
                }
            }
            pdfDoc.Add(table);
            pdfDoc.Close();
            Response.End();

        }
