Hi, i working on export ¿Arabic grid view to pdf file, and after hundred of Experiences i finally managed to solve the issue, there are now only one remaining issue i am facing, i can not change the width of the columns, i tried to use

    table.setWidths(columnWidths);

  iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(GridView1.Columns.Count);

            table.RunDirection = PdfWriter.RUN_DIRECTION_LTR;
            BaseFont bf = BaseFont.CreateFont("c:\\\\windows\\\\fonts\\\\tahoma.ttf", BaseFont.IDENTITY_H, true);
            iTextSharp.text.Font f2 = new iTextSharp.text.Font(bf, 8, iTextSharp.text.Font.NORMAL);
                            
            for (int i = 0; i < noOfColumns; i++)
            {
                Phrase ph = null;
               
                if (GridView1.AutoGenerateColumns)
                {
                    ph = new Phrase(tbl.Columns[i].ColumnName, FontFactory.GetFont("Tahoma", 8, iTextSharp.text.Font.BOLD));
                }
                else
                {
                    ph = new Phrase(GridView1.Columns[i].HeaderText, FontFactory.GetFont("Tahoma", 8, iTextSharp.text.Font.BOLD));
                }
                PdfPCell clHeader = new PdfPCell(ph);
                clHeader.BackgroundColor = new Color(System.Drawing.ColorTranslator.FromHtml("#e9e9e9"));
                
                table.AddCell(clHeader);                
            }
            
            for (int i = 0; i <= GridView1.Rows.Count-1; i++)
            {
                    for (int j = 0; j <= GridView1.Columns.Count - 1; j++)
                    {
                        string cellText = Page.Server.HtmlDecode(GridView1.Rows[i].Cells[j].Text);
                        iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(100, cellText, f2));                       
                        table.AddCell(cell);
                        
                    }
            }

            
            PdfWriter.GetInstance(document, Page.Response.OutputStream);
            document.Open();
            document.SetMargins(0, 0, 0, 0);

            document.Add(table); // add the table

            document.Close();
            Page.Response.ContentType = "application/pdf";
            Page.Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
            Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Page.Response.Write(document);
            Page.Response.End();

Hi,

You shouldn't be giving the width's in Floats instead try giving with integers!

If you wish to give in percentages - http://stackoverflow.com/questions/1481139/itextsharp-table-width-100-of-page

Hope it helps u...
