Setting borders for the rows range

Jan 18, 2011 at 1:45 PM

I need to export data into Excel, but need to use a template (.xls file) that has other content as well.

When I insert rows into the excel file (in between where i need to set the data that i'm exporting) and try to set the borders for the rows (cellstyle), I just don't see the borders for the rows that I set the style to, but instead entire generated excel has the cellstyle changed to the border that I'm setting. Following is my code.

 myPath = string.Concat(Server.MapPath("~"), myPath, "RFQ_Costed_BOM.xls");

            NPOI.HSSF.UserModel.HSSFWorkbook workbook = new NPOI.HSSF.UserModel.HSSFWorkbook();
            HSSFSheet worksheet;
            
            FileStream fs = new FileStream(myPath, FileMode.Open, FileAccess.Read);
            workbook = new HSSFWorkbook(fs, true);
            worksheet = (HSSFSheet)workbook.GetSheetAt(0);

         
            for (int j = iExcelRow; j < iExcelRow + iRows; j++)
            {
                HSSFRow row = (HSSFRow)worksheet.CreateRow(j);
                for (int l = 0; l < 12; l++)
                { 
                    HSSFCell cell =  (HSSFCell)row.CreateCell(l);
                    cell.CellStyle.BorderBottom = NPOI.SS.UserModel.CellBorderType.THIN;
                }
            
            }
Keen to know what might be going wrong.
