ASP.Net: Export to PDF and open with save file dialog.

In last sample of my exporting sample series, I will demonstrate how to export data to PDF file in C#, ASP.Net. To export data in PDF file I’ll use iTextsharp library, which is included in source code project. For this example I’ll use same “GetData” method (to get the data for exporting) which we had used in Export to Excel example, you can use your own method to get data, if any.

/// <summary>
/// Export to Pdf file.
/// </summary>
public static void ExportPdfFile()
{
    //Create MemoryStream Object.
    var stream = new MemoryStream();

    //New Document with Page Size and Margins.
    var doc = new Document(PageSize.LETTER, 50f, 50f, 40f, 40f);

    // PdfWriter Object
    var writer = PdfWriter.GetInstance(doc, stream);
    writer.SetFullCompression();

    //Open document.
    doc.Open();

    //Font Factory to set font type, size and style.
    var style = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 14f, Font.BOLD);

    //Add header.
    doc.Add(new Paragraph("Export PDF Sample", style)
        {
            SpacingAfter = 10,
            Alignment = 3
        });

    //New PdfPTable.
    var table = new PdfPTable(4) { WidthPercentage = 100 };

    // Set columns widths
    int[] widths = { 25, 25, 25, 25 };
    table.SetWidths(widths);

    style = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 11f, Font.BOLD);

    table.AddCell(new PdfPCell(new Phrase("First Name", style)));
    table.AddCell(new PdfPCell(new Phrase("Last Name", style)));
    table.AddCell(new PdfPCell(new Phrase("Email Address", style)));
    table.AddCell(new PdfPCell(new Phrase("City", style)));

    style = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 11f, Font.NORMAL);

    //Get Records.
    var records = GetData();

    foreach (var record in records)
    {
        table.AddCell(new PdfPCell(new Phrase(record.FirstName, style)));
        table.AddCell(new PdfPCell(new Phrase(record.LastName, style)));
        table.AddCell(new PdfPCell(new Phrase(record.Email, style)));
        table.AddCell(new PdfPCell(new Phrase(record.City, style)));
    }

    //Add table to document.
    doc.Add(table);

    //close document
    doc.Close();

    //convert stream to byte array.
    var byteArray = stream.ToArray();
    stream.Flush();

    //close stream
    stream.Close();

    if (byteArray != null)
    {
        //Write and download file.
        var response = HttpContext.Current.Response;
        response.Clear();
        response.AddHeader("Content-Disposition"
            , "attachment; filename=Test_Data.pdf");
        response.AddHeader("Content-Length", byteArray.Length.ToString());
        response.ContentType = "application/pdf";
        response.BinaryWrite(byteArray);
        response.End();
    }
}

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI.
Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress).
//Created new Workbook var hwb = new NPOI.HSSF.UserModel.HSSFWorkbook(); //Create worksheet with name. var sheet = hwb.CreateSheet("new sheet"); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue("This is Merged cell"); cell.CellStyle.WrapText = true; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra);
Hope this solution helps you J

Read and parse a CSV file into an array of rows and columns in C#

The following PopulateCsvIntoArraymethod used to read the CSV file into a two-dimensional array of strings.
I have included explanation of method lines, wherever needed. ///<summary> /// Populate the CSV file into an array, /// We assume that every line has the same number of fields and there may be blank lines. ///</summary> ///<returns></returns> privatestring[,] PopulateCsvIntoArray() { // Get path of CSV file. var path = Server.MapPath("~/Folder_Name/testfile.csv"); // Get the file's text using ReadAllText method. string fileData = System.IO.File.ReadAllText(path);
// Split CSV data into lines.     fileData = fileData.Replace('\n', '\r'); string[] lines = fileData.Split(newchar[] { '\r' }, StringSplitOptions.RemoveEmptyEntries);
// Get rows and columns counts. int totalRows = lines.Length;

Calculate Sum and average of two or more Textbox values using JQuery

We can calculate sum and average of values entered in textboxes with the help of small piece of jQuery code.
First of all let’s create a HTML form where we’ll ask user to enter marks in each subject, under body section add following HTML:
<tableclass="demo-table"> <trclass="label"> <tdcolspan="2">Please enter marks(0-99):</td> </tr> <tr> <td>English</td> <td> <inputtype="text"class="txtMarks"name="txtMarks"
