iTextSharpを使用してグリッドビューを印刷するには

Question

asp.netでiTextSharpを使用してGridViewデータ（すべて）を印刷する方法は？私は完全なコードではなくヒントを必要とするだけです

Answer 1

からリッピングすることはこれで試してみてください：

protected void ExportToPDF(GridView gvReport, bool LandScape) 
{ 
    int noOfColumns = 0, noOfRows = 0; 
    DataTable tbl = null; 

    if (gvReport.AutoGenerateColumns) 
    { 
     tbl = gvReport.DataSource as DataTable; // Gets the DataSource of the GridView Control. 
     noOfColumns = tbl.Columns.Count; 
     noOfRows = tbl.Rows.Count; 
    } 
    else 
    { 
     noOfColumns = gvReport.Columns.Count; 
     noOfRows = gvReport.Rows.Count; 
    } 

    float HeaderTextSize = 8; 
    float ReportNameSize = 10; 
    float ReportTextSize = 8; 
    float ApplicationNameSize = 7; 

    // Creates a PDF document 

    Document document = null; 
    if (LandScape == true) 
    { 
     // Sets the document to A4 size and rotates it so that the  orientation of the page is Landscape. 
     document = new Document(PageSize.A4.Rotate(), 0, 0, 15, 5); 
    } 
    else 
    { 
     document = new Document(PageSize.A4, 0, 0, 15, 5); 
    } 

    // Creates a PdfPTable with column count of the table equal to no of columns of the gridview or gridview datasource. 
    iTextSharp.text.pdf.PdfPTable mainTable = new iTextSharp.text.pdf.PdfPTable(noOfColumns); 

    // Sets the first 4 rows of the table as the header rows which will be repeated in all the pages. 
    mainTable.HeaderRows = 4; 

    // Creates a PdfPTable with 2 columns to hold the header in the exported PDF. 
    iTextSharp.text.pdf.PdfPTable headerTable = new iTextSharp.text.pdf.PdfPTable(2); 

    // Creates a phrase to hold the application name at the left hand side of the header. 
    Phrase phApplicationName = new Phrase("Sample Application", FontFactory.GetFont("Arial", ApplicationNameSize, iTextSharp.text.Font.NORMAL)); 

    // Creates a PdfPCell which accepts a phrase as a parameter. 
    PdfPCell clApplicationName = new PdfPCell(phApplicationName); 
    // Sets the border of the cell to zero. 
    clApplicationName.Border = PdfPCell.NO_BORDER; 
    // Sets the Horizontal Alignment of the PdfPCell to left. 
    clApplicationName.HorizontalAlignment = Element.ALIGN_LEFT; 

    // Creates a phrase to show the current date at the right hand side of the header. 
    Phrase phDate = new Phrase(DateTime.Now.Date.ToString("dd/MM/yyyy"), FontFactory.GetFont("Arial", ApplicationNameSize, iTextSharp.text.Font.NORMAL)); 

    // Creates a PdfPCell which accepts the date phrase as a parameter. 
    PdfPCell clDate = new PdfPCell(phDate); 
    // Sets the Horizontal Alignment of the PdfPCell to right. 
    clDate.HorizontalAlignment = Element.ALIGN_RIGHT; 
    // Sets the border of the cell to zero. 
    clDate.Border = PdfPCell.NO_BORDER; 

    // Adds the cell which holds the application name to the headerTable. 
    headerTable.AddCell(clApplicationName); 
    // Adds the cell which holds the date to the headerTable. 
    headerTable.AddCell(clDate); 
    // Sets the border of the headerTable to zero. 
    headerTable.DefaultCell.Border = PdfPCell.NO_BORDER; 

    // Creates a PdfPCell that accepts the headerTable as a parameter and then adds that cell to the main PdfPTable. 
    PdfPCell cellHeader = new PdfPCell(headerTable); 
    cellHeader.Border = PdfPCell.NO_BORDER; 
    // Sets the column span of the header cell to noOfColumns. 
    cellHeader.Colspan = noOfColumns; 
    // Adds the above header cell to the table. 
    mainTable.AddCell(cellHeader); 

    // Creates a phrase which holds the file name. 
    Phrase phHeader = new Phrase("Sample Export", FontFactory.GetFont("Arial", ReportNameSize, iTextSharp.text.Font.BOLD)); 
    PdfPCell clHeader = new PdfPCell(phHeader); 
    clHeader.Colspan = noOfColumns; 
    clHeader.Border = PdfPCell.NO_BORDER; 
    clHeader.HorizontalAlignment = Element.ALIGN_CENTER; 
    mainTable.AddCell(clHeader); 

    // Creates a phrase for a new line. 
    Phrase phSpace = new Phrase("\n");

    clSpace.Colspan = noOfColumns; 
    mainTable.AddCell(clSpace); 

    // Sets the gridview column names as table headers. 
    for (int i = 0; i < noOfColumns; i++) 
    { 
     Phrase ph = null; 

     if (gvReport.AutoGenerateColumns) 
     { 
      ph = new Phrase(tbl.Columns[i].ColumnName, FontFactory.GetFont("Arial", HeaderTextSize, iTextSharp.text.Font.BOLD)); 
     } 
     else 
     { 
      ph = new Phrase(gvReport.Columns[i].HeaderText, FontFactory.GetFont("Arial", HeaderTextSize, iTextSharp.text.Font.BOLD));     
     } 

     mainTable.AddCell(ph); 
    } 

    // Reads the gridview rows and adds them to the mainTable 
    for (int rowNo = 0; rowNo < noOfRows; rowNo++) 
    { 
     for (int columnNo = 0; columnNo < noOfColumns; columnNo++) 
     { 
      if (gvReport.AutoGenerateColumns) 
      { 
       string s = gvReport.Rows[rowNo].Cells[columnNo].Text.Trim(); 
       Phrase ph = new Phrase(s, FontFactory.GetFont("Arial", ReportTextSize, iTextSharp.text.Font.NORMAL)); 
       mainTable.AddCell(ph); 
      } 
      else

       { 
        DataBoundLiteralControl lc = gvReport.Rows[rowNo].Cells[columnNo].Controls[0] as DataBoundLiteralControl;

        Phrase ph = new Phrase(s, FontFactory.GetFont("Arial", ReportTextSize, iTextSharp.text.Font.NORMAL));

      } 
     } 

     // Tells the mainTable to complete the row even if any cell is left incomplete. 
     mainTable.CompleteRow(); 
    } 

    // Gets the instance of the document created and writes it to the output stream of the Response object. 
    PdfWriter.GetInstance(document, Response.OutputStream);
