    <p>I have a button in ASP.NET that when its clicked it gets a rdlc file and generates a PDF file with a print dialog screen. What I want is to print it directly without the print dialog, I know it can be done with Javascript but I dont have any idea how to do this in javascript.</p> <pre><code> &lt;iframe id="frmPrint" name="IframeName" width="500" height="200" runat="server" style="display: none"&gt;&lt;/iframe&gt; </code></pre> <p>Code in aspx.cs</p> <pre><code>public void PrintTicket() { string[] streamids; string reportType = "PDF"; string mimeType; string encoding; //string fileNameExtension = "pdf"; string extension; LocalReport report = new LocalReport(); //Displays ticket letter and number in ticket report.ReportPath = "PrintTicket.rdlc"; ReportParameter ticket_parameter = new ReportParameter(); ticket_parameter.Name = "Ticket"; ticket_parameter.Values.Add(TicketNo); report.SetParameters(new ReportParameter[] { ticket_parameter }); //Displays date and time in ticket ReportParameter date = new ReportParameter(); date.Name = "Date_Time"; date.Values.Add(System.DateTime.Now.ToString()); report.SetParameters(new ReportParameter[] { date }); //Displays branch location in ticket ReportParameter location_parameter = new ReportParameter(); location_parameter.Name = "Location"; location_parameter.Values.Add(location); report.SetParameters(new ReportParameter[] { location_parameter }); string deviceInfo = "&lt;DeviceInfo&gt;" + " &lt;OutputFormat&gt;EMF&lt;/OutputFormat&gt;" + " &lt;PageWidth&gt;8.5in&lt;/PageWidth&gt;" + " &lt;PageHeight&gt;11in&lt;/PageHeight&gt;" + " &lt;MarginTop&gt;0.10in&lt;/MarginTop&gt;" + " &lt;MarginLeft&gt;0.02in&lt;/MarginLeft&gt;" + " &lt;MarginRight&gt;0.25in&lt;/MarginRight&gt;" + " &lt;MarginBottom&gt;0.15in&lt;/MarginBottom&gt;" + "&lt;/DeviceInfo&gt;"; Warning[] warnings; byte[] bytes = report.Render("PDF", deviceInfo, out mimeType, out encoding, out extension, out streamids, out warnings); FileStream fs = new FileStream(HttpContext.Current.Server.MapPath("output2.pdf"), FileMode.Create); fs.Write(bytes, 0, bytes.Length); fs.Close(); //Open existing PDF Document document = new Document(PageSize.LETTER); PdfReader reader = new PdfReader(HttpContext.Current.Server.MapPath("output2.pdf")); //Getting a instance of new PDF writer PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath("Print.pdf"), FileMode.Create)); document.Open(); PdfContentByte cb = writer.DirectContent; int i = 0; int p = 0; int n = reader.NumberOfPages; iTextSharp.text.Rectangle psize = reader.GetPageSize(1); float width = psize.Width; float height = psize.Height; //Add Page to new document while (i &lt; n) { document.NewPage(); p++; i++; PdfImportedPage page1 = writer.GetImportedPage(reader, i); cb.AddTemplate(page1, 0, 0); } //Attach javascript to the document PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer); writer.AddJavaScript(jAction); document.Close(); //Attach pdf to the iframe frmPrint.Attributes["src"] = "Print.pdf"; } </code></pre>

    1. COYou mean the system print dialog box? That will always be there using Javascript. Could you imagine if anyone could print anything without confirmation?

    3. COI understand the requirement you have. It isn't going to happen using Javascript. You would need direct access to the printer port on the machine you want to print from. I only see that happening from a desktop application that you've written and installed on the machine you want to print from.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
