Open PDF in new tab and have .pdf extension


We have implemented Aspose.Pdf in one of our functionality to update PDF add some text and showing to user. Here we need a function/method that will ;
1. After writing the text, load same PDF in same browser's new tab(Not in new window)
2. PDF opened in browser needs to show .pdf page extension in url rather than .aspx page

For your reference we have used below code,

//open document
Document pdfDocument = new Document(sr.BaseStream);

Aspose.Pdf.Page pdfPage = null;

//accept for a particular page
pdfPage = (Aspose.Pdf.Page)pdfDocument.Pages[PdfPageNumber];

//create text fragment
TextFragment textFragment = new TextFragment(textToWrite);

//set corordinate
textFragment.Position = new Position(PrintPdfXCoordinate, PrintPdfYCoordinate);
//set text properties
textFragment.TextState.FontSize = PrintPdfCouponCodeFontSize;
textFragment.TextState.BackgroundColor = System.Drawing.Color.LightBlue;
textFragment.TextState.ForegroundColor = System.Drawing.Color.Black;
textFragment.TextState.FontStyle = FontStyles.Bold;

// create TextBuilder object
TextBuilder textBuilder = new TextBuilder(pdfPage);

// append the text fragment to the PDF page

//generate new Pdf file output stream.
MemoryStream outStream = new MemoryStream();

// specify the duration of time before a page,cached on a browser expires
HttpContext.Current.Response.Expires = 0;

// Specify the property to buffer the output page
HttpContext.Current.Response.Buffer = true;

// Erase any buffered HTML output

//Add a new HTML header and value to the Response sent to the client
HttpContext.Current.Response.AddHeader("content-disposition", "inline; filename=output.pdf");

// Specify the HTTP content type for Response as Pdf
HttpContext.Current.Response.ContentType = "application/pdf";

// Write specified information of current HTTP output to Byte array

// close the output stream

Can you please let us know solution for above mentioned issue ASAP ?


Hi Kishan,

Thanks for contacting support.

We are looking into the details of this requirement and will get back to you soon. Please be patient and spare us little time.

Hi Kishan,

Thanks for your patience.

I have tested this scenario and when I have executed the earlier shared code snippet, the resultant file is being displayed in a new tab of my default web browser. In case the browser is not already open, it will be launched to display the PDF document in first tab. In case I am not able to understand your requirement, please share some further details.
