How can I open the generated PDF document directly into the browser window instead of displaying the Open or Save dialog in the browser

Syncfusion Essential® PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can create a PDF document and open it directly in the browser window.

Steps to open the generated PDF document directly in the browser window:

1. Create a new ASP.NET MVC application project.

2. Install the Syncfusion.Pdf.AspNet.MVC NuGet package as a reference to your .NET Framework application from NuGet.org.

3. A default controller with a name HomeController.cs gets added on the created ASP.NET MVC project. Include the following namespaces in that HomeController.cs.

C#

using Syncfusion.Pdf;
using System.Drawing;
using Syncfusion.Pdf.Graphics;

VB.NET

Imports Syncfusion.Pdf
Imports System.Drawing
Imports Syncfusion.Pdf.Graphics

4. Add a new action method named CreateDocument in the HomeController.cs and include the following code snippet to create a PDF file and open it in a browser.

C#

// Create an instance of PdfDocument.
using (PdfDocument document = new PdfDocument())
{
    // Add a page to the document
    PdfPage page = document.Pages.Add();
 
    // Create the PDF graphics for the page
    PdfGraphics graphics = page.Graphics;
 
    // Set the standard font
    PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);
 
    // Draw the text
    graphics.DrawString("Hello World!!!", font, PdfBrushes.Black, new PointF(0, 0));
 
    // Open the document in the browser after saving it
    document.Save("Output.pdf", HttpContext.ApplicationInstance.Response, HttpReadType.Open);
}

VB.NET

'Create an instance of PDF document 
Using document As PdfDocument = New PdfDocument()
 
    'Add a page to the document 
    Dim page As PdfPage = document.Pages.Add()
 
    'Create the graphics for the page 
    Dim graphics As PdfGraphics = page.Graphics
 
    'Set the standard font 
    Dim font As PdfFont = New PdfStandardFont(PdfFontFamily.Helvetica, 20)
 
    'Draw the text 
    graphics.DrawString("Hello World!!!", font, PdfBrushes.Black, New PointF(0, 0))
 
    'Open the document in the browser after saving it
    document.Save("Output.pdf", HttpContext.ApplicationInstance.Response, HttpReadType.Open)
End Using

A complete working sample can be download from CreatePDFSample.zip.
