How to create a PDF file in ASP.NET Web Forms PDF?
PDF (Portable Document Format) is the file format used to display a document with same formatting, independent of application software, hardware, and operating system. 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 in ASP.NET Web Forms.
Steps to create PDF programmatically:

- Install the Syncfusion.Pdf.AspNet NuGet package as reference to your .NET Framework applications from NuGet.org.
- Add a new Web Form in ASP .NET project. Right-click on the project and select Add > New Item and add a Web Form from the list. Name it as MainPage.
- Add a new button in the MainPage.aspx as follows.
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Button ID="Button1" runat="server" Text="Create Document" OnClick="OnButtonClicked" /> </div> </form> </body> </html>
- Include the following namespaces in your MainPage.aspx.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics; using System.Drawing;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics Imports System.Drawing
- Include the following code snippet in the click event of the button in MainPage.aspx.cs to create the PDF file and download it.
C#
using (PdfDocument document = new PdfDocument())
{
//Add a page to the document
PdfPage page = document.Pages.Add();
//Create 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 browser after saving it
document.Save("Output.pdf", HttpContext.Current.Response, HttpReadType.Open);
}
VB.NET
'Create an instance of PdfDocument.
Using document As PdfDocument = New PdfDocument()
