The Syncfusion® .NET PDF library is used to create, read, and edit PDF documents. This library also offers functionality to merge, split, stamp, work with forms, and secure PDF files.

To include the .NET PDF library into your ASP.NET Web application, please refer to the NuGet Package Required or Assemblies Required documentation.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, you also have to add the Syncfusion.Licensing assembly reference and include a license key in your projects. Please refer to this link to learn about registering the Syncfusion® license key in your application to use our components.

Step 4: Add a new Web Form in the ASP.NET project. Right-click the project, select Add > New Item, and add a Web Form from the list. Name it MainPage.

Step 5: 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>

Step 6: Include the following namespaces in your MainPage.aspx.cs file.

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

Step 7: Include the following code example in the click event of the button in MainPage.aspx.cs to generate a PDF document using the PdfDocument class. Then use the DrawString method of the PdfGraphics object to draw text on the PDF page.

//Create a new PDF document. 
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.Save);
}
