USING IRONPDF

.NET PDF Generator in 1 Click

Updated December 3, 2023

With an extensive C# library, we can convert ASP.NET to PDF and HTML to PDF, and have full control over reading PDF files in C#, editing PDFs programmatically, and manipulating documents with custom headers and footers. Using IronPDF, we can convert an ASP.NET page to a PDF document in just a single line of code. Here's how.

Step 1

1. Download IronPDF for C#

To get access to the full software library of C# PDF functionality, you can download IronPDF and use it free for development in your project and this tutorial.

There are two ways to download, whichever is easiest for you. Either install from a ZIP DLL Download or use the package via NuGet Install for IronPDF.

Install-Package IronPdf

2. PDF .NET Generator

Convert

Once you install IronPDF into your Visual Studio project, it provides a vast number of methods to automate with PDF on ASP.NET such as replacing texts and images in PDFs. You can even convert an ASP.NET webpage to PDF in just one line of code, as we've done below.

It provides a flexible and reliable framework for ASP.NET to develop a PDF using C#, which we know as developers is essential for our projects.

In the code below, we used a single click to generate a PDF from the whole ASP.NET webpage, thanks to the API method RenderThisPageAsPdf.

/**
ASP NET PDF Generator
anchor-pdf-net-generator
**/
using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

/**

using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

3. One-Click PDF Conversion

Here we have demonstrated an example of how to convert an ASPX Web Page to a PDF using an IronPDF function. As soon as you click on the button, the whole web page will be converted to a PDF. Without losing any quality, the whole webpage gets replicated into an editable document. It's as simple as that!
