How to Create PDF Forms in C# Using IronPDF

In this tutorial, you'll learn how to create editable PDF forms in C# using IronPDF. Begin by installing IronPDF through the NuGet package manager. Once installed, navigate to the program CS file to set up your environment. A key step is to ensure your IronPDF license key is set, whether it’s a paid or trial version. The HTML of your form, which includes fields like first name, last name, address, and preferred travel type via radio buttons, acts as the blueprint for your PDF form. You'll instantiate the Chrome PDF renderer, which is responsible for converting the HTML into a PDF. It's crucial to configure the renderer to create PDF forms from HTML by setting the appropriate flag to true. This ensures the HTML form elements are correctly rendered into an interactive PDF format. By following these steps, you can efficiently create and manipulate PDF forms within your C# applications, enhancing functionality and user interaction.

Explanation of Key Steps in the Code:

1. License Key Setup: The LicenseKey constant should hold the license key provided when you purchase IronPDF. The IronPdf.License.LicenseKey must be set to allow you to use the library.
2. HTML Form Structure: A simple form in HTML is defined with text input fields and radio buttons to capture user details and preferences.
3. Chrome PDF Renderer Setup: ChromePdfRenderer is used to handle the conversion of the HTML content to a PDF format.
4. Enabling PDF Forms: By setting renderer.RenderingOptions.PdfFormsEnabled to true, the PDF will retain the form fields as interactive elements.
5. PDF Creation and Storage: The RenderHtmlAsPdf method is used to generate a PDF document from the HTML, which is then saved to a specified path.
