Example

How to: Add a Text Box Field to a PDF Document

The following code snippet adds a text field to a PDF document and binds it to a text widget:

C#

using DevExpress.Docs.Pdf;
using DevExpress.Drawing.Printing;
using System.Drawing;

namespace ConsoleApp1;

public class Program {
    public static async Task Main(string[] _) {
        using (PdfDocument pdfDocument = new()) {
            // Add an A4 page to the document.
            Page page = pdfDocument.Pages.Add(DXPaperKind.A4);

            TextFont textFont = new("SegoeUI", TextFontStyle.Regular);

            float y = 750;
            float step = 30;
            float textHeight = 14f;

            // Create a label for the text field.
            TextFragment loginLabel = new() {
                Text = "Login:",
                Location = new PointF(50, y - textHeight / 2),
                Font = textFont
            };
            page.Fragments.Add(loginLabel);

            // Create a text field and add it to the field collection.
            TextBoxField loginField = new("Login");
            pdfDocument.Fields.Add(loginField);

            // Bind the text field to a widget and place it on the page.
            RectangleF loginBounds = new(120, y - textHeight + 4, 220, textHeight);
            TextBoxWidgetAnnotation loginWidget = new(loginField, loginBounds);
            loginWidget.FontSize = 14;
            page.Annotations.Add(loginWidget);
            y -= step;

        }
    }
}
