Example Code
AddFormFieldsToNewDocument/Program.cs(vb)
C#using DevExpress.Pdf;
using System.Drawing;
namespace AddFormFieldsToNewDocument {
class Program {
static void Main(string[] args) {
using (PdfDocumentProcessor processor = new PdfDocumentProcessor()) {
// Create an empty document.
processor.CreateEmptyDocument("..\\..\\Result.pdf");
// Create graphics and draw form fields.
using (PdfGraphics graphics = processor.CreateGraphics()) {
DrawFormFields(graphics);
// Render a page with graphics.
processor.RenderNewPage(PdfPaperSize.Letter, graphics);
}
}
}
static void DrawFormFields(PdfGraphics graphics) {
// Create a text box field and specify its location on the page.
PdfGraphicsAcroFormTextBoxField textBox = new PdfGraphicsAcroFormTextBoxField("text box", new RectangleF(30, 10, 200, 30));
// Specify text box text, and appearance.
textBox.Text = "Text Box";
textBox.Appearance.FontSize = 12;
textBox.Appearance.BackgroundColor = Color.AliceBlue;
// Add the text box field to graphics.
graphics.AddFormField(textBox);
// Create a radio group field.
PdfGraphicsAcroFormRadioGroupField radioGroup = new PdfGraphicsAcroFormRadioGroupField("First Group");
// Add the first radio button to the group and specify its location using a RectangleF object.
radioGroup.AddButton("button1", new RectangleF(30, 60, 20, 20));
// Add the second radio button to the group.
radioGroup.AddButton("button2", new RectangleF(30, 90, 20, 20));
// Specify radio group selected index, and appearance.
radioGroup.SelectedIndex = 0;
radioGroup.Appearance.BorderAppearance = new PdfGraphicsAcroFormBorderAppearance() { Color = Color.Red, Width = 3 };
// Add the radio group field to graphics.
graphics.AddFormField(radioGroup);
}
}
