Change Widget Annotation Options

A widget annotation contains a form field’s appearance and display properties. One field can be related to multiple widget annotations. Use the Widgets property to get the widget settings of each radio button in the group.

Note

The FontName, FontSize, FontBold and FontItalic properties do not affect the radio button appearance.

The code sample below changes the radio button style and color settings:

C#

using (PdfDocumentProcessor pdfDocumentProcessor = new PdfDocumentProcessor())
{
    pdfDocumentProcessor.LoadDocument("Documents//FormDemo.pdf");

    PdfDocumentFacade documentFacade = pdfDocumentProcessor.DocumentFacade;
    PdfAcroFormFacade acroForm = documentFacade.AcroForm;
    PdfRadioGroupFormFieldFacade genderField = acroForm.GetRadioGroupFormField("Gender");

    //Change marker style for all radio buttons:
    foreach (PdfRadioButtonWidgetFacade widget in genderField.Widgets)
    {
        widget.ButtonStyle = PdfAcroFormButtonStyle.Square;
        widget.BorderWidth = 1;
        widget.BackgroundColor = new PdfRGBColor(0.81, 0.81, 0.81);
