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 form field widget settings.

The code sample below changes the list box appearance:

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

    PdfDocumentFacade documentFacade = pdfDocumentProcessor.DocumentFacade;
    PdfAcroFormFacade acroForm = documentFacade.AcroForm;
    PdfListBoxFormFieldFacade listField = acroForm.GetListBoxFormField("List");

    PdfListBoxWidgetFacade listBoxWidget = listField.Widgets[0];
    listBoxWidget.BorderWidth = 1;
    listBoxWidget.BackgroundColor = new PdfRGBColor(0.81, 0.81, 0.81);
    listBoxWidget.BorderColor = new PdfRGBColor(0.47, 0.44, 0.67);
    listBoxWidget.FontColor = new PdfRGBColor(0.34, 0.25, 0.36);
}
