PdfWidgetFacade Class

Contains basic widget annotation properties.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v21.2.Core.dll

Declaration

public abstract class PdfWidgetFacade

Remarks

A widget annotation contains a form field’s appearance and display properties. One field can be related to multiple widget annotations. Use the PdfFormFieldFacade.Widgets property to retrieve the form field widgets settings.

The code sample below retrieves all fields and changes their appearance:

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

    PdfDocumentFacade documentFacade = pdfDocumentProcessor.DocumentFacade;
    PdfAcroFormFacade acroForm = documentFacade.AcroForm;

    //Change all form fields' color settings:
    var fields = acroForm.GetFields();
    foreach (PdfFormFieldFacade field in fields)
    {
        ChangeFormFieldColor(field);
    }
}
  private static void ChangeFormFieldColor(PdfFormFieldFacade field)
  {
      foreach (PdfWidgetFacade pdfWidget in field)
      {
          //Change color and border settings
          //for all form fields:
          pdfWidget.BorderWidth = 1;
          pdfWidget.BackgroundColor = new PdfRGBColor(0.81, 0.81, 0.81);
          pdfWidget.BorderColor = new PdfRGBColor(0.47, 0.44, 0.67);
          pdfWidget.FontColor = new PdfRGBColor(0.34, 0.25, 0.36);

          //Change border style for text form fields:
          if (field.Type == PdfFormFieldType.Text)
          {
              pdfWidget.BorderStyle = PdfBorderStyle.Underline;
          }
      }
  }
