Find Page Number of Form Fields

[rja]

I'm able to get a list of fields on a form. But I would like to be able to determine which page each of those fields are on. Is there a way to get that information?

Alternatively, I'd be ok with just getting all the fields on a given page. That's pretty much the same thing for me.

thanks in advance!

Hi,

Thanks for your inquiry.
Spire.PDF supports to find the page the field is on at present. Please try to use the method field.Page() to get the page. Here is sample code for your reference:

Code: Select all

            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(FilePath + "FormField.pdf");
            PdfFormWidget formWidget = doc.Form as PdfFormWidget;           
            for (int i = 0; i < formWidget.FieldsWidget.List.Count; i++)
            {
                PdfField field = formWidget.FieldsWidget.List[i] as PdfField;
                PdfPageBase page = field.Page;
             ...
             }

If there is any question, welcome to get it back to us.

Thanks for the reply. I don't think there's a Page method, just the Page property, which returns a PdfPageBase object. However I don't believe that the PdfPageBase has a page number property (I apologize if that wasn't clear in my inquiry). Is it possible to get the form fields that are only on page 1 of the PDF, for example?

Hi,

Thanks for your reply.
Here is sample code for your reference:

Code: Select all

            PdfDocument pdf = new PdfDocument(FilePath + "sample.pdf");
            PdfFormWidget widget = pdf.Form as PdfFormWidget;
            Dictionary<int, List<PdfField>> allXOB = new Dictionary<int, List<PdfField>>();
            for (int i = 0; i < pdf.Pages.Count; i++)
            {
                allXOB.Add(i, new List<PdfField>());
            }
            int pageCount = allXOB.Count;
            if (widget != null)
            {
                for (int i = 0; i < widget.FieldsWidget.Count; i++)
                {
                    PdfField field = widget.FieldsWidget[i];
                    PdfPageBase page = field.Page;
                    for (int j = 0; j < pageCount; j++)
                    {
                        if (pdf.Pages[j].Equals(page))
                        {
                            allXOB[j].Add(field);
                            break;
                        }
                    }
                }
            }
