Merging PDFs with Acro Fields

I need to merge two PDFs together. One will be an overlay file containing artwork and some Acro fields, and the other will contain invoice data.

I am using the following code for testing:

        private void MergePDF()
        {
            string dataPDF = @"C:\Data.Pdf";
            string overlayPDF = @"C:\Overlay.Pdf";
           
            var overlayPage = new ImportedPageArea(overlayPDF, 1, 0, 0) { Contents = { ClipLeft = 0, ClipTop = 0, ClipRight = 0, ClipBottom = 0 }};            
            var dataPage = new ImportedPageArea(dataPDF, 1, 0, 0) { Contents = { ClipLeft = 0, ClipTop = 0, ClipRight = 0, ClipBottom = 0 }};

            var page = new ceTe.DynamicPDF.Page(PageSize.A4, PageOrientation.Portrait) { Dimensions = { LeftMargin = 0, TopMargin = 0 }};
            page.Elements.Add(overlayPage);
            page.Elements.Add(dataPage);

            var document = new ceTe.DynamicPDF.Document();
            document.Pages.Add(page);
            document.Draw(@"C:\Result.pdf");
        }

The Acro fields not appearing on the merged Pdf.

Can anyone help me with this please?

Hello,

You are seeing this behavior because of using ImportedPageArea to import the data from a PDF that contains acro fields. The ImportePageArea is not capable of importing acro fields. You have to use ImportePage object and below is the code sample for it. 

            string dataPDF = @"C:\Data.Pdf";
            string overlayPDF = @"C:\Overlay.Pdf";
            ImportedPage page = new ImportedPage(overlayPDF, 1);
           var dataPage = new ImportedPageArea(dataPDF, 1, 0, 0) { Contents = { ClipLeft = 0, ClipTop = 0, ClipRight = 0, ClipBottom = 0 } };
            page.Elements.Add(dataPage);
            var document = new ceTe.DynamicPDF.Document();
            document.Pages.Add(page);
            document.Draw(@"C:\Result.pdf");

Thanks,

Thank you.  That is working now.
