Outlook desktop renders blank Form Fields PDFs generated via Syncfusion version 15.43

Question

Hi,

We got a problem with PDF files preview in Outlook.

PDF files with form fields were generated via Syncfusion version 15.43 and appear to be BLANK (custom input not displaying) (Adobe reader is previewer)
However, the same files open nice in Adobe Reader directly.

Please let us know what can we do to fix it?

best regards,

alex

Hi Alex,As you can see from this article, Outlook doesn't have a built-in PDF previewer and if you
want to open PDF files, you may need Adobe Reader and then open the PDF file in preview mode. So,
In preview mode, we can’t able to edit the form fields. It’s not an issue, it’s
the behavior.Refer to the
following article for more details about outlook PdfViewer, https://answers.microsoft.com/en-us/outlook_com/forum/all/when-i-open-pdf-files-in-outlook-they-open-into/cf8cd53c-2365-488e-b078-8eba87607ff1Please let us know if
you have any concerns about this.Regards,Surya V

Hi Surya,

thanks for your reply.

Our problem is that we do not see values in the inputs for PDFs files generate via syncfusion in the Outlook previewer.

1) No, we don't want to edit PDFs from the outlook, but only view inputs values that were added to the PDF using

syncfusion

2) Already have Adobe Reader installed as a previewer for Outlook.

Should we change smth in the code or update the version?

Please confirm editable forms PDF files can be viewed properly in outlook?

Hi Alex,Thanks for the details. We recommend you disable the PdfForm
set appearance to overcome the reported issue. Because, After filling the form
fields in the PDF document, it may appear empty due to the absence of the
appearance dictionary. By setting false to the SetDefaultAppearance() method in
PdfForm class, you can create the appearance dictionary. By this, the text will
be visible in all PDF Viewers.Kindly refer the following code snippet to overcome the
reported issue,

//Load the PDF document
  PdfLoadedDocument loadedDocument = new
  PdfLoadedDocument(fileName);
   
  //Get the loaded form
  PdfLoadedForm loadedForm = loadedDocument.Form;
   
  //Set the default appearance
  loadedForm.SetDefaultAppearance(false);
   
  //Get the loaded form field
  PdfLoadedTextBoxField loadedTextBoxField =
  loadedForm.Fields[0] as PdfLoadedTextBoxField;
   
  loadedTextBoxField.Text = "Text";
   
  //Save the document
  loadedDocument.Save("Form.pdf");
  //Close the document
  loadedDocument.Close(true);
