Compiled field in a Pdf not visible

[Andrea De Luca]

Hi, I have a file with compiled fields. The fields are visible in any standalone pdf viewer, but not in your pdfviewer.
Is there any option to view and print the entire document?

I've enclosed a file with this problem.

Thank you so much

Hi Andrea De Luca,

Thank you for contacting us and for sharing the document.

To investigate the issue where compiled form fields are not visible in PDF Viewer, could you please provide us with a few additional details?

• Which Syncfusion PDF Viewer platform are you using?
• Product version of the PDF Viewer control you are currently using?
• A simple replication sample (if possible) that demonstrates the issue with your file.
• Any specific steps you follow before the issue appears.

These details will help us analyze the scenario accurately and provide the appropriate solution.

We look forward to your response.

Regards,

Hi, the plartform is WinUI. the version of pdf viewer is 32.2462.3.0

Simply I load the pdf, the file is visible, but the fields are hidden.

Hi Andrea,

Thank you for sharing the details.

We would like to clarify that Syncfusion does not provide a direct PDF Viewer control for the WinUI platform. The PDF Viewer can be used in a WinUI application only by embedding the .NET MAUI PDF Viewer into a native WinUI app, as described in the following knowledge base article:
Integrate .NET MAUI PDF Viewer in native WinUI app | Syncfusion

We tested the shared PDF document using the integrated .NET MAUI PDF Viewer embedded in a WinUI application, and in our testing, all form fields are rendered correctly without any issues.

Regarding the version you mentioned (32.2462.3.0), this version is not available on NuGet.org for the .NET MAUI PDF Viewer. Could you please confirm:

• Whether you are using the .NET MAUI PDF Viewer as described in the above KB article, and
• In which platform NuGet the mentioned version (32.2462.3.0) available

This information will help us better understand your setup and assist you further.

Looking forward to your clarification.

Regards,

Bharathi S

Yes, it was my mistake. It' s a Windows forms application

Hi Andrea De Luca,

In WinForms PdfViewer, we currently do not support  viewing Form fields values in PDF documents. However, we can achieve this in WPF PdfViewer, which has support viewing Form fields values in the document. As a workaround we can use WPF PdfViewer  control in WinForms application via hosted element. We have shared the UG link for your reference that guide you to host WPF pdfviewer in WinForms:

UG link for hosted sample: Enhance WinForms PdfViewer with WPF Features | Syncfusion®

Please check it and let us know if you have any concerns or require further assistance.
