Hi Manolo, 

 

On further analysis, we found that the input document has extended features enabled and its security is restricted to modify the PDF document. We also ensured the same behavior is Acrobat too and we do not remove any fields from this document, the form fields are unable to click/not accessible in viewer due to Extended features security restriction. However, we can able to allow to edit and fill the form fields by setting the necessary permission in the document. 

 

Please refer to the code below to overcome this behavior, 

 

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(pdfStream); 

 

            if(loadedDocument.IsExtendedFeatureEnabled) 

            loadedDocument.Security.Permissions =  Syncfusion.Pdf.Security.PdfPermissionsFlags.FillFields| Syncfusion.Pdf.Security.PdfPermissionsFlags.EditAnnotations 

                    | Syncfusion.Pdf.Security.PdfPermissionsFlags.EditContent; 

 

 

 

 

Please lets us know, you have any concerns about this.
