Hi balj,

If your requirement wants to detect the Javascript action in the PDF document, we can detect the JavaScript actions by using Action property from PdfLoadedDocument instance. We have attached the sample for your reference, please try the sample on your end and let us know satisfy your requirement or not. 

 

Please find the code snippet, 

//Load a PDF document. 

 

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(stream); 

 

//Check and Change the javascript action in a pdf document. 

 

if (loadedDocument.Actions != null) 

{ 

    loadedDocument.Actions.AfterOpen = new PdfJavaScriptAction("app.alert(\"Modified Script!\")"); 

} 

 

MemoryStream stream1 = new MemoryStream(); 

 

loadedDocument.Save(stream1);
