How to set custom PDF information


I am trying to set custom PDF information that is shown in AdobeReader in this position


I tried to set this with 

pdfViewer.LoadedDocument.DocumentInformation.CustomMetadata.Add("trallala", "hopsasa")

But the metadata is not added. Trying to set Author or Title of the document works fine.

What I am doing wrong?

Thank you, Marco

Please use the below code snippet to add metadata to the existing pdf document:

pdfViewer.LoadedDocument.DocumentInformation.CustomMetadata["trallala"] = "hopsasa";

Please try this in your end and let us know the result.
