Hi,
there are some callback Methods like OnAfterValueCnageCallback(IntPtr field).
How handle this in C#. Have I add this Method to Form?

Regards Peter

You should subscribe to the corresponding events of the PdfForm class instead of using a low-level api.

Code:
var doc = PdfDocument.Load("234234", new PdfForms());
doc.FormFill.AfterValueChange+= ...


or

Code:
pdfViewer1.FillForms.AfterValueChange+= ...
