Hi @larryly 

Here is a great post done by @gmichaud showing how to leverage the pop up notes in the logic.

Thanks. @Fernando Amadoz . I saw that and just not good at C#. I can’t find right parameters to fit to the function. He use PopupNoteManager in FieldVerifying with pxcache and event as parameters. It’s different with my case. 

Are you trying to add a popup before the printing action is done(that can interrupt it) or just and informational popup that displays after?

@markusray17 I want to popup the message before open the report. I saw ppowell's question and use different way to popup the message. It works well for me.  Thanks.

Yeah that was going to be what I would suggest.

You could also optionally add the ability to cancel the action by using MessageButtons.OKCancel and wrapping it in an if statement. And you may want to check adapter.ExternalCall in case it is being called internally(processing screen, API, etc.).
