  If you want to use OnBeforePrint event in Delphi's code - use TfrxReport.OnBeforePrint event

  You can assign TfrxMasterData.OnBeforePrint with script event only

  Yes, but masterdata1onbeforeprint event should be placed in script code, not in Delphi code

  When building reports from delphi code you can create events for the internal report script and connect them to objects.
  here is a sample.
