Inside a ScrollBox I create in runtime some panels and inside each panel I create a frame with the panel as Parent.

Inside the frame I have a button that should Destroy the frame and the Panel.

How can I destroy the panel and the frame from that button?

Post a message to allocated invisible window and when that window receives it, remove that panel from the scroll box. – Victoria Sep 05 '17 at 09:21
Isn't the Release method designed for this? – David Heffernan Sep 05 '17 at 12:26

@DavidHeffernan Release is for forms, specifically TCustomFrom descendants. But the similar principle can be implemented for any control. – Dalija Prasnikar Sep 05 '17 at 13:20
Sorry, I thought Release was available for a win control. – David Heffernan Sep 05 '17 at 13:21
@DavidHeffernan Unfortunately, it is not. But it would make every sense to be there, too. – Dalija Prasnikar Sep 05 '17 at 13:49
Look at this [question](https://stackoverflow.com/questions/44487294/deleting-an-fmxobject-inside-its-event-handler) it has what you want. You need to create a new component though. – Nasreddine Galfout Sep 05 '17 at 19:10
@DavidHeffernan in the link above I used release to free the component (`TGroupBox`). second code the last 3 lines – Nasreddine Galfout Sep 05 '17 at 19:13

Only FMX objects has `Release` method: https://stackoverflow.com/questions/31785692/how-to-free-a-control-in-a-own-event – kobik Sep 07 '17 at 06:28
