How can you add logic to the default "X" button in a Form title bar?

Hi there!

Unfortunately, it is not possible to add any logic to the default “X” button within a Form’s title bar. Here is a solution that may work for your project needs:

1. You can disable the Form title bar by navigating to Form Setup -> Sizing -> Sub-Dialog -> Hide Title Bar. By doing this, you could force the user to interact with a standard form button to exit the form and run some additional logic after.

The resulting Form after checking the Hide Title Bar option.

Note: The title bar within a Form will always appear while in the Debugger.

Hope this helps!
