Power Fx Confirm: Safer Canvas Apps

Key insights

• Confirm function: A built-in Power Fx dialog that shows a native confirmation prompt and returns a Boolean (true if the user confirms, false if they cancel).
  Use it directly in formulas like If(Confirm("Are you sure?"), Action()) to run actions only after user confirmation.
• OptionsRecord and customization: You can pass options such as Title, Subtitle, ConfirmButton, and CancelButton to change dialog text and labels.
  Styling control is limited and the dialog supports only the standard confirm and cancel buttons.
• Benefits: Confirm replaces manual popups and visibility toggles, reducing maintenance and keeping logic compact.
  It gives a consistent, native user experience and makes formulas easier to read and maintain.
• Requirements and availability: Microsoft documents Confirm for model-driven app commanding, and the community reports it works in canvas apps when modern controls and themes are enabled.
  Behavior may vary by runtime, so test in your target app and platform.
• Limitations: The dialog supports only two buttons and offers limited styling options.
  Complex interactions, more buttons, or custom layouts still require handcrafted popups or components.
• Practical use cases: Common patterns include confirming record deletes with a follow-up notification, or prompting before sending an email with a blank subject.
  Wrap Confirm in If(...) to run deletions, submissions, or navigation only when users confirm, and choose a custom popup when you need richer UI or inputs.
