Power Fx function
Complete A–Z reference
App
Info and control for the running app.
What it does
The job: Every function, signal, and operator entry in the canvas-apps reference.
How to use App
Start from the task, not the alphabet. If you are shaping rows for a gallery, reach for App alongside the other data functions in its group; if you are saving, navigating, or changing state, use it on an event such as a button OnSelect rather than in a display property. When a formula misbehaves, check for a blank value where you expected text, then confirm the behavior against the examples in the Power Fx function reference hub.
