PowerApps Go back to previous screen


The Back function in Power Apps is used to navigate back to the previous screen in your app. This is particularly useful for creating user-friendly navigation.

PowerApps – Back() Syntax


Back([Transition])

- Here, Transition property is optional.

Note:

  • Back() function takes you to the exactly previous screen (the latest screen that you opened).
  • Back() function will return False if you are on the starting screen of the app and haven’t navigated to any other page since opening the app.
  • You can optionally use Navigate() function where you need to specify the screen where you want to go.
  • You can’t set context variable in Back() function unlike Navigate() function.

Simple Back Navigation in canvas app

  • You have 2 screens.
    • Screen1 (Home screen) and Screen2.
    • On Screen 2, put a button and in OnSelect() property of the button you can specify Back() function.

When the user clicks this button, they will be taken back to Screen1.

Consider an app with a more complex navigation structure, where users can navigate to multiple screens from various points. Adding a consistent back button on each screen improves user experience.

  1. Set up your screens:
    • HomeScreen
    • DetailsScreen
    • SettingsScreen
  2. Add a Back Button to DetailsScreen and SettingsScreen:
    • Insert a Button control on DetailsScreen.
    • Set its Text property to "Back".
    • Set its OnSelect property to:

Back()

    • Repeat the same steps for SettingsScreen.

This setup allows users to navigate back to the previous screen they visited, whether they came from HomeScreen, DetailsScreen, or SettingsScreen.
