Back and Navigate functions in Power Apps

Most apps contain multiple screens. Use the Back and Navigate function to change which screen is displayed. For example, set the OnSelect property of a button to a formula that includes a Navigate function if you want to show a different screen when a user selects that button. In that formula, you can specify a visual transition, such as Fade, to control how one screen changes to another.

Back and Navigate change only which screen is displayed. Screens that aren't currently displayed continue to operate behind the scenes. You can build formulas that refer to properties of controls on other screens. For example, a user can change the value of a slider on one screen, navigate to a different screen that uses that value in a formula, and determine how it affects what happens in the new screen. The user can then navigate back to the original screen and confirm that the slider has kept its value.

Context variables are also preserved when a user navigates between screens. You can use Navigate to set one or more context variables for the screen that the formula will display, which is the only way to set a context variable from outside the screen. You can use this approach to pass parameters to a screen. If you've used another programming tool, this approach is similar to passing parameters to procedures.

You can use either function only within a behavior formula.


In the first argument, specify the name of the screen to display.

In the second argument, specify how the old screen changes to the new screen:


The new screen slides into view, moving right to left, to cover the current screen.


The new screen slides into view, moving left to right, to cover the current screen.
