Tab Control vs. Navigation Screens in Power Apps: When to Use What

When you're building an app in Power Apps, you often need to show different sections of content. There are two popular ways to do this:

Tab Controls: switch between sections on the same screen
Navigation Screens: move between different screens

Let’s break down what each one is, when to use them, and how to implement them with easy-to-understand examples.

What is a Tab Control?

A Tab Control is like the tabs you see in a web browser or settings page. You stay on the same screen, but the content changes based on which tab you click.

Why Use It?

Keeps everything on one screen
Makes the app feel faster
Great for forms, dashboards, or grouped settings

How to Build It?

You can create tabs using buttons and a variable to control which content is visible.

Example

Let’s say you have 3 tabs: Overview, Details, and Settings.

1. Add 3 buttons at the top of your screen.

2. Set their OnSelect properties like this:

// Overview Button
UpdateContext({selectedTab: "Overview"})

// Details Button
UpdateContext({selectedTab: "Details"})

// Settings Button
UpdateContext({selectedTab: "Settings"})

3. Now, for each content section (like a container or group), set the Visible property:

// Overview Section
selectedTab = "Overview"

// Details Section
selectedTab = "Details"

// Settings Section
selectedTab = "Settings"

What is a Navigation Screen?

Navigation Screens involve moving between separate screens using the Navigate() function. Each screen can have its own layout, logic, and data.

Why Use It?

Better for large or complex apps
Each screen can have its own logic and data
Easier to manage when things get big

How to Build It?

Let’s say you have 3 screens: HomeScreen, ReportScreen, and SettingsScreen.

Example

Add buttons and set their OnSelect properties like this:

// Go to Reports
Navigate(ReportScreen, ScreenTransition.Fade)

// Go to Settings
Navigate(SettingsScreen, ScreenTransition.Cover)

Each screen can have its own layout, controls, and data sources.

Tab Control vs. Navigation Screens

Feature	Tab Control	Navigation Screens
Where it happens	Same screen	Different screens
Speed	Faster (no screen load)	Slightly slower
Best for	Forms, dashboards	Large apps, modules
Complexity	Simple apps	Complex apps
Data sharing	Easy (same screen)	Needs passing variables
Maintenance	Harder if too many tabs	Easier to organize

When Should You Use Each?

Use Tab Control when

You want a clean, fast UI
The content is related (like steps in a form)
You want to avoid too many screens

Use Navigation Screens when

Each section is big or has different logic
You want to keep things modular
You’re building a multi-feature app

Conclusion

Both Tab Controls and Navigation Screens are essential tools in Power Apps. Choosing the right one depends on your app’s structure, complexity, and user experience goals. Often, the best apps use a hybrid approach, combining both for maximum flexibility.
