I have tried to make a Button component that sends a paramater to another screen through the Navigate function.

This command works fine when entered in OnSelect directly on a button on a screen (not via component):

Navigate(Screen2,ScreenTransition.Fade, {sendparam: "hello"})
 
If I understood correctly, it is not possible to use a context variable in Navigate in a Component. 
Have asked both Chatgpt, Copilot, Grok and Deepseek - but no solution.
 
Anyone done this ?

And can share an example of a working component ?

Thanks a lot in advance !

You're trying to pass a parameter from a Power Apps component to another screen using the Navigate function, and you're encountering issues when doing this from within a component. Let’s break this down and clarify what works—and what doesn’t.

What Works (and Why)

When you use Navigate(Screen2, ScreenTransition.Fade, {sendparam: "hello"}) directly on a screen control (like a button), it works because the Navigate function supports passing context variables to the target screen. These variables are scoped to the screen and are available as soon as the screen loads.

This is confirmed by Microsoft Learn documentation and community examples .

Why It Fails in a Component

Power Apps components are isolated from the app’s screen context. This means:

You cannot directly use Navigate(..., ..., {param}) inside a component to pass parameters to a screen.
Components do not have access to screen context variables or the ability to define them directly.

Workaround: Use Custom Properties

To pass parameters from a component to a screen, you can use custom output properties in the component. Here’s how:

Create an Output Property in your component (e.g., SelectedValue).
Set the property based on user interaction inside the component (e.g., when a button is clicked).
Use the component in a screen, and bind the output property to a variable or directly in the Navigate call.

Example:

// OnSelect of a button outside the component

Navigate(Screen2, ScreenTransition.Fade, { sendparam: MyComponent.SelectedValue })
