Only show ConfirmExit per screen

[oappdev]

Happy Saturday!

What is the best approach to have the ConfirmExit work per screen? Is it possible ?

Example 

Screen1 Is the form where users enter information also where the ConfirmExit show prompt them

Screen2  Where ConfirmExit doesn't prompt them.

Thank you in advance

I think the simplest approach would be to put this code in the OnVisible property of each screen

Set(currentScreen, "Screen1")

Set(currentScreen, "Screen2")

Then use this code in the ConfirmExit property of the app to conditionally show the prompt based on the current screen.

Switch(
    currentScreen,
    "Screen1", true,
    "Screen2", false
)

The SWITCH function above can be modified to accommodate as many screens as you need.

That did the trick @mdevaney 😎 Going to push it to production on Monday

@mdevaney  solution can be improved by using App.ActiveScreen.Name

It SHOULD be possible to use that directly in the ConfirmExit formula (App.ActiveScreen.Name = "Screen1"), but annoyingly it gives the error:

"The control reference cannot be used in this property"

However, it can still be helpful to use to dynamically populate the variable, so you can create the formula once and copy/paste it to every OnVisible screen, and it will automatically update if you change a screen's name.

ConfirmExit is the same as yours, but in OnVisible for each screen use:

Set(currentScreen, App.ActiveScreen.Name)
