Hi,

I’m facing a problem that I can’t navigate my form to the correct screen based on the pre-populate selection from a gallery.

Basic background: The form will pre-populate the language in the language drop-down selected from the Sharepoint page. There are multiple screens pointing to different language. When the user selected a language in the sharepoint page (i.e French), the form will open and should navigate to the correct French screen.

Right now the language drop-down is working good and changed to French, but the form is still displaying the default form - English. I have to click French again and the form will navigate to the French screen.

I used the following formulas:

language drop-down :

If( languageDataCardValue.selected.value = “English”, Navigate(English, Screentransaction.cover), languageDataCardValue.selected.value = “French”, Navigate(French, Screentransaction.cover))

default:

if( !(param=“”),param=‘language’,parent.default)

Any help will be much appreciated!

@Shavesbsb - As you are receiving the parameter from outside and setting the parameter to default property of the dropdown it just sets the value, but it will not fire the on change function, that's the reason where your form was not navigating to the right screens. You need to write the same logic in app on start to check if your parameter language value is English or French and then navigate to respective screens.

@Shavesbsb On the screen onvisible property use below code.
If( param(“language”) = “English”, Navigate(English, Screentransaction.cover), param(“language”) = “French”, Navigate(French, Screentransaction.cover))

@Bilakanti Thank you! but Onvisible shows that “Navigate can’t be used here since it would automatically navigate away from this screen”. Any ideas?

Hi @Shavesbsb ,

Assuming you are not already on the English or French page - put this OnSelect of the drop-down

Switch( Self.Selected.Value, "French", Navigate(French, Screentransaction.Cover), "English", Navigate(Englich, Screentransaction.Cover) )

or are you wanting to Navigate automatically based on the Parameter - if so, where is the parameter coming from ?

As an example if this is deep-linked with the Parameter "Language", then StartScreen

If( IsBlank(Param("Language")), YourIntroScreen, Param("Language") = "English", English, Param("Language") = "French", French, YourIntroScreen, )
