Gallery Transition

Posted on by Community Power Pla... Microsoft Employee

In a previous message by another user the Power Apps Hero stated that Power Apps does not support transition to a screen based on the contents of a field in the Gallery. However, one could transition to a Screen 1 if 'Screen 1' was in the Gallery. Where as if a specific title (i.e. Bus Driver), was in the Gallery a New Employee edit form screen would open. But, if different specific title (i.e. School Teacher) appeared the Transfer Employee edit form screen would open.

Can anyone provide clarification as to whether the above transition configuration is possible?

If(ThisItem.Value = "Screen1",Navigate(Screen1,ScreenTransition.Fade), ThisItem.Value = "Screen2",Navigate(Screen2,ScreenTransition.Fade),ThisItem.Value = "Screen3",Navigate(Screen3,Fade))

Yep, totally possible. You could even re-write that formula if you like, like this

Switch(ThisItem.Value, "Screen1",Navigate(Screen1,ScreenTransition.Fade), "Screen2",Navigate(Screen2,ScreenTransition.Fade), "Screen3",Navigate(Screen3,Fade) )

So, how would I edit the below to transition to 'New Employee' form if 'Teacher, Doctor, Butcher or Athlete' appear in the title field of the Gallery. And, if 'Bartender, Astronaut, or Zookeeper nothing happens - if possible trigger an error or help message like 'No Update Allowed' form,

Switch(ThisItem.Value, "Screen1",Navigate(Screen1,ScreenTransition.Fade), "Screen2",Navigate(Screen2,ScreenTransition.Fade), "Screen3",Navigate(Screen3,Fade) )

Like this
Switch(ThisItem.Title, "Teacher",Navigate('New Employee',ScreenTransition.Fade), "Doctor",Navigate('New Employee',ScreenTransition.Fade), "Butcher",Navigate('New Employee',ScreenTransition.Fade), "Athlete",Navigate('New Employee',ScreenTransition.Fade), Notify("No Update Allowed", NotificationType.Error) )
Notify can also be:
- Screen transition to an empty screen with a label that says "No Update Allowed", or
- A PopUp, but this is more work

Hi @Anonymous :
Do you want to add navigation buttons in the gallery？
case1:ThisItem.Title in ["Teacher", "Doctor", "Butcher" ,"Athlete"]
Navigate to 'New Employee' screen
csse2:ThisItem.Title not in ["Teacher", "Doctor", "Butcher" ,"Athlete"]
Pop up error message
If so,I'v made a test for your reference:
1\My data source is a collection:

ClearCollect(GalleryTransition,{Title:"Teacher"},{Title:"Doctor"},{Title:"Butcher"},{Title:"Athlete"},{Title:"Bartender"},{Title:"Astronaut"},{Title:"Zookeeper"})

2\Add a gallery
3\Add an arrow into this gallery and set it's OnSelect proeprty to:

If( ThisItem.Title in [ "Teacher", "Doctor", "Butcher", "Athlete" ], Navigate('New Employee'), Notify("No Update Allowed") )

Best Regards,
Bof

I entered the following.

I get the following error message - "Name isn't valid. This identifier isn't recognized".

Power Apps apparently doesn't like that I'm referencing the contents of and Html Text field in the Gallery.

BTW, I'm using Html text fields so that I can create a black label and blue content (i.e. - Cert Title: Professor)

Thoughts on how to correct the error?

If(
ThisItem.HtmlText1 in [
"FitnessPEB",
"Medical",
"SCBA Fit Test",
"Live Fire Refresher",
],
Navigate(CertQualDtlScrn),
Notify("No Update Allowed")
)

Use two standard labels instead of one HTML.text label in your gallery and colour them accordingly. Then reference the label that has "FitnessPEB", "Medical", etc in your formula

A small edited, see below, did the trick. Thank you!

If(
ThisItem.Title in [
"Title1",
"Title2",
"Title3",
"Title4",
],
Navigate(...Scrn),
Notify("No Update Allowed")
)
