Screen that filters the next screen

[Anonymous]

Hi,

I have a sharepoint list in wich I have data of my aircraft fleet. I need my app to do these:

1. A main screen in which I select my location (attached: main screen1)

2. I want a second screen with all the aircrafts located in that place sorted by registration plate (main screen1 style)

3. Also I want a third screen with a browse gallery already sorted by the choice I made in screen 1 and screen 2 (attached: browse screen)

My question is: Is there any way to previously filter a screen with my selection in the prior screen?

Thank you very much

Hi @Anonymous 

Yes this could be achieved by setting up few variables. Please follow below steps:

1) Main Screen: You can set a variable with name "SelectedLocation"

Screen -> OnVisible: Set(SelectedLocation,"")

All the Button for different location:

Spain Button-> OnSelect: Set(SelectedLocation,"Spain")

France Button -> OnSelect: Set(SelectedLocation,"France")

2) On the Second Screen, please connect the data source with the data associated to your aircraft registration plate.

Suppose, the DataSource Name is "AircraftRegistration" and this contains a column named "Location"

Expression:

Filter(AircraftRegistration, Location = SelectedLocation)

If this data is displayed as a gallery(Gallery1) and based on gallery selected item, the third screen will be filtered.

3) Now the third screen, suppose the data source is "AircraftDetails", then your filter query will be modified as:

Filter(AircraftDetails,Location = SelectedLocation && AircraftRegistrationNumber = Gallery1.Selected.RegistrationNumber)

Hope this Helps!

Hi @yashag2255,

Thank you very much for your answer, is perfect 🙂

But I have a problem with the second screen:

The registration plates appear sometimes several times and I would like to have each plate only once. Is there a way to eliminate duplicate values?

Hi @Anonymous ,

Try using the Distinct() Function:

In your case:

Distinct(Filter(AircraftRegistration, Location = SelectedLocation), PlateColumnName)

This will give the distinct values of Plate that fits the condition in the filter.

Hi @Anonymous 

In that case, you can modify the expression as:

Distinct(Filter(AircraftRegistration, Location = SelectedLocation),PlateNumber)

With this, your third screen formula will be modified as:

Filter(AircraftDetails,Location = SelectedLocation && AircraftRegistrationNumber = Gallery1.Selected.Result)
