How to Generate Dynamic Year List

[itsmeqp]

I am wondering if there is a way to generate dynamic list within PowerApps. 

My scenario is if I define  a StartYear, I would like the app to generate a collection of years from StartYear to EndYear, or in my specific case, Year(Now()). I am trying to avoid manually hardcoding the years.  

Example:

StartYear = 2017

CollectionYear would contain:

• 2017
• 2018
• 2019

then when New Years rolls around, 2020 would be included in the list.

This would be tough to do in PowerApps, but could easily be done in a Flow attached to the PowerApp.  Then return the collection to PowerApps.

The Flow -

• Initalize an Array variable,
• Build a Loop,
  • starting with the first year use the AddToTime to add a year,
  • save the year of the result,
  • if its equalto or greater than now exit the loop

Hi @itsmeqp 

To do this with PowerApps 

First create a collection - this would be the hardcoding part

Here you can go upto 100 based on the number of years difference between todays year and the year user enters

So if you think it would be max 50 - then below array should go to 50

ClearCollect(ColNum,{Val:0},{Val:1},{Val:2},{Val:3},{Val:4},{Val:5},{Val:6},{Val:7},{Val:8},{Val:9},{Val:10})

Execute the above on App On Start

Then 

To get the years collection

Clear(colYears);ForAll(ColNum,If(Val<=(Year(Now())-2017),Collect(colYears,{Years:Year(Now())-Val})))

where 2017 - can be replaced by the data (numeric) that user enters

No prob.
1. On App start set a variable to your start date. Add variable to collection.
2. Add a timer, OnStart increment your variable and add to collection.
3. Timer repeat If( var_StartYear = Year(Today()), false, true)
4. Hide Timer.
EDIT 5. Timer autoStart needs to be set as well If( var_StartYear = Year(Today()), false, true) or it will keep counting.

hi! sorry to resurrect an old discussion but wanted to add my solution in case anybody else runs into the same issue. its very easy, just a sequence of the next 3 years starting now. 

Sequence(3, Year(Now()), 1)

generates a table so works with galleries, tables, dropdowns, etc.  let me know if it works with u!

@itsmeqp - Use the Sequence function along with subtracting the start year from the current year to get your range of numbers in a Table which you can use in a dropdown, etc.

Sequence(
    // Dynamic number of years 
    (Year(Now()) -
    // One less than the start year
 2017),
    // Start year
    2018
)

This will return a table like: [2018, 2019, 2020, 2021, 2022]

To add on to this, I needed all years from 2018 until the current year, I used the following code:

Sequence((Value(Year(Today())) - 2018) + 1, 2018, 1)
