COMPONENTS: Create a Collection in a Component?



I want to create a reusable tracking component. Click a button, collect a timestamp, click the button again, collect another timestamp, etc.


I don't know how to approach this problem since "...PowerApps doesn't support collections in components".


Is there a way to:

  • Reuse the component across different app screens
  • Collect these timestamps from each screen/component to the same Collection in the App

Would I use a Custom Output Property here and variables?

I created a Component and inside that added a button. I wrote "Collect(TimeStamp,Now())" on the OnSelect method of the button. Also I used the components in multiple screen and it is working. I also exported the component and imported in another App and it is working. May be you try using collect command in your component.

Hi @seadude ,

Do you want to set a control's OnSelect inside component to Collect collection?

I've made a similar test and found that it is feasible.

Please note that component is an experimental control, so its function is improving.

Once in a while, its function will update. The doc that you listed wrote six months ago, some new functions may not update.


Here's my test for your reference:

1)Create a component, set a button 's OnSelect:



2)Insert this component in screen1 and screen28141.PNG




3)Set a gallery's Items to this collection: a

4)Run this app

If I click the button in screen1 and click the button is screen2, the collection will update successfully.8143.PNG

Hey @seadude 


You can try to use the below expression on the OnSelect property of the button inside the component. I carried a test on my side and this works fine. Please refer to below screenshots:
Expression Used:
Collect(MyCollection,{Title:Concatenate("Test",Text(CountRows(MyCollection)+1)),TimeStamp: Now()})
The highlighted part collects the timestamp.
When imported on multiple screens, this will point to the same collection.p.png




Hope this Helps!
