So, How to create this type of collection in PowerApp Application collection from SharePoint DataSource (SharePoint List)

Answer 1

I happened upon this question/answer and others which I felt were not clear. While the instructions are correct, the reason WHY you need to do this is not. In PowerApps currently, you need to create a link to a SharePoint datasource and connect your Collection to it before you try to use it. However, trying to do this on the OnStart event does not properly populate things. So doing a temporary few steps as indicated in the answer fixes the problem.

To create a Collection variable (myCollection) that links to and holds the contents of a SharePoint list (mySPList) do the following steps:

1. In your application, add a datasource to your application that connects to your SharePoint list (e.g. mySPList)
2. Create a temporary page with a button on it.
3. Change the OnSelect action of that button to be: ClearCollect(myCollection,mySPList)
4. Run the app and click that button
5. Stop the app and go back to your OnStart event for your main application and again put in: ClearCollect(myCollection,mySPList)

Steps 1-4 create a Collection that includes the fields/data from your SharePoint list and allows it to be referenced ANYWHERE in your application properly. Step 5 (which is what you probably tried first) allows you to have your list updated at start but does not actually create the list for your application at development time.

You can easily test this now by creating another temporary Data Table and changing the Items property for that table to be the name of your Collection (e.g. myCollection). It will now display the contents of your SharePoint List.

This is very handy for having your application access semi-static content that is not updated by the application (e.g. context-sensitive help fields). It drastically improves the speed of this for your applications where you want to populate a text or HTML field based on Lookups (e.g. LookUp(HTMLHelp,Parent.DisplayName=FieldName,HTML)
