Pass Data Between Screens in a Canvas App | Working with Galleries, Forms and Global Variables
Показать описание
It’s common to need to pass data between screens in a Power Apps Canvas App, especially when working with galleries and forms. How do you do it?
In this video, I’ll show you the basic theory behind global variables and how they can be used to store values in the app’s memory. Then in a hands-on tutorial, we’ll implement the logic to store the item that was clicked on in a gallery (Screen #1), and retrieve it and use it in a form (Screen #2). It’s easier than you think!

03:34 – Retrieving a global variable and assigning it to the Item property of a form in a Canvas App
04:18 – Viewing global variables used by a Canvas App
