Question
You have a canvas app that allows users to view, select, and purchase products. The app uses a Gallery control to display products and checkboxes that allow users to select products.
When users select items from the product catalog, they move to a different screen to complete a purchase.
Users must be able to clear all product selections when they click the button.
You need to configure the button.
What should you do?
- A. Use the Reset(Control) formula and pass the gallery control as a parameter to the Reset formula.
- B. Use the Reload(Control) formula and pass the gallery control as a parameter to the Reload formula.
- C. Use the ForAll() function to iterate through each item of the Gallery and clear user selections.
- D. Set the OnCheck value to populate a collection and the OnUncheck value to remove the item from the collection. Clear collection when the user selects the button. Correct
Explanation
Option D is correct because it involves using the OnCheck and OnUncheck properties of checkboxes to manage a collection that tracks selected products. Clearing this collection when the button is clicked effectively resets all product selections.
