I'm creating a basic shopping app. I have a shopping cart based on a collection, displayed in a gallery. I want to add an edit function, so that the size/quantity can be updated directly in the shopping cart, before placing the order.
I inserted a dropdown box, with display mode = view (until the edit button is pressed), and default value = ThisItem.ItemSize (where ItemSize is the size field in the collection). However, the dropdown is blank.
In powerapps controls to the right, I can see that the default value is there correctly, picked up from the collection.
If I create a label, with ThisItem.ItemSize - it correctly displays the size.
I just can't get the drop down to have a visible default value and it's driving me mad! 🙂
