In my canvas app, there is a gallery with subgallery.
The gallery's Items:
GroupBy(colChecklist,"ChecklistItemGroup","GroupByTitle")
The child-gallery's items:
ThisItem.GroupByTitle
Under each parent gallery item (the grey bar below) there is a checkbox. When this checkbox is checked, I would like to check/uncheck all the checkbox in child gallery (item 1, item 2 below).
How can I achieve it?
Hi @hongkong
Assuming your parent gallery checkbox name is Checkbox_Parent and your child gallery checkbox name is Checkbox_Child.
Then you can make the default property of Checkbox_Child into:
Checkbox_Parent.Value
So that when you check/uncheck the Checkbox_Parent, the Checkbox_Child will follow.
You can see more info here:
