Determines whether all items of a repeating section or table satisfy a condition. If so ‘true’ is returned, if not ‘false’ is returned.
The All function tests whether all elements in a collection satisfy a given condition. It does this by accepting a predicate, which is a function that returns a boolean value, true or false, based on a condition.
For example, suppose you have a repeating section and you want to check if ChoiceField1 = “First Choice” for every item in the repeating section. You can pass a function to All that checks this condition. If every item satisfies the condition, All will return true. If any item does not satisfy the condition, All will return false.
