UpdateIf updating all rows in a collection

Posted on by AppGenius

I have a collection used as a data source for a gallery, with two columns question num and visibility indicator. I’m updating this collection such that when the question number is between two numbers, it updates the visibility indicator to No. This logic is not working though. While debugging I set the UpdateIf condition to a specific question number = 13. It worked this time but updated all the rows in the collection. The code is on the OnSelect of a button. I also used ForAll but it doesn’t update anything at all. For example, if my current question is 3 and next question is 15, I want question 14 to hide in the gallery using its visibility indicator and hence I need to set it to No.

Hi

Its not realistic to try to explain, when even in your explanation you share no code no anything.

Its realistic to share your stuff so we can help you.

Can you share what you have done so far and what you want to achieve? It might be easy to understand by looking at the code instead of just plain explaination.

Hi AppGenius,

This is the basic code that you would use to make question 14 hidden.

UpdateIf( YourCollection, 'question num' >= 3 && 'question num' <= 15, { 'visibility indicator': false } )

If you could give more details as to the formula that you've used, that would be helpful.
