How to toggle CSS with conditional

[CosmanAgraz]

I'm trying to implement a module very similar to the one shown here

I have a list of items, and multiple items can be selected. However, when I add a conditional to a class prop, the CSS does not update, only after a page refresh.

I managed to fix this issue by forcing a page refresh, but performance slowed waaaayyy down and I'm just wondering why is it that Image src prop can be updated without needing to refresh but not the class prop.

If you could share a bit of your code, would help us understand what's going on. Class bindings should generally work in lists.

@rigor789 thanks for the response! I fixed this issue by updating the .class property of the View (the XML element) in the View-Model function which is executed when a button is tapped.
