如何更改列表框的文本框apearance取决于那里的对象？

Im new here, I have built this small uwp app using binded ObservableCollection to a Listbox, I wanted to know how to change apearence of Textbox inside listbox. To be precise I have ObservableCollection which is made out of objects and one property of this object is a boolean. "UsersWithIndications.CheckedInOrOut" = boolean. I want to make it so if this boolean is true, textbox of this single User becomes green, if its false = red... Can You please show me a direction of resolving this issue? How can I access each individual textbox in this Listbox? If any more code is required, please let me know!Im new here, I have built this small uwp app us
