I have 1 Listbox it takes items from TextBox, when an item is added to the listbox and the application is closed, upon opening the application the item added to the listbox will still be present.
User opens application.
User adds item called "Item 1" to listbox using button.
User closes application.
User opens application again and sees that "Item 1" is still in the listbox, and the added item hasn't been lost by the application closing.
