I have a WPF ListBox control (view code) and I am keeping maybe like 100-200 items in it. Every time the ObservableCollection it is bound to changes though it takes it a split second to update and it freezes the whole UI. Is there a way to add elements incrementally or something I can do to improve the performance of this control?
