title: How can I speed up the rendering of my WPF ListBox?
body: <p>I have a WPF ListBox control <a href="http://github.com/jcbozonier/alloy/blob/2e82343b4b0739eb32ff3fd63354decbe08fc452/IronTwit/Alloy/Alloy.UI/Views/MainView.xaml" rel="nofollow noreferrer">(view code)</a> 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?</p>
