I am having an issue with everything that has been said here. At first I could not get the item to be selected and/or highlighted. I got it working now with base.synchronizeproperties(); however, the behavior is unpredictable. When my mouse passes over an item it is highlighted as it should be by shadowing out the element but when I actually click on it (in which case it should turn gold) nothing happens. It looks as if it is selected for an almost undetectable split second but then is quickly unselected. At times it does work but once one item is selected nothing else can be selected for a while until the program crashes with due to a null in my selected index changed event.
