ListView Selected Item Not Working
 
I have a listview that when I select an item, it populates a details view. I
want to show the item that was selected in the listview by changing it to
yellow. Trouble is, the selected item does not show as yellow until I've
clicked the same item two times. What am I doing wrong on the selected item
that keeps it from changing to yellow until the item is clicked two times?
Also, I have to set the listviews selectedIndex in the SelectedIndexChanging
event. Not sure if this is related to the color problem, but is that what you
are supposed to do?
