I know that I can set the alternating row colour of list box by defining Item control style like this one
https://stackoverflow.com/a/3567894/1241992
I want to know how can I set this using Blend for Visual Studio. When I am designing my layout in Blend, I do not want to edit code and define my styles that way. I want to visualize and create my styles and I am sure there must be some way of doing it but I cannot figure out how. Strange thing is even if I try to edit this already defined style, I can not create another trigger property which defines AlternationIndex via Blend.
