I am using VS Professional 2015, DevCraft Ultimate version 2016.2.613, UI for WPF RadListBox. Using Office2013 Theme, I wish to override the color of a RadListBox's selected RadListBoxItem. I also want to override this background color for mouseover. Currently these are an orange color and I want to change that. My understanding is that the RadListBoxItem control template has a border named "SelectedVisual" and I need to override its background color. Maybe something similar for mouseover? (haven't got there yet). My problem is that I can't figure out how to do any of this using Expression Blend 2015. I'm on the Objects and Timeline pane and when I right click on my RadListBox I don't see an option for "Edit Additional Styles" which I think would get me to the RadListBoxItem's style. I do see "Edit Additional Templates" but nothing I try around that option is getting me to the "SelectedVisual" border. I would welcome any info on 1) how to do this in Blend or 2) any recommended alternative method to override RadListBoxItem's selected and mouseover background colors. Please see attached imagesto better visualize what I'm trying to do.
