Is there a way to control the color/style of the expand button (dropdown arrows) for layers and group layers displayed in the Legend control? I have tried going through all the control templates and can't seem to find any that controls that item. If you have a dark background set for the control, you can't see the default black arrows that you can click on to expand the layer list, so I just want to change them to a lighter color. Am I missing something?
Of course, after I post I find it. It is in the "Generated Item Container" template, part of the TreeViewExtended template. The ExpanderButton is there, which you can edit the template of to get to the arrow shape.
