set highlighter for AdvSmoothImageListBox

when I move the mouse over an image item in AdvSmoothImageListBox, it will be highlighted. I can check, which item is highlighted, eg. for highlighting lines in an corresponding grid.
AdvSmoothImageListBox --> my Grid

I would like to do this otherwise also.
Move the mouse over "my Grid" should highlight the corresponding AdvSmoothImageListBox-item.
my Grid --> AdvSmoothImageListBox

Doing this with the "selected item"-frame is no solution because I need the "selected item"-frame and the highlighter-frame at the same time.
