Hi,

I'm using a TreeListBox, with a simple datatemplate (an image an a textBlock).

When the user click on a item in the tree and then select a different area in the application (the tree lost the focus)

the selected tree item bacground becom a littel gray (using snoop i can see it's the ElementChrome.Background).

My problem is that the panel behind the TreeListBox have the same color and the selected item is no longer distingwish from all the other items.

so, How can i override just that color?

when the item is selected and not in foucos.

Thank you.

Hello,

The TreeListBoxItem backgrounds should show up ok unless you changed the TreeListBox.Background brush.  If you did change that, then this documentation topic tells how to override theme brush resources.  TreeListBoxItem uses the ListItemBackgroundSelectedNormalBrushKey and ListItemBorderSelectedNormalBrushKey brush resources when unfocused and selected.  You can override those per the documentation if you need it to be something else.
