Hi,

I want to render a Tree with transparent background (for printing purposes).

Setting

TreeListView.Background = System.Windows.Media.Brushes.Transparent;

is ok to have all the cells being transparent.

Want do I have to do, to have the Header part of the Tree transparent ?

Thanks !

Hello,

There isn't a direct property you can set to make the Header transparent.  The TreeListViewColumnHeader control's Background property is currently set via a Setter like:

<Setter Property="Background" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ListHeaderBackgroundNormalBrushKey}}" />

You'd probably need to declare a Transparent Brush in the TreeListView.Resources with the AssetResourceKeys.ListHeaderBackgroundNormalBrushKey key to override our theme's default value for that key.  Then that would hopefully do the trick.
