Change selection color in hierarchical TreeView

Question

I have a TreeView with a HierarchicalDataTemplate.

<HierarchicalDataTemplate x:Key="treeViewItemTemplate" ItemsSource="{Binding GetChildren}"> <DockPanel Margin="0,8,8,0"> <Image Source="{Binding GetImage}" Width="16" Height="16" /> <local:MonitorTriStateCheckBox Margin="4,0,0,0" IsChecked="{Binding IsChecked}" Click="CheckBox_Clicked" Tag="{Binding UniqueKey}" Style="{DynamicResource CheckBox}"></local:MonitorTriStateCheckBox> <TextBlock Margin="4,0,0,0" Text="{Binding Name}" Style="{DynamicResource TextBlock}"> </TextBlock> </DockPanel> <HierarchicalDataTemplate.Triggers> <Trigger Property="TreeViewItem.IsSelected" Value="True"> <Setter Property="TreeViewItem.Background" Value="Orange" /> </Trigger> </HierarchicalDataTemplate.Triggers> </HierarchicalDataTemplate> 

As you can see in the code, I set the selected TreeViewItem trigger, but this does not affect. I tried this:

 <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" /> <Setter Property="Visibility" Value="{Binding IsVisible, Mode=TwoWay}" /> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Background" Value="Orange" /> </Trigger> </Style.Triggers> </Style> </TreeView.ItemContainerStyle> 

But this also did not affect.

Does anyone have an idea what to do to change the color of the hightlight TreeViewItem?

Try it...

 <TreeView.Resources> <SolidColorBrush Color="Green" x:Key="{x:Static SystemColors.HighlightBrushKey}"/> </TreeView.Resources>
