How to highlight the entire TreeViewItemAdv row when it is selected or mouseover in WPF TreeViewAdv?

<syncfusion:TreeViewAdv x:Name="tree"
                        ItemsSource="{Binding TreeItems}"
                        MouseOverBackground="GreenYellow"
                        SelectedBackground="SkyBlue">

    <syncfusion:TreeViewAdv.ItemContainerStyle>
        <Style TargetType="{x:Type syncfusion:TreeViewItemAdv}">
            <EventSetter Event="Loaded"
                         Handler="FrameworkElement_OnLoaded" />
        </Style>
    </syncfusion:TreeViewAdv.ItemContainerStyle>

</syncfusion:TreeViewAdv>

private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
    object saveitem = sender;
    int itemlevel = 1;

    // Calculate the nesting level of the TreeViewItemAdv
    for (int i = 0; i < 100; i++)
