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

<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.ItemTemplate>
</syncfusion:TreeViewAdv>

Example:
private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
object saveitem = sender;
int itemlevel = 1;
for (int i = 0; i < 100; i++)
{
if ((sender as TreeViewItemAdv).ParentItemsControl is TreeViewAdv)
{
sender = saveitem;
break;
}
else
{
itemlevel++;
sender = (sender as TreeViewItemAdv).ParentItemsControl as TreeViewItemAdv;
}
}
//TreeView Root Level Items
//By using the VisualUtils to find the SelectedRectangle.
SelectRectangle rectangle = VisualUtils.FindDescendant((sender as TreeViewItemAdv) as Visual, typeof(SelectRectangle)) as SelectRectangle;
Border border = (sender as TreeViewItemAdv).Template.FindName("Bd", (sender as TreeViewItemAdv)) as Border;
border.Width = (sender as TreeViewItemAdv).ActualWidth;
border.Margin=new Thickness(-(rectangle.ActualWidth*itemlevel),0,0,0);
border.Padding=new Thickness(rectangle.ActualWidth*itemlevel,0,0,0);
Binding RootBinding = new Binding(){Source = border,Path = new PropertyPath("Background"),Mode = BindingMode.TwoWay};
rectangle.SetBinding(SelectRectangle.FillProperty, RootBinding);
// TreeView SubItems
foreach (var item in VisualUtils.EnumChildrenOfType(sender as TreeViewItemAdv, typeof(TreeViewItemAdv)))
{
SelectRectangle subrectangle = VisualUtils.FindDescendant((item as TreeViewItemAdv) as Visual, typeof(SelectRectangle)) as SelectRectangle;
Border subborder = (sender as TreeViewItemAdv).Template.FindName("Bd", (item as TreeViewItemAdv)) as Border;
subborder.Width = (sender as TreeViewItemAdv).ActualWidth;
border.Margin = new Thickness(-(rectangle.ActualWidth * itemlevel), 0, 0, 0);
border.Padding = new Thickness(rectangle.ActualWidth * itemlevel, 0, 0, 0);
Binding SubBinding = new Binding() { Source = subborder, Path = new PropertyPath("Background"), Mode = BindingMode.TwoWay };
subrectangle.SetBinding(SelectRectangle.FillProperty, SubBinding);
}
}
