aber ich brauche meine Scrollbar wie diese

ich diesen Raum müssen in der rechten unteren Ecke mit ho gefüllt werden aussehen werden rizontal oder vertikale scroll bar. Ist es möglich in wpf ??

Unten ist die maßgeschneiderte Stil für die Scrollbar

<local:ThicknessConverter x:Key="ThicknessConverter" /> 
    <Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}"> 
     <Setter Property="SnapsToDevicePixels" Value="True"/> 
     <Setter Property="OverridesDefaultStyle" Value="true"/> 
     <Style.Triggers> 
      <Trigger Property="Orientation" Value="Horizontal"> 
       <Setter Property="Width" Value="Auto"/> 
       <Setter Property="Height" Value="18" /> 
       <Setter Property="Template" 

        Value="{StaticResource HorizontalScrollBar}" /> 
      </Trigger> 
      <Trigger Property="Orientation" Value="Vertical"> 
       <Setter Property="Width" Value="18"/> 
       <Setter Property="Height" Value="Auto" /> 
       <Setter Property="Template" 

        Value="{StaticResource VerticalScrollBar}" /> 
      </Trigger> 
      <Trigger Property="Name" Value="PART_VerticalScrollBar"> 
       <Setter Property="Margin" Value="{Binding RelativeSource={RelativeSource AncestorType=ScrollViewer},Converter={StaticResource ThicknessConverter}}"> 
       </Setter> 
      </Trigger> 

     </Style.Triggers> 


    </Style> 

und hier gibt es treeview Code

<telerik:RadTreeView x:Name="radTreeView" Background="#4E4E4E" Margin="0,0,456,0" Grid.Row="2" 
       ItemsSource="{x:Static local:MainWindow.AnimalCategories}" ItemPrepared="treeView_ItemPrepared" 
          ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Visible" Grid.RowSpan="2" Grid.ColumnSpan="2"> 
      <telerik:RadTreeView.ItemTemplate> 
       <HierarchicalDataTemplate ItemsSource="{Binding Animals}"> 
        <TextBlock Text="{Binding Category}" /> 
        <HierarchicalDataTemplate.ItemTemplate> 
         <DataTemplate> 

          <TextBlock Text="{Binding Name}"/> 

         </DataTemplate> 
        </HierarchicalDataTemplate.ItemTemplate> 
       </HierarchicalDataTemplate> 
      </telerik:RadTreeView.ItemTemplate> 

     </telerik:RadTreeView>

Unten finden Sie eine Möglichkeit, es zu tun ist:

XAML:

<ScrollViewer Height="400" Width="400" VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Visible" > 
    <ScrollViewer.Resources> 
     <local:ThicknessConverter x:Key="ThicknessConverter" /> 
     <Style TargetType="ScrollBar"> 
      <Style.Triggers> 
       <Trigger Property="Orientation" Value="Horizontal"> 
        <Setter Property="Margin" Value="{Binding RelativeSource={RelativeSource AncestorType=ScrollViewer},Converter={StaticResource ThicknessConverter}}"> 
        </Setter> 
       </Trigger> 
      </Style.Triggers> 
     </Style> 
    </ScrollViewer.Resources> 
</ScrollViewer> 

Converter:

public class ThicknessConverter : IValueConverter 
{ 
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     var scrollBars = FindVisualChildren<ScrollBar>(value as DependencyObject); 
     foreach (var scrollBar in scrollBars) 
     { 
      if (scrollBar.Orientation == Orientation.Horizontal) 
      { 
       return new Thickness(0, 0, 0, 0 - scrollBar.ActualHeight); 
      } 
     } 
     return new Thickness(0, 0, 0, 0); 
    } 

    public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject 
    { 
     if (depObj != null) 
     { 
      for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++) 
      { 
       DependencyObject child = VisualTreeHelper.GetChild(depObj, i); 
       if (child != null && child is T) 
       { 
        yield return (T)child; 
       } 

       foreach (T childOfChild in FindVisualChildren<T>(child)) 
       { 
        yield return childOfChild; 
       } 
      } 
     } 
    }   

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
    { 
     throw new NotImplementedException(); 
    } 
} 

OUTPUT:
