#993 – Default Control Template for a ListBox

The default control template used for a ListBox (in version 4.5 of the .NET Framework) is shown below.  The template is included within a style that includes some other default property values.

The core structure of the ListBox is simple–an ItemsPresenter, within a ScrollViewer and surrounded by a Border.

        <Style x:Key="lbDefaultStyle" TargetType="{x:Type ListBox}">
            <Setter Property="Background" Value="White"/>
            <Setter Property="BorderBrush" Value="#FFABADB3"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
            <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
            <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
            <Setter Property="ScrollViewer.CanContentScroll" Value="True"/>
            <Setter Property="ScrollViewer.PanningMode" Value="Both"/>
            <Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="Template">
                    <ControlTemplate TargetType="{x:Type ListBox}">
                        <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="True">
                            <ScrollViewer Focusable="False" Padding="{TemplateBinding Padding}">
                                <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                            <Trigger Property="IsEnabled" Value="False">
                                <Setter Property="Background" TargetName="Bd" Value="White"/>
                                <Setter Property="BorderBrush" TargetName="Bd" Value="#FFD9D9D9"/>
                                    <Condition Property="IsGrouping" Value="True"/>
                                    <Condition Property="VirtualizingPanel.IsVirtualizingWhenGrouping" Value="False"/>
                                <Setter Property="ScrollViewer.CanContentScroll" Value="False"/>

        <ListBox Name="lbActors" Margin="15,5" Width="200" Height="200"
                 ItemsSource="{Binding ActorList}"
                 Style="{DynamicResource lbDefaultStyle}"/>
