WPF: Disable ListBox, but enable scrolling
If you look in to the control template of the ListBox, there is a ScrollBar and ItemsPresenter inside. So Make the ItemsPresenter Disabled and you will get this easily. Use the bellow Style on the ListBox and you are good to go.
<Style x:Key="disabledListBoxWithScroll" TargetType="{x:Type ListBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBox}">
<Border x:Name="Bd" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Padding="1">
<ScrollViewer Padding="{TemplateBinding Padding}" Focusable="false">
<ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" IsEnabled="False" IsHitTestVisible="True"/>
</ScrollViewer>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
</Trigger>
<Trigger Property="IsGrouping" Value="true">
<Setter Property="ScrollViewer.CanContentScroll" Value="false"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
On the ListBox use the Style
<ListBox Style="{DynamicResource disabledListBoxWithScroll}" ..... />
sorry it has been almost two years, but I think this solution that uses DataTrigger is even simpler. How to disable a databound ListBox item based on a property value?
I found that putting a disabled ListBox in a ScrollViewer with auto scrolling enabled gives the desired effect.
