How to disable highlighting on listbox but keep selection?
I am having trouble finding how to not allow my ListBox to highlight the item selected. I know that I didn't add a trigger to highlight the item.
<ListBox Name="CartItems" ItemsSource="{Binding}"
ItemTemplate="{StaticResource TicketTemplate}"
Grid.Row="3" Grid.ColumnSpan="9" Background="Transparent"
BorderBrush="Transparent">
</ListBox>
Solution 1:
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="IsSelected" Value="{Binding Content.IsSelected, Mode=TwoWay, RelativeSource={RelativeSource Self}}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<ContentPresenter/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
Solution 2:
Late answer, but there's a much better and simpler solution:
<ListBox>
<ListBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
</ListBox.Resources>
</ListBox>
This allows you to have a LisBox that looks just like an itemscontrol, but has support for selection.
Edit: How it works
This alters "colors of the system", in other words your windows theme, only for this ListBox and its children (we actually want to target the ListboxItem
).
For example hovering a ListboxItem
usually gives it a deep blue background, but here we set it to transparent (HighlightBrushKey).
Edit (30 June 2016):
It seems for latest Windows version this is not enough anymore, you also need to redefine InactiveSelectionHighlightBrushKey
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Transparent" />

Solution 3:
removing the highlighting completely feels very odd, as you dont know if you've selected anything, but here's a version of the control template that uses WhiteSmoke
(which is very subtle) instead of Blue
<Window.Resources>
<Style x:Key="ListBoxItemStyle1" TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment,
RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment,
RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="Padding" Value="2,0,0,0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"
Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" TargetName="Bd" Value="WhiteSmoke"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<ListBox HorizontalAlignment="Left" VerticalAlignment="Top" ItemContainerStyle="{DynamicResource ListBoxItemStyle1}">
<ListBoxItem Content="Item1"/>
<ListBoxItem Content="Item2"/>
<ListBoxItem Content="Item3"/>
<ListBoxItem Content="Item4"/>
<ListBoxItem Content="Item5"/>
<ListBoxItem Content="Item6"/>
</ListBox>
</Grid>

here's what worked for me.
<Style x:Key="ListBoxNoHighlight" TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Transparent"/>
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="Transparent"/>
</Trigger>
</Style.Triggers>
</Style>
