Introduction
Many people prefer to see checkboxes instead of the highlighting in a list box. There is a way to do this in XAML that does not require any change in ItemsSource, such as a property to bind to the IsChecked property of the Checkbox.
Design
The following is an example of the XAML that will replace the highlighting of ListBoxItem with a CheckBox:
<ListBox Margin="15"
VerticalAlignment="Stretch"
ItemsSource="{Binding Items}"
SelectionMode="Multiple">
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<CheckBox Margin="5,2"
IsChecked="{TemplateBinding IsSelected}">
<ContentPresenter />
</CheckBox>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.Resources>
</ListBox>
It requires the replacement of the ListBoxItem Template with a simple Template where the ContentPresenter is just contained in a CheckBox which has its IsChecked property bound to the ListBoxItem IsSelectedProperty. One of the things that this Template does is remove the Triggers that do the highlighting. Instead the highlighting depends on the Triggers for the CheckBox.
