Propagate ListBoxItem IsSelected trigger to child control

Question

I'm developing a CheckedListBox with self removable ListBoxItems. The problem is that an item only gets checked if the user clicks on the CheckBox area, which is kind of awkward.

How do I create ListBoxItem triggers (IsSelected) to check the checkboxes on a "DataSourced" ListBox? Eg:

Below is my control (all other code have been omitted for brevity):

<ListBox x:Name="executors" ItemsSource="{Binding Executors}" HorizontalAlignment="Left" Height="121" Margin="23,19,0,0" VerticalAlignment="Top" Width="362">
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Height" Value="30" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition />
                                <ColumnDefinition Width="30" />
                            </Grid.ColumnDefinitions>
                            <CheckBox Margin="4,8" IsChecked="{Binding Enabled}">
                                <ContentPresenter Content="{Binding Description}">

                                </ContentPresenter>
                            </CheckBox>
                            <Button Command="{Binding DataContext.RemoveExecutorCommand, ElementName=executors}" CommandParameter="{Binding}" Background="White" Height="22" Width="22" Grid.Column="1">
                                <Image Source="trash.png" Stretch="Fill" Width="14" Height="14" />
                            </Button>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

Executors is a ObservableCollection of Executor which has Enabled and Description as members.

Answer 1

For further reference for those who come across this same question, here's a working snippet I have done. I couldn't find any working sample anywhere, so this might be of much use.

The main idea here was to either propagate the selection event to the CheckBoxes, which sounds too much of a work, or to simple extend the CheckBox selection area to fit the ListBoxItem.

Below is a sample on how to achieve the second option:

<ListBox x:Name="executors" ItemsSource="{Binding Executors}" HorizontalAlignment="Left" Height="121" Margin="23,19,0,0" VerticalAlignment="Top" Width="362" ScrollViewer.VerticalScrollBarVisibility="Visible">
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Height" Value="30"/>
            <Setter Property="VerticalContentAlignment" Value="Stretch"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="9*"/>
                                <ColumnDefinition Width="1*" />
                            </Grid.ColumnDefinitions>
                            <CheckBox Content="{Binding Description}" IsChecked="{Binding Enabled}" VerticalContentAlignment="Center" Margin="4,0"/>
                            <Button Command="{Binding DataContext.RemoveExecutorCommand, ElementName=executors}" CommandParameter="{Binding}" Width="21" Height="21" Background="White" Grid.Column="1">
                                <Image Source="trash.png" Stretch="Fill" Width="14" Height="14" />
                            </Button>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

This should produce the following:
