WPF Border and Header alignment

Question

Got two problems here in my XAML code.

<Grid Margin="20">

        <ListBox x:Name="lbChampToSelect" ItemsSource="{Binding Lst}" HorizontalContentAlignment="Stretch" Grid.IsSharedSizeScope="True">
        <Border Background="FloralWhite" BorderBrush="Silver" BorderThickness="1" CornerRadius="3,3,3,3">                
            <ListBox.Template>
                <ControlTemplate>
                    <DockPanel LastChildFill="True">
                    <Grid Margin="5,2" DockPanel.Dock="Top" >
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="100" SharedSizeGroup="Col1"></ColumnDefinition>
                            <ColumnDefinition Width="100" SharedSizeGroup="Col1"></ColumnDefinition>
                        </Grid.ColumnDefinitions>
                        <Label Grid.Column="0">Libellé</Label>
                        <CheckBox IsChecked="False" Grid.Column="1"/>
                    </Grid>
                    <ItemsPresenter></ItemsPresenter>
                    </DockPanel>
                </ControlTemplate>                    
            </ListBox.Template>

            <ListBox.ItemTemplate>                    
                <DataTemplate>
                    <Grid Margin="5,2">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition  Width="100" SharedSizeGroup="Col1"/>
                            <ColumnDefinition Width="100" />
                        </Grid.ColumnDefinitions>
                        <TextBlock Margin="0,0,10,0" Text="{Binding Libelle }" Grid.Column="0" />
                        <CheckBox IsChecked="False" Grid.Column="1"/>
                    </Grid>
                </DataTemplate>                    
            </ListBox.ItemTemplate>
        </Border>
    </ListBox>

</Grid>

First : whatever I try, I cannot align the header and the columns containing checkboxes (with a text labelling the checkbox it's worth). At the end, the header checkbox is supposed to check all the subsequents.

Second : I simply try to have a border on my entire listbox including the header but I got a xaml error saying the member Template is not accessible or does not exists.

Thx for your answers.

Otherwise, by using a ListView you can have header for items :

<ListView Margin="10" x:Name="lbChampToSelect" ItemsSource="{Binding Lst}" HorizontalContentAlignment="Stretch" Grid.IsSharedSizeScope="True" BorderBrush="Silver"
                 BorderThickness="1">
<ListView.Resources>
    <Style TargetType="ListViewItem">
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    </Style>
    <Style TargetType="CheckBox" BasedOn="{StaticResource {x:Type CheckBox}}">
        <Setter Property="HorizontalAlignment" Value="Center"/>
    </Style>
</ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Libelle" Width="120" DisplayMemberBinding="{Binding Libelle}" />
            <GridViewColumn Width="50">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox IsChecked="{ Binding IsChecked}"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
                <GridViewColumn.Header>
                    <CheckBox/>
                </GridViewColumn.Header>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>
