Answer 2

はのControlTemplateを変更しよう：

<ControlTemplate TargetType="ListBox"> 
    <Grid> 
    <Grid.RowDefinitions> 
     <RowDefinition /> 
     <RowDefinition Height="Auto"/> 
    </Grid.RowDefinitions> 
    <ScrollViewer x:Name="ScrollViewer" Grid.Row="0" 
        BorderBrush="{TemplateBinding BorderBrush}" 
        BorderThickness="{TemplateBinding BorderThickness}" 
        Background="{TemplateBinding Background}" 
        Foreground="{TemplateBinding Foreground}" 
        Padding="{TemplateBinding Padding}"> 
      <ItemsPresenter/> 
     </ScrollViewer> 
     <HyperlinkButton Content="Add More" FontSize="25" 
      Grid.Row="1" Name="hybtnAddMerchant" Click="hybtnAddMerchant_Click" VerticalAlignment="Bottom"/> 
    </Grid> 
</ControlTemplate>
