我试图在我的wpf应用程序中为业务对象定义一个dataTemplate,其集合绑定到ListBox.

<UserControl.Resources>
    <DataTemplate x:Key="ResizedItemsDataTemplate" DataType="{x:Type resizer:ResizeMonitorItem}">
              <Border x:Name="bdr" BorderBrush="Blue" 
                                     BorderThickness="1" 
                                     CornerRadius="2" 
                                     Width="auto"
                                     HorizontalAlignment="Stretch"
                                     VerticalAlignment="Stretch">
                    <Grid Margin="2">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="14"></RowDefinition>
                            <RowDefinition Height="14"></RowDefinition>
                        </Grid.RowDefinitions>


                        <TextBlock Grid.Row="0" Text="{Binding SaveAsFileName}"></TextBlock>
                        <TextBlock Grid.Row="1" Text="{Binding ResizedImageFilePath}"></TextBlock>
                    </Grid>
             </Border>
    </DataTemplate>
</UserControl.Resources>
<Grid VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0">    
    <Border BorderThickness="0,0,0,5" BorderBrush="DarkGray" >
        <ListBox x:Name="ListBoxResizeItems" ItemsSource="{Binding Path=ResizeItems}" BorderThickness="0" ItemTemplate="{DynamicResource ResizedItemsDataTemplate}">
        </ListBox>
    </Border>
</Grid>

如何使用x:Name = bdr定义边框以跨越每个列表框项的整个宽度？目前它只跨越其中的文本块,不需要填充listboxitem的整个宽度,并且每个listboxitem也有所不同.
