记录下WPF中如何进行itemscontrol中进行分隔符的代码

 XAML的代码

 <ItemsControl x:Name="If" lternationCount="{Binding Path=LocationNums.Count}"
                                            ItemsSource="{Binding LocationNums}">
                                <ItemsControl.ItemsPanel>
                                    <ItemsPanelTemplate>
                                        <StackPanel
                                            HorizontalAlignment="Stretch"
                                            VerticalAlignment="Stretch"
                                            Orientation="Horizontal" />
                                    </ItemsPanelTemplate>
                                </ItemsControl.ItemsPanel>
                                <ItemsControl.ItemTemplate>
                                    <DataTemplate>
                                        <Border x:Name="Bd" BorderBrush="Black" BorderThickness="{Binding RelativeSource={RelativeSource TemplatedParent},
                                            Path=(ItemsControl.AlternationIndex),
                                            Converter={StaticResource BorderThicknessConverter}}">
                                              <TextBox  Text="{Binding Content}" >
                                                </TextBox>
                                        </Border>
                                    </DataTemplate>  
                                </ItemsControl.ItemTemplate>
                            </ItemsControl>

converter的代码

    public class BorderThicknessConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            int index = int.Parse(value.ToString());
            if (index != 0)
            {
                return new Thickness(1, 0, 0, 0);
            }
            else
            {
                return new Thickness(0, 0, 0, 0);
            }
           
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return null;
        }
    }
