截图如下：
1、实现Converter 获取到listbox，并得到listitem在listbox中的index
public
class ItemContainerToZIndexConverter : IValueConverter { public
object Convert(object
value, Type targetType, object
parameter, System.Globalization.CultureInfo culture) { var
itemContainer = (DependencyObject)value; var
itemsControl = Tool.FindAncestor<ListBox>(itemContainer); int
index = itemsControl.ItemContainerGenerator.IndexFromContainer(itemContainer); switch
(index) { case
0: return
"A"; case
1: return
"B"; case
2: return
"C"; case
3: return
"D"; } return
null; } public
object ConvertBack(object
value, Type targetType, object
parameter, System.Globalization.CultureInfo culture) { throw
new NotSupportedException(); } } public
static class Tool { public
static T FindAncestor<T>(this
DependencyObject obj) where
T : DependencyObject { var
tmp = VisualTreeHelper.GetParent(obj); while
(tmp != null
&& !(tmp is
T)) { tmp = VisualTreeHelper.GetParent(tmp); } return
(T)tmp; } } |
2、<Style x:Key="ListBoxItemStyle1" TargetType="ListBoxItem">
使用数据绑定<TextBlock Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Converter={StaticResource converter}}"/>

3、ListBox中 ItemContainerStyle="{StaticResource ListBoxItemStyle1}
获取listboxitem在ListBox中的index并转换成abcd（数据绑定）,布布扣,bubuko.com
