public partial class MainWindow : Window
{
private List<Employee> employees;
public MainWindow()
{
InitializeComponent();

employees.Add(new Employee { Id = "Header One", Name = "First" });
employees.Add(new Employee { Id = "Header Two", Name = "Second" });
employees.Add(new Employee { Id = "Header Three", Name = "Third" });
employees.Add(new Employee { Id = "Header Four", Name = "Fourth" });
employees.Add(new Employee { Id = "Header Five", Name = "Fifth" });
this.DataContext = this;
myListView.ItemsSource = employees;
CollectionView view = (CollectionView)CollectionViewSource.GetDefaultView(myListView.ItemsSource);
PropertyGroupDescription groupDescription = new PropertyGroupDescription("Id");
view.GroupDescriptions.Add(groupDescription);

我不知道实现这一点的最佳方法是什么，但我非常肯定它最终会以一次肮脏的黑客攻击而告终 从

所以它只是所选项目右侧的边框？如果将所选元素的边框颜色设置为白色，该怎么办？请尝试。。但它不会与ListView边框重叠。不管我设置的边界有多大@弗雷德莫：是的，太完美了！真不敢相信我错过了。。回答得好，谢谢@嗯八
