如何禁止选择交互式ListBox项？

我的ListBox中的一些项目使用包含按钮和TextBox的模板。 如何才能使其无法从列表中选择这些项目，但仍然可以与按钮相互作用？

编辑：

我仍然需要能够选择此列表中的其他项目，而不是具有此模板的项目。

我们可以使用附加属性到ListBoxItem（在我实现之后，我找到了几乎完成相同的人 ）：

public class ListBoxItemEx { public static bool GetCanSelect(DependencyObject obj) { return (bool)obj.GetValue(CanSelectProperty); } public static void SetCanSelect(DependencyObject obj, bool value) { obj.SetValue(CanSelectProperty, value); } public static readonly DependencyProperty CanSelectProperty = DependencyProperty.RegisterAttached("CanSelect", typeof(bool), typeof(ListBoxItemEx), new UIPropertyMetadata(true, OnCanSelectChanged)); private static void OnCanSelectChanged(DependencyObject sender, DependencyPropertyChangedEventArgs args) { var item = sender as ListBoxItem; if (item == null) return; if ((bool)args.NewValue) { item.Selected -= ListBoxItemSelected; } else { item.Selected += ListBoxItemSelected; item.IsSelected = false; } } private static void ListBoxItemSelected(object sender, RoutedEventArgs e) { var item = sender as ListBoxItem; if (item == null) return; item.IsSelected = false; } } 

xaml：

视图模型：

 public class ViewModel : INotifyPropertyChanged { #region INotifyPropertyChanged values public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string propertyName) { if (this.PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion public List Elements { get; set; } public ViewModel() { this.Elements = new List(){ new Dummy() { CanSelect =true, MyProperty = "Element1"}, new Dummy() { CanSelect =false, MyProperty = "Element2"}, new Dummy() { CanSelect =true, MyProperty = "Element3"}, new Dummy() { CanSelect =false, MyProperty = "Element4"}, new Dummy() { CanSelect =true, MyProperty = "Element5"}, new Dummy() { CanSelect =true, MyProperty = "Element6"}, new Dummy() { CanSelect =true, MyProperty = "Element7"}, new Dummy() { CanSelect =true, MyProperty = "Element8"}, new Dummy() { CanSelect =false, MyProperty = "Element9"}, }; } } public class Dummy { public bool CanSelect { get; set; } public string MyProperty { get; set; } public override string ToString() { return this.MyProperty; } } 

这种方法唯一需要注意的是，如果ListBox具有单个选择，则尝试选择一个不可选择的项目将取消选择当前选定的项目，如果ListBox具有扩展选择，则取消选择all。

使用ItemsControl而不是ListBox
