WPF:列表框取消选择

Question

1. 当用户点击我的单选 ListBox 中的项目时，该项目被选中。
2. 当用户第二次点击某个项目时，除非他们按住 control 键，否则不会取消选择该项目。

将#2 更改为不需要控制键的推荐方法是什么？

Answer 1

确保选择模式是Multiple。通过选择多个:

you can use the mouse to select and deselect any item(s) you want with just a mouseclick. But if you want only 1 selected item at a time, you'll have to deselect the other items in code in the SelectionChanged event.

Source

Private Sub MainList_SelectionChanged(ByVal sender As System.Object, ByVal e As System.Windows.Controls.SelectionChangedEventArgs)
    If e.AddedItems.Count > 0 Then
        Dim valid = e.AddedItems(0)
        For Each item In New ArrayList(MainList.SelectedItems)
            If item IsNot valid Then MainList.SelectedItems.Remove(item)
        Next
    End If
End Sub
