wpf - wpf 使用键盘[Ctrl + RightArrow/leftArrow] 选择多个 ListboxItems（即图像）

Question

我已经对列表框项目进行了分组，我可以通过 SelectionMode="Extended" 或 "Multiple" 选择 "Multiple" 项目。现在我在“排序”中有两个问题和一件事

1. 什么时候

[选择模式=“扩展”]

我可以通过按下并使用鼠标选择项目来选择多个项目，一旦我将鼠标移动到其他控件，我就会失去我的选择。

2.我无法使用键盘选择多个项目，也无法使用箭头键前往 listboxItems（即）“图像”。

1. 我想对分组的项目进行排序/排列。任何人都可以提前指导这些..thnx。
