WPF:列表框，将所选项目居中 [英] WPF: Listbox, centering selected item

问题描述

是否可以始终将所选项目保留在列表框的中间?如果用户选择了一个项目，则我要滚动以便新选择的项目位于中间.

Is it possible to always keep selected item in the middle of a listbox? If the user selects an item, I want to scroll so that the newly selected item is in the middle.

我想这可能是边缘情况"(前几项和最后几项)的可能，但是没关系.

I guess it want be possible for the 'edge cases' (the first and last few items), but that's ok.
