我可以通过拖动行项目而不是滚动条来滚动ItemsControl [英] Can i scroll an ItemsControl by dragging row items instead of scrollbar

问题描述

我想知道如何通过单击一个项目并上下拖动鼠标来上下滚动像ItemsControl这样的列表容器，而不是使用ScrollViewer在滚动条上拖动吗?

Im wondering how i would go about scrolling a list container like ItemsControl up and down by clicking on an item and dragging your mouse up or down, instead of using dragging on a scrollbar using ScrollViewer?

我在Google周围搜索，但是使用滚动条上下滚动项目列表只能找到结果.

I have googled around but found only results using a scrollbar to scroll up and down a list of items.

您可以使用某人写的以下附加行为:

用法如下:
