从下到上显示 ListBox 项 [英] Present ListBox Items Bottom-to-Top

问题描述

我已经搜索了很长一段时间试图找到答案，但没有任何结果.

I've searched for quite a while trying to find an answer to this without any results.

默认的 WPF 列表框添加在顶部对齐的项目，并在其下方添加其他项目.我想要一个以相反方向显示项目的列表框，因此它会添加与底部对齐的项目.

The default WPF Listbox adds items aligned at the top, and additional items below it. I'd like a listbox which presents the items in the opposite direction, so it adds items aligned to the bottom.

示例:

我确信一定有一种更简单的方法，我忽略了它而不重写它，但谷歌似乎没有这个答案，我很难过.

I'm sure there must be a simpler way that I've overlooked to do this without rewriting it all, but Google doesn't seem to have the answer for this one and I'm stumped.

谢谢.

推荐答案

改变ItemsPanel的布局:

<ListBox.ItemsPanel>
    <ItemsPanelTemplate>
        <VirtualizingStackPanel VerticalAlignment="Bottom"/>
    </ItemsPanelTemplate>
</ListBox.ItemsPanel>

这与您的图像似乎暗示的一样，添加的第一项仍位于顶部.如果您也想颠倒顺序，那将是一个不同的问题.

This does what your image seems to imply, with the first item added still on top. If you want to reverse the order as well that would be a different issue.
