WPF：通过拖放重新排序WrapPanel内容？ [英] WPF : Reorder WrapPanel content via drag and drop?

问题描述

我正在寻找一种通过拖放方式重新排序WPF WrapPanel的内容（项目）的方法。我只想点击一个项目并将其拖动到一个新的位置。

I am looking for a way to reorder the content (items) of a WPF WrapPanel via drag and drop. I just want to click on an item and drag it to a new position.

据我了解，这是一个非常常见的任务，我想知道有人已经这样做了任何想法如何实现这个功能。

To my understanding this is a very common task and I wonder I someone already did this or has any idea how to implement this functionality.

我已经做了谷歌搜索，但没有发现任何东西。也许比我预想的要困难。

I did a google search already but found nothing. Maybe it is more difficult than I expected.

推荐答案

我写了一个可能有帮助的库：默认行为是允许重新在同一控制范围内：

I've written a library which may help: default behaviour is to allow re-ordering within the same control:

啊我注意到你只是在说一个WrapPanel ：您需要使用带有WrapPanel的ItemsControl：

Ah I notice you're talking about just a WrapPanel: you'll need to use an ItemsControl with a WrapPanel:

<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
        <WrapPanel />
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
