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.
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.
I did a google search already but found nothing. Maybe it is more difficult than I expected.
I've written a library which may help: default behaviour is to allow re-ordering within the same control:

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>
