WPF : Reorder WrapPanel content via drag and drop?

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 v开发者_如何学JAVAery 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>

A wrap panel won't give you the functionality you are looking for since it is just for layout. Instead look at adding the drag and drop functionality to a ListBox and change the ItemsPanelTemplate of that ListBox to use a wrap panel.
