No Insert Adorner for ListBoxDragDropBehavior?

[Larry]

I don't see any insert adorner support in ListBoxDragDropBehavior. (or at least it is not something can be done as simple as  ScreenshotDragVisualProvider). Being able to tell where to drop visually is extremely important to our application. If someone shed some light on this area I will be appreciated.

Hello Laijun Xie,

We are currently developing such functionality which is available in the our Latest Internal Build. I am attaching a simple project showing how this can be achieve. Please note, that due to a known bug currently in WPF the LinearDropVisualProvider is not shown, but you can see how it should behave in the Silverlight project. The behavior should be good to go for our next major release.

Thanks I upgraded to latest q2 dll and LinearDropVisualProvider does show up, however it does nothing in wpf as you explained.

Now I am curious why this has to be hold back by a bug as it seems quite straightforward and I can find quite a few implementations on internet. e.g. here: http://www.zagstudio.com/blog/488?

Hi Laijun Xie,

I am sorry for the misunderstanding.
When I said the next major release I meant  the Q3 2012, which is available for download from our website. Attached you can find a simple video showing how the Listbox behaves using LinearDropVisualProvider and ScreenshotDragVisualProvider. Also you can observe it in the Listboxs Drag and Drop example here in our demos.

Kind regards,
