Drag and Drop/Reorder items in wrap panel?

I have a need to create an interaction in wrap panel to allow drag and drop functionality of items. I generate content in wrap panel dynamically with XMLDataprovider. I was not able to find any similar interaction online. 开发者_开发问答How can this be achieved?

Check out the work done by Martin Grayson. It is an open source project on CodePlex titled Blacklight. There should be both an SL version and WPF version doing what you need to do via the Drag Dock Panel, with source available to get a better understanding on how it is implemented.

To see the sample from above, click WPF then click Drag Dock Panel on the lower left.

EDIT: It appears that default WPF support was stripped in 4.3, however jump back to 4.2 and both the binaries and source have their respective WPF offerings.
