Extended Drag and Drop Behavior
I decided to play around and make a new drag and drop behavior. I wanted one that would allow me to specify (in XAML or the Misc. bucket of the Properties panel in Blend) if the object would fade out, and how much or shrink or grow when dragged. So, I made one called ExtendedDragDropBehavior. You can download the sample HERE or see it in action HERE. You can add a reference or just copy ExtendedDragDropBehavior.cs to your project. Just make sure that your project has a reference to System.Windows.Interactivity.
Again, here is the link: windowspresentationfoundation.com/Downloads/DragDropBehaviorSample.zip
I will post a tutorial on how I made it soon.
PS: David Kelly will be presenting this behavior on Geekspeak soon. Stay tuned for details.
UPDATE: Andrew Whiddett has suggested some changes that make this a much better Drag/Drop Behavior. The new improved version can be found here: http://windowspresentationfoundation.com/Downloads/ExtendedDragDropBehavior.cs
