Hi, I'm interested in the same functionality, where I'd like to drag from one arbitrary control into a tilelist, and have the tilelist's tiles re-order as I'm dragging in the new content, indicating where the drop would occur.
I looked through the documentation, but it's very limited and vague. Can you please provide a more concrete example specific to tilelist, or explain what needs to be done to do this to work?
Does a custom DragDropBehavior need to be written for this?
How will adding such behavior interact with the tilelist's own drag/drop functionality?
