Drag-drop between table and tree

I want to drag and drop and element between a table and a tree. It’s mostly working, but I would like to override the creation of the element in the tree . Basically I don’t want to create an element at all since I’m dropping a file into a folder. I have my events set up for onBeforeDrag and on onBeforeDrop, and that work. I looked at ‘externalData’ on the tree but doesn’t seem to be the right place. Can I get an event for the actual drop ?
thanks

It seems that onBeforeDrop is a correct event. You can return false from the event handler and an item won’t be dropped.

Yes that what I ended up doing.
thanks.
