Drag & Drop in a treeGrid

[palgaz]

Hi,
Please is there anyway to get the source parent and the destination parent on dropping an object into a new destination ?
Thank you,

And also I have an other question, it's possible to do somes controles on dropping an object. For exemple check if the object is intanceof a SubType, if yes, then drop, else cancel the drop event
