Drag and drop move not working

[Michel Jost]

Hi,

we use a treeview with databinding to hierarchical data with a depth of n. Everything is displayed perfectly fine but the drag and drop behavior seems to be buggy.

AllowDragDrop is set to true and DragDropEffect is set to MoveOnly. When I drag a child and drop it on a different node, most of the time it is moved correctly but sometimes it seems to be copied to the new node. So the copied child seems to stay under the old parent node and a copy is placed under the new parent node. The copied child under the old parent can not be dragged again. 

We currently use the version 18.1.0.52.

Could be please try to reproduce this error and provide us a fix? 

Thanks in advance! 

Edit: copied child can be dragged again
