I have code which handling tree of data elements in TreeView and I wanted to rewrite it for TreeListView.
I've stumbled upon lack of DragEnded event and DropPosition in the args of PreviewDragEnded event is not set correctly.
When I'm trying to drag item before (after) some element, DropPosition is set to Inside and this is not right.
How can be handled these inconsistencies?

Hi,
The DropPosition is determined from the relative mouse position during the drag operation, which is sometimes not always entirely correct. This is one of the reasons why we started implementing a new drag and drop mechanism (I have already mentioned it in your other thread).
You can use its GetPosition method, in the DragEventArgs in i. e. the DragOver event, to get a correct relative mouse position and determine the exact drop position of the dragged item.
Hope this helps!
