Hi Adria,
In Treeview, you can disable the AutoExpand mode while performing the DragAndDrop operation by setting the CanAutoExpand property to false in the TreeViewDragDropController. Please refer to the below code snippets.
public MainWindow()
{
InitializeComponent();
this.sfTreeView1.DragDropController.CanAutoExpand = false;
}
Let us know if you need any further assistance on this.
Regards,
Sathiyathanam
