Hi, I have a single tree list which contains several top level nodes, each node has multiple children. What I want to do is to only allow movement of nodes within only within the list of sibling nodes.
The effect that I'm after is something similar to the first animation in https://stackoverflow.com/questions/45838579/separator-line-drag-drop-tree-nodes-c-sharp-winforms.
I have set my tree view AllowDragDrop to true and this allows me to move items around however it is possible to move an existing into a sibling node and generate a sub-tree.
Is this possible and if so, how ? Also is it possible to override the drawing of the "insertion point" ?
