TreeView - detect node position change

AL|EN

I have TreeView:

Group01
- PackageP1
- ComponentC1
- ComponentC2
Group02
- PackageP2
- ComponentC3
- ComponentC4
Group03
- PackageP3
- ComponentC5
- ComponentC6

The position of the nodes of this treeview can be changed via Drag&Drop, keyboard hotkey and separate Up/Down buttons. How to react when node will change it's position on the TreeView? I didn't find anything which might be Event OnNodeIndexChange.

Use the After Select Event or Before Select Event
You can use the treeview event args to detect what selected the node such as keyboard or mouse click.
