Just incase anyone ever has an issue similar to this. I have no idea why but not manually coding the NTreeListNodeStringSubItem Column to link to a specific column in-code will cause this symptom. Setting the column manually fixes it and the data will not get lost when drawing over the control or resizing it. Strange issue. Simple fix.

DataNode.Column = lvwColumn1

Whenever a control draws ontop of an active NListView it seems to loose the item column and header. When I load another control ontop of and then close it the items in the first column appear as they should. I have tried to manually refresh the control no luck. I'm drawing blanks how to fix this.

Any ideas?
