i don't know your project but sometimes data aren't populated till they need to be shown (and it's not a TC problem but coding optimization for faster load).
So you can use the following trick; select your treeview, and use arrows to navigate until accessing the desired item and thus it is displayed and therefore can be accessed.
- Call treeViewObj.SelectItem( 0 , 0)
- Key down until the desired row index
- Call treeViewObj.Clicktem( rowIndex , 0)
BTW this is more the reality because an user cannot click on invisible item so for testing it's better.
