How many items do you have in your ListView? Use the debugger and put a breakpoint at line 8 then compare your ListView items with the index. Also, get rid of the goto. If you must use a loop then use a structured loop.

listview contains 10 items but class don't see any items

It sounds like your listview is out of scope. It's impossible to tell based on the little code you provided. Why not just implement the code as a function rather than as a class since the listview is external to the class anyway?
