I've one listbox in which i got many events in every second these events are parsed by a metho. My problem is that i want to call that method but it always return empty string. and second listbox is filled with that null string. Another problem is that listbox is updated and parsed when the button is clicked but it didn't work. First time when i implement this works but all of sudden the things goes wrong.


Any help will be appreciated

If you made changes that made it go wrong then undo those changes and try again.
Otherwise, post some code so that we can see what you are doing!
