Maybe I am wrong at the beginning. If it can be done in one application, it should be easier. Now my question is, if I select one of the list item, I want to bring up a new view. Can anyone help on this. Thanks in advance
Basically you could implement the offer key function for your listbox container and handle EKeyDevice3 key there (middle button in arrow or OK button). Basically there you would call the function opening the new view/app.
You could also handle in menu options in your command handlers to call the same functio as well if needed.
Then in youir function you would check the selected item with listboxes CurrentItemIndex()-fucntion. (gives you index from zero to count()-1).
