As a test, try changing your Items property on the DataTable to 'Table2'. Does it display any data?
If it does, then chage it back to your collection and add a Label to your screen with the Text Property of that Label set to : CountRows(Coleção1)
That lable should show 1 when you click on your button...what does it show and what is the result of the first test?
