getting selected row from the database table

I have created an inventory control system where I have given a list option. This option when clicked gives me the details of the items in the database.Now when I click on one particular item it should show me the details of that particular item only but in my program whenever I click on any of the item it shows me the details of the last item only.
Your guidance would be of great help.
