It can be helpful to assign a status to each item in the list. This way, when you walk in the supermarket, you can mark the items you have already bought.
Adding a field is easy using the 'Table Wizard':
The wizard will update your model with the additional field in all relevant places. If you now save your model, stop the application and then restart it, you will be able to update the status of any item you choose.
Updating an item's status requires the selection of its row in the table, pressing the 'Update' button, entering the new status, and pressing 'Save'.
Walking in the supermarket with your iPhone, you may prefer a one-click method to mark the items you have already bought. To support this, we can add a 'Got It' button to mark an item as bought:
The straightforward way is to create the 'Got It' button in the 'Action Header Group' of the row above the item table (the group with the existing buttons 'New', 'Update' and 'Delete'):
If you now restart the application, you will only need to select a row and press 'Got It', and its status will be changed to √.

We would like to make 'Got It' a one-click-button (save the need to select a row before pressing the button).
This can be achieved by putting a 'Got It' button in each row – clicking the button will change the status of its row.
Modeling is trivial:
Note that 'Got It' works both ways – either selecting a row and then pressing the 'Got It' that appears above the table, or pressing a 'Got It' in one of the rows. This is possible because of the way 'Got It' is modeled (referring to the selected table row).
Once an item is marked as bought (√), we no longer need the 'Got It' button in its row.
Actually, if we only display the buttons for the other items, we will make it easier to see which items we still need to look for on the shelves.
We can model this by displaying the 'Got It' button only if the item's status is different from '√':
If you now restart the application you will notice that when you press 'Got It', the item's status is changed, and the 'Got It' button disappears:

To save some space on the screen, we can embed the 'Got It' button in the 'Status' field of each row:
This is what you get if you now restart the application:
