Data Consumers

I have created a data source and I have tried binding it to controls and to a data consumer. When I change the information on the control (i.e. Text1), the data source updates the database. However, when I try to change a property in the data consumer, it only updates the class local variable, and not the database.

Could someone please explain the process of updating fields in a database using a data source and data consumer.

Thanks,
