When do you think the update is occurring? Is it when your bound control loses focus? I created a simple test project with a textbox, button, and datacontrol. I linked the datacontrol to an access database and bound the textbox to a field in a test table. If I change the data in the textbox, the update will only occur when I change records (using the datacontrol), or execute the UpdateRecord method. Tabbing off the control does not cause an update.
