The Enabled property of a data control determines whether it responds to mouse, keyboard, or timer events, and passes information to its data source. The default setting for this property is True. 

To prevent mouse, keyboard, or timer events from reaching a data control, set its Enabled property to False. When Enabled is False, the data source that connects the control to its dataset does not receive information from the data control. The data control continues to display data, but the text displayed in the control is dimmed.
