This property returns and sets a value that determines whether a form or control can respond to user-generated events.
object.Enabled [= Boolean]
The Enabled property allows forms and controls to be enabled or disabled at run time. For example, you can disable objects that do not apply to the current state of the application. You also can disable a control used solely for display purposes, such as a text box that provides read-only information.
Disabling a Timer control by setting Enabled to False cancels the countdown set by the control's Interval property.
