CheckBox Control

This CheckBox_control is a two-state check box. To associate an integer or string property with this control, enter the property name into the Property column of the Control table. The selected state of the box sets the property either to the value specified in the Value column of the CheckBox table or to the initial value of the property specified in the Property table. If the property has no initial value, the checked state sets it to 1. The unselected state sets the property to null.

CheckBox controls can only be used to publish AddLocal ControlEvent, AddSource ControlEvent, Remove ControlEvent, DoAction ControlEvent, or SetProperty ControlEvent controls.
