CheckBox.Checked Property

A logical value representing the current state of a check box. It is TRUE if the box is checked (or for 3-state check boxes, if it is in the third UNDETERMINED state), otherwise it is FALSE. The CheckBox:Checked assign also changes CheckBox:Value and CheckBox:TextValue. Also, if the CheckBox:Value is changed, CheckBox:ValueChanged is set to TRUE.
