CheckBox component
Let a user toggle between two choices of a logical value. Or choose a number of options that are not mutually exclusive. Check boxes often are arranged in groups to present choices or options a user can turn on or off. Check boxes function independently of one another. RadioButtons, on the other hand, operate as a group; that is, when one is selected, all others in the group are unselected.
To link a check box,
Click the tool button beside the CheckBox's dataLink property.
In the Choose Fields dialog box, select a field to connect to the CheckBox control, or enter an expression in the text box next to the dataLink property, such as:
parent.query1.rowset.fields["CREDIT_OK"]
When you complete the link, the field value in the current record (true or false) appears in the check box.
