VALUEUNCHECKED attribute
The VALUEUNCHECKED
attribute defines
the value associated with a checkbox item when it is not checked.
Syntax
VALUEUNCHECKED = value
- value is a numeric or string literal, or one
of the following keywords:
NULL
,TRUE
,FALSE
.
Usage
This attribute is used together with the VALUECHECKED
attribute to define the
values corresponding to the states of a CHECKBOX
.
This attribute is not used by the runtime system to validate the field. Use
the INCLUDE
attribute to
control value boundaries.
Important:
For maximum security, when the data is stored in a database, define a CHECK
constraint on the SQL column corresponding to the field, in order to allow only values matching the
VALUECHECKED
/ VALUEUNCHECKED
attributes, when an
INSERT
or UPDATE
statement is executed.
Example
CHECKBOX cb01 = FORMONLY.checkbox01,
TEXT="OK",
VALUECHECKED="Y",
VALUEUNCHECKED="N";
