Tip of the Day: Manually Trigger Required Value Checks on Form Fields
Product.......: R:BASE X.5 and R:BASE X.5 Enterprise (Version 10.5)
Build.........: 10.5.5.11013 or higher
Sections......: Forms
Keywords......: Check Required Value, GETPROPERTY, Field, On Close
Did you know that, in addition to the right click context menu option,
the GETPROPERTY command has been enhanced at the form level to trigger
required value checks manually upon form fields?
The "Check Required Value" feature checks if a field has a value (not
empty), and displays an error message or warning if the required value
is not present. In the Form Designer, there are "required value" options
that may be defined for database and variable controls within the right
click context menu options. When enabled, a value for the field is
checked when the form is closed.
. Check Required Value on Form Close - specifies the control is checked
if it has a value in the form's "On Close" event
. Required Value Error Message - specifies the message if a value does
not exist for the control
In the event that the field is left empty, and the form is closed, the
defined error message will appear.
With the GETPROPERTY command, an EEP may be defined as below, to
manually trigger the required value check on the field, and close the
form if values are present:
GETPROPERTY RBASE_FORM CheckRequiredValues 'vState'
IF vState = 'OK' THEN
SAVEROW
CLOSEWINDOW
ENDIF
If the required value is intended to be a warning, and also for easier
development of several fields within a form, the below application
property was introduced to display a warning dialog, with an "Ignore"
button.
PROPERTY APPLICATION STRICT_VALUE_REQUIREMENTS ON
The default value is ON. When ON, the error dialog displayed. When OFF,
the warning dialog is displayed.
