RichText Input Field property sheet: Validation tab
Description
Change the validation rule that applies to the selected column
in the current DataWindow object.
Validation rules are expressions that PowerBuilder uses to
validate user-entered data. If a validation rule is defined for
a column in the Database painter, it becomes the default validation
rule for the column and is stored in the database repository. Changing
the validation expression for a DataWindow object does not change
the rule in the repository.
Options
Validation expression
Enter or paint the definition of the validation criteria to
be applied to a value entered in the column. If the column has a
validation rule associated with it in the database, that rule is
assigned to the column by default. Click the Verify button to test
the expression.
Operators
Select an operator to paste it into the expression at the
cursor.
Functions
Select a function to paste it into the expression. The argument
is selected so that you can replace it with a column name.
Columns
Select a column to paste it into the expression at the cursor.

Error message expression
Enter a customized message for validation failure (optional).
