- The month is between 1 and 12 (or 0-11 for
Dateobjects) - The day is between 1 and 31
- The year is a number
You can specify the date in the DateValidator class in two ways:
- Single String containing the date - Use the
sourceandpropertyproperties to specify the String. The String can contain digits and the formatting characters specified by theallowedFormatCharsproperty, which include the "/\-. " characters. By default, the input format of the date in a String field is "MM/DD/YYYY" where "MM" is the month, "DD" is the day, and "YYYY" is the year. You can use theinputFormatproperty to specify a different format. -
Dateobject. - Object or multiple fields containing the day, month, and year.
Use all of the following properties to specify the day, month,
and year inputs:
daySource,dayProperty,monthSource,monthProperty,yearSource, andyearProperty.
