Syntax

public class RequiredForPersistenceAttribute : RequiredAttribute

Remarks

There are two levels of validation in Umbraco. (1) value validation is performed by IValueValidator instances; it can prevent a content item from being published, but not from being saved. (2) required validation of properties marked with RequiredForPersistenceAttribute; it does prevent an object from being saved and is used for properties that are absolutely mandatory, such as the name of a content item.
