Expression

Note: This field is available only for Derived properties or Unbound properties. If the value in this field is inherited from a property class, this field is read-only. To edit the value, clear the Inherit from Property Class check box.

The value in this field can be used for either of these purposes:

  • For an Unbound property, this value is used as the initial value for the property.
  • For a Derived property, use this field to create an expression that is used to provide the value of the property.

    For more information about expressions used in derived expressions, see About expressions in derived properties.
