Assign Property Values

Property assignments assign specific values to properties under certain events and conditions. Property assignments are useful in numerous situations including:

• Setting default values for new documents
• Calculating a property value based upon the values of other properties
• Recalculating one value when the value of another property changes

To assign property values:

1. In Configurator, expand Property Sets in the configuration tree to display the existing property sets.
2. Expand the property set that contains the property for which you want to configure assignments. The names of the properties currently in the selected property set appear.

3. Select the desired property in the configuration tree. The property’s property pages appear in the right pane.

   Note:

   The Enable for scripting option must be selected and VBScript name must be complete for the Validation and Assignment pages to be active.

4. Click the Assignment tab. The property’s existing assignments appear.
5. Click the Edit button to edit the property.
6. If you want to modify an existing assignment, select it in the list of assignments. The assignment’s settings appear at the bottom of the page.
7. If you want to create a new assignment, click the Add button to add a new assignment to the list of property assignments.

8. Select an event from the When column using the descriptions in the following table.

   Note:

   Property change events occur in the order listed in the previous table. If multiple assignments are configured for a property, depending on the options selected for Condition and Assignment, you may want to arrange them in step 12 to be applied in the same order.
