Workflow Overview
You use the following workflow to create the relationship and add the properties to the blueprint.
1 Create the parent and child property definitions.
2 Add a Relationship attribute to the child property whose value is the name of the parent property.
3 Create a value expression that describes which values to display in the child drop-down list for each
value of the parent property.
4 Add the value expression as an attribute of the child property.
5 Add both properties to a blueprint or property group.
The following example is a logical progression from the following topics.
n
Add a Property Definition
n
Add a Relationship Attribute
n
Add a Value List Attribute
n
Add a Value Expression Attribute
Instead of specifying a ValueList attribute for the child property, you can use an XML string in a
ValueExpression attribute to specify the mapping between the values of the parent property and the
possible values of the child property.
This example uses the ValueList, ValueExpression, and Relationship property attributes with the
DropDownList property definition control type.
