How to serialize custom properties with a custom type using the CreateContentPropertyValue event

This example demonstrates how to serialize and deserialize custom properties with a custom type.

In the CreateContentPropertyValue event handler, create a new instance of a custom type and assign it to the XtraCreateContentPropertyValueEventArgs.PropertyValue property.
