You apply the DisplayColumnAttribute attribute to an entity class to specify the behavior for a class with a foreign key relationship to another class. You apply this attribute to the class that acts as the parent in the foreign key relationship. You can specify the property to use for displaying the foreign key relationship, the property to use for sorting, and the sort order. The properties you specify are properties within the parent class, not the related class.
