I cannot get the DropDownHeight of the ComboBox set properly to display all the items. I am using a control that inherits from the ComboBox.

In this Autofac IoC article they show an example of mapping an interface to an implementation with a parameter. You'll find it halfway down the article. What is the Unity equivalent in XML?
