#169 – The Base Element Classes

There are four main classes that that serve as base classes for many of the other classes in WPF.  They also often serve as base classes for new custom classes that you write.

The four base element classes are:

  • ContentElement
  • FrameworkContentElement
  • UIElement
  • FrameworkElement


#168 – A More Complete Class Hierarchy

Post #27 presented a class hierarchy that shows the most common classes used in WPF.  Here is an updated view, with ContentElement and FrameworkContentElement added.  These two classes are sometimes used as base classes for creating new elements, so it’s important to know where they fit in the class hierarchy.
