WPF Content Model

The Windows Presentation Foundation (WPF) is a presentation platform that provides many control and control-like types whose primary purpose is to display content. The content models of these types can be very flexible, and at times, very rigid. For example, some types can contain only a single piece of content but some can contain multiple items. In addition, the content may be text, other controls, or a specific set of elements.

This topic organizes the control and control-like types based on the inheritance hierarchy and provides a quick reference for the content models of these type families. A content property is a property that is used to store the content of the object. This topic includes only types distributed with the Windows SDK.

For content model information for a specific type family, see the corresponding content model overview.

This topic contains the following sections.
