NavigationWindow ControlTemplate Example

Controls in Windows Presentation Foundation (WPF) have a ControlTemplate that contains the visual tree of that control. You can change the structure and appearance of a control by modifying the ControlTemplate of that control. There is no way to replace only part of the visual tree of a control; to change the visual tree of a control you must set the Template property of the control to its new and complete ControlTemplate.

This topic shows the ControlTemplate of the WPF NavigationWindow control.

This topic contains the following sections.

To run the examples in this topic, you should understand how to write WPF applications. For more information, see Getting Started with Windows Presentation Foundation. You should also understand how styles are used in WPF. For more information, see Styling and Templating.

Although this example contains all of the elements that are defined in the ControlTemplate of a NavigationWindow by default, the specific values should be thought of as examples.
