Frame ControlTemplate Example

  • Artikel

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 Frame control.

Frame ControlTemplate Example

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