You are designing an application by using Windows Presentation Foundation (WPF) and Microsoft .NET Framework 4.
You create a control named Help Viewer to view the Help documentation of the application.
The Help Viewer control must be available to all windows in the application.
You need to ensure that the application allows users to perform the following tasks:
- Bookmark their location in the documentation and return to the bookmark from any window
- Hide the Help Viewer control
- Dock the Help Viewer control
You create a main window as a base class.
What should you do next?
A. – Add the Help Viewer control to the window at runtime.
- Inherit all other window classes in the application from the main window base class.
B. – Add the Help Viewer control to a Dock Panel control at runtime.
- Inherit all other window classes in the application from the main window base class.
C. – Add the Help Viewer control and a Frame control to a Dock Panel control to the window at runtime.
- Create all other windows in the application as pages and host them in the Frame control.
D. – Add the Help Viewer control and a Frame control to a Stack Panel control to the window at runtime.
- Create all other windows in the application as pages and host them in the Frame control.
