“清除”窗口为新用户控件腾出空间？

Question

I'm usually working with Windows Forms Applications, but I'm currently needing Windows Presentation Foundation for design purposes.

What I am needing to do is clear out the current open window and fill it with new user controls as though a new window has been opened. In short, open a new window without actually opening a new window, similar to navigating to a new page in a web browser. (Still the same window open in the Taskbar, no extras.)

I was unsure if there was a specific class or control that made this easy to do. If someone could enlighten me on the way to do this in WPF, I would be very pleased.

Thanks.

There are a number of possible ways - here are a few that come to mind:

Navigation

In WPF, you can actually navigate to different xaml pages. In this scenario, you would define a number of pages that a main page could navigate to.

Programmatic

You can do it the old school way and just clear out all of the controls in a window. For example (in the context of a window):

StackPanel stackPanel = new StackPanel();

stackPanel.Children.Add(new MyUserControl1());
stackPanel.Children.Add(new MyUserControl2());

this.Content = stackPanel;
