Question: I have a Window where I have put a Frame. I would like to add a Page to the Frame when I click a button that is also on the Window but not in the Frame. There are several buttons in the Window and each click on a button should load a different Page in the Frame.

Since I'm a total newbie on this WPF stuff it's quite possible that this approach is not the best and I have thought about replacing the Frame with a Canvas and then make UserControls instead of Pages that will be added to the Canvas. I welcome any ideas and suggestions on how to best solve this. 

I aiming for a functionality that is similar to the application Billy Hollis demonstrated in dnrtv episode 115. (<http://dnrtv.com/default.aspx?showID=115>).

Answer: 
the Frame class exposes a method named "Navigate" that takes the content you want to show in your frame as parameter.
try calling 

```
myFrame.Navigate(myPageObject);

```

this should work
yourFramName.NavigationService.Navigate(yourPageObject)

e.g 
Frame1.NavigationService.Navigate(new Page1());
