show a page inside a window in XAML

Question

I have a tabcontrol in my window, inside each tabitem I want to have a different page.
I can achieve this by making a Frame inside the TabItem and in the behind code use for example:

frame1.Content = new Pages.MyPage()  

How can I do the same thing in XAML?

Solution

<TabItem>
  <Frame Source="MyPage.xaml" />
</TabItem>

The first solution results in an InvalidOperationException: "page can only have window or frame as a parent". The second one, "Frame does not support direct content".

Does MyPage extends UserControl? If not, which class does it extend?

[Steinthor.palsson]

I don't know. It's just a normal page. How would I know that?

[Steinthor.palsson]

hah... that simple. Thanks. It won't show up in the designer though. Maybe it's not possible?
