TabItem in a separate XAML

Question

Is it possible to put a TabItem into a separate XAML and reference something like this:

Answer 1

I think what you wanted is to get TabItem Content declare separately. Since TabItem is a ContentControl you can present a UserControl as its content.

In Separate XAML:

  <......blah blah.../>

In another XAML you can have content 2

   <......blah blah.../>
