Vista - Loading a XAML File Containing Controls

I have a XAML file that contains a few simple controls: stack panel,
text boxes, labels, etc.

I want to load this file into a separate XAML file (Window1.XAML) which
contains a tab control.

What are the steps involved? I tried defining the separate file as a
resource, but that didn't work (most likely because I did it
incorrectly).

I have been through the Petzold book, and various WPF sites, but can't
find an example of this.

Any help would be very much appreciated.

Thanks!

You can use Application.LoadComponent() to do the trick:
System.Uri resourceLocater = new System.Uri("window1.xaml",
System.UriKind.Relative);System.Windows.Application.LoadComponent(this,
resourceLocater);Sheva
