Custom TabPage/TabItem

[UWGRAD]

Hello,

I have a TabControl on my main window and I would like it to have two types of tabs. One tab will have several textboxes on them. How do I create a general Tab Page. i.e. create an XAML file to go with my tab:

Public Class MyTab : Inherits TabItem
  CustomText_TextChanged(...)
End Class

Public Class CustomText : Inherits TextBox
End Class

<Resource>
  <Type:MyTab>
     <CustomText Name="CT1"/>
     <CustomText Name="CT2"/>
  </Type:MyTab>
</Resource>

<MainTabControl>
  <MyTab Header="Custom Tab" />
</MainTabControl>

I am really bad at XAML, so the XAML part will have to be explained.
