Bind элемент дочернего объекта XAML

Question

первый код:

MyStyle.xaml

<Style x:Key="MyStyle" TargetType="Button"> 
    <Setter Property="ContentTemplate"> 
     <Setter.Value> 
      <DataTemplate> 
       <Grid> 
        <TextBlock x:Name="MyTextGen" Text="Foo"/> 
       </Grid> 
      </DataTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

MyUserControl.xaml

<UserControl x:Name="Mycontrol"> 
    <Grid> 
     <Button x:Name="Btn1" Style="{StaticResource MyStyle}"/> 
     <Button x:Name="Btn2" Style="{StaticResource MyStyle}"/> 
    </Grid> 
</UserControl> 

MyPage.xaml

<common:MainPage x:Name="MainPage"> 
    <Grid> 
     <Popup x:Name="CatTool" IsOpen="False" HorizontalAlignment="Center" VerticalAlignment="Center" 
       Margin="0 0 300 500"> 
      <cat:MyControl > 
       <cat:MyContro.Transitions> 
        <TransitionCollection> 
         <PopupThemeTransition/> 
        </TransitionCollection> 
       </cat:MyContro.Transitions> 
      </cat:CatPagecontrol> 
     </Popup> 
    </Grid> 
</common:MainPage> 

Info.cs

MyDict = new Dictionary<string, string> 
{ 
    {"First", "MyFirst"}, 
    {"Second", "MySecond")} 
}; 

Я хотел бы связать MyDict "первый" и "второй" в MyTextGen по MainPage, возможно ли это?
