Please, help me:
If I have a TextBox in a HubSection, how I can get data from it if the Grid that I have the TextBox is in a DataTemplate?,
<Hub Style="{StaticResource HubStyle1}">
    <Hub.Header>
    <!-- Some stuff here -->
    </Hub.Header>
    <HubSection Width="731" Style="{StaticResource HubSectionStyle1}">
       <DataTemplate>
           <Grid  FlowDirection="RightToLeft" Margin=" 0,10,0,0" >
               <TextBox  
                   Grid.Row="0" 
                   Grid.Column="1"     
                   Style="{StaticResource AddTextBlockStyle}"    />
           </Grid>
       </DataTemplate>
    </HubSection>
</Hub>
