在Metro Style App中从父框架访问源页面中的TextBlock控件

Question

My Source Page

<Grid>   
    <TextBlock x:Name="TbHeader"/>
    <Frame x:Name="FrmPages" d:IsLocked="True"/>
</Grid>

My Source Page Codes

  protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            FrmPages.Navigate(typeof(Categories));
        }

This my parent Categories page codes

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    //??? How can I change TbHeader.Text?
}

Thank you very much.

If I get your question correctly you are trying to change values in an XAML page that isn't being shown at the moment. If that's the case it doesn't really make sense.

If you would like to send data from a page to another depending on user input, you can use Navigate to send parameters, see this tutorial .
