Activating XAML code during runtime

See more:

WPF

is there any method to incorporate XAML code segment into C# codebehind so that it will be executed at run time and will have the same effect based on certain events

ie something like this

private void button1_Click(object sender, RoutedEventArgs e)
       {
 some type of handling here

<TextBlock Text="{Binding ElementName=SampleText,
Path=Text}"
FontFamily="{Binding ElementName=FontList,
Path=SelectedItem}"
FontSize="32"
TextWrapping="Wrap" />

       }

thanks in advance
