                >


            <TextBlock x:Name="textBlock1"
                       Height="{Binding Height}" 
                       FontSize="50"
                       TextWrapping="NoWrap" 
                       Foreground="{Binding Foreground}"
                       Text="AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"
