Binding XAML to codebehind in WPF
===

I have this textblock:

    <TextBlock x:Name="Coordinates" Text="Some Coordinates"/>

How can I access this object from the codebehind? I'm trying to replace the hardcoded coordinates in Locaton(), with the content of "Text":

    private void DestinationButton_Click(object sender, RoutedEventArgs e)
    {
        Location loc= new Location (20.2127297,-87.4625591);
        myMap.Center = loc;
        myMap.ZoomLevel = 8;
    }
