<TextBlock Visibility="{Binding Text, Converter={StaticResource StringToVisibilityConverter}}" />

public class StringToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        string strValue = value as string;
        return string.IsNullOrEmpty(strValue) ? Visibility.Collapsed : Visibility.Visible;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
