返回主窗口时的网格可见性

Question

我有一个主窗口，其中包含一个包含一些按钮的堆栈面板。对于每个按钮，我有一个相关的网格面板，而该网格面板又有几个图像按钮。单击网格面板图像按钮将打开一个新窗口。在主窗口中，我的网格可见性设置为隐藏（因为我希望仅在从堆栈面板中单击其中一个按钮时才显示网格）但是当我单击新窗口上的后退按钮时，我想要选择的网格可见。如何实现这一目标？我没有使用MVVM。

在选择Home选项时，它会显示grid_home。在grid_home上点击库存按钮，它会打开库存窗口：

  <Window x:Class="WpfApplication5.inventory"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Inventory" Height="300" Width="469.611">
<Grid Margin="0,0,2,0">
    <Button Content="Back" HorizontalAlignment="Left" Margin="195,223,0,0" VerticalAlignment="Top" Width="75" Height="37" Click="Button_Click_1"/>

主窗口代码隐藏的一部分：

   private void Button_Click_1(object sender, RoutedEventArgs e)
    {

        grid_home.Visibility = Visibility.Visible;
        grid_b.Visibility = Visibility.Collapsed;

    }

    private void Button_Click_8(object sender, RoutedEventArgs e)
    {
        inventory obj = new inventory();
        obj.Show();
        this.Close();

    }

库存窗口背后的部分代码：

     private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        Home_window obj = new Home_window();
        obj.Show();
        this.Close();
        grid_home.Visibility = Visibility.Visible;
    }
}

}
