如何关闭窗口和按钮？

Question

我的这个窗口有一个“关闭”按钮。

当我按下“关闭”按钮时，它只会隐藏蓝色窗口，而不会隐藏图像中的 2 个按钮。

我希望它隐藏一切。我已经附上了这两个类的 C# 代码以及所有按钮的 XAML 代码。

  <local:KinectHoverButton Grid.Column="0" x:Name="leftbtn" Style="{StaticResource KinectHoverButtonScrollLeftStyle}" Click="PageLeftButtonClick" IsEnabled="{Binding ElementName=ControlsBasicsWindow, Path=PageLeftEnabled}"/>
  <local:KinectHoverButton Grid.Column="2" x:Name="right_btn" Style="{StaticResource KinectHoverButtonScrollRightStyle}" Click="PageRightButtonClick" IsEnabled="{Binding ElementName=ControlsBasicsWindow, Path=PageRightEnabled}"/>

隐藏按钮的方法：

public partial class ImagesGrid : UserControl
{
    public ImagesGrid()
    {
        InitializeComponent();
        leftbtn.Visibility = System.Windows.Visibility.Hidden;
        right_btn.Visibility = System.Windows.Visibility.Hidden;
    }
    public  void btn()
    {
        leftbtn.Visibility = System.Windows.Visibility.Hidden;
        right_btn.Visibility = System.Windows.Visibility.Hidden;
    }
}

隐藏SelectionDisplay窗口的方法和btn方法的调用

private void OnCloseFullImage(object sender, RoutedEventArgs e)
{
    // Always go to normal state before a transition
    this.Visibility = System.Windows.Visibility.Hidden;
    ImagesGrid img = new ImagesGrid();
    img.btn();
}

我想让按钮可见的地方

else if (button.Tag is WineModel)
{
    var wineModel = button.Tag as WineModel;
    var selectionDisplay = new SelectionDisplay(wineModel);
    this.kinectRegionGrid.Children.Add(selectionDisplay);
    leftbtn.Visibility = System.Windows.Visibility.Visible;
    right_btn.Visibility = System.Windows.Visibility.Visible;
    e.Handled = true;
}

编辑：SelectionDisplay.xaml

Answer 1

这段代码（来自关闭处理程序）

ImagesGrid img = new ImagesGrid();
img.btn();

创建一个全新的“ImagesGrid”，然后指示它隐藏。您需要获取对现有“ImagesGrid”的引用并在其上调用btn 方法。

由于它们绑定在一起，我会将“滚动”按钮作为包含“关闭”按钮的同一用户控件的一部分，并完全避免该问题。如果您真的想传递参考：

如果您的主用户控件具有“ImagesGrid”

<local:ImagesGrid Name="ScrollButtons"/>

然后你会写：

ScrollButtons.btn();

当然，这会导致问题，因为您的其他用户控件可能无法访问“ScrollButtons”，因此您需要在创建“ main" 用户控件等。它变得非常混乱，这就是为什么我将两者结合起来！
