在 wpf 中，当我按下按钮时，它会关闭所有堆栈面板。按下按钮时我需要关闭特定的堆栈面板

Question

正如我在标题中所说，我需要在按下关闭按钮时关闭按钮交互的堆栈面板项目。但我是 wpf 的新手，无法理解如何将堆栈面板或按钮与特定的堆栈面板项目绑定。你能帮帮我吗？

如您所见，我有一个按钮和动态创建的堆栈面板。如何删除单击按钮的堆栈面板？

我试图删除位于其删除按钮下方的堆栈面板，但我的代码中的每个堆栈面板都被删除了。我不知道如何指定在按下堆栈面板的关闭按钮时删除哪个堆栈面板

我试过的代码是这个

public IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
    {
        if (depObj != null)
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild(depObj, i);

                if (child != null && child is T)
                    yield return (T)child;

                foreach (T childOfChild in FindVisualChildren<T>(child))
                    yield return childOfChild;
            }
        }
    }

    private void fixButton_Click(object sender, RoutedEventArgs e)
    {
        string tooltip = "";
        List<string> ttlist = new List<string>();
        foreach (var textblock in FindVisualChildren<TextBlock>(this))
        {
            if (textblock.Name == "fixText")
            {
                tooltip = textblock.Text;
                ttlist.Add(tooltip);
            }
            break;
        }

        for (int i = 0; i < RealTimeMapDataGeneratorModel.sb.Count; i++)
        {
            System.Console.WriteLine(tooltip);
            System.Console.WriteLine(RealTimeMapDataGeneratorModel.sb[i].ToolTipText);
            if (ttlist[i] == RealTimeMapDataGeneratorModel.sb[i].ToolTipText)
            {
                //SubmarineVectorLayer.Visibility = Visibility.Hidden;
                RealTimeMapDataGeneratorModel.Submarine.RemoveAt(i);
                RealTimeMapDataGeneratorModel.sb.RemoveAt(i);
            }

        }
    }

我通过在堆栈面板中添加复选框解决了这个问题

<Border BorderThickness="1" CornerRadius="10" Opacity="1.0" Background="{dxi:ThemeResource {dxmt:MapBrushesThemeKey ResourceKey=OverlayBackground}}">
   <StackPanel Orientation="Vertical" Margin="8">
       <CheckBox x:Name="MyCheckBox" IsChecked="True" HorizontalAlignment="Left"/>
       <TextBlock Text="{Binding ToolTipText}" Visibility="{Binding IsChecked, ElementName=MyCheckBox, Converter={dxmvvm:BooleanToVisibilityConverter}}" Foreground="{dxi:ThemeResource {dxmt:MapBrushesThemeKey ResourceKey=OverlayElementForeground}}"  TextWrapping="Wrap"/>
   </StackPanel>
</Border>

模型视图中的这段代码

public class BoolToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var isChecked = (bool)value;
        return isChecked ? Visibility.Visible : Visibility.Collapsed;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
