As I said in title, I need to close the button interacted stackpanel item when close button is pressed. But I'm new in wpf and can't understand how to bind stackpanel or button with specific stackpanel item. Can you please help me ?

As you see I have a button and dynamically created stackpanels. How can I delete the stackpanel that it's button is clicked ?

I tried to delete stackpanel which is under it's delete button but every stackpanel is deleted in my code. I don't know how to specify which stackpanel will deleted when that stackpanel's close button is pressed

Code behind for what i tried is this

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);
            }

        }
    }

I solved this by adding checkbox to stack panel

<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>

and this code in model view

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();
    }
}
