When the delete icon is clicked in an item I want to get the selected item for deleting but I don't know how it should be done. Thanks in advance

您可以将您的项目插入 ObservableCollection，当项目被删除时可以通知 ui 界面。更多内容请参考以下

Xaml代码

<ListView ItemsSource="{x:Bind Items}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock
                    VerticalAlignment="Center"
                    FontSize="15"
                    Text="{Binding}" />
                <AppBarButton
                    Click="AppBarButton_Click"
                    Icon="Delete"
                    Label="Delete"
                    Visibility="Visible" />
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();
        for (int i = 0; i < 10; i++)
        {
            Items.Add($"items{i}");
        }
        
    }
    public ObservableCollection<string> Items { get; set; } = new ObservableCollection<string>();
    private void AppBarButton_Click(object sender, RoutedEventArgs e)
    {
        var item = (sender as AppBarButton).DataContext;
        Items.Remove((string)item);
    }
}
