    Hi,

    The SelectionChanged event of RadCarousel works only when the Non-Top item is selected. Is there a event/way to know when the user clicks on the Top item? Currently I'm using the DoubleClicked event to check for the Top item's property, to identify it. But, I want to know whether I can handle it with a single click.

    Thanks in advance.

    Hello Ela,

    What you can do in this case is to AddHandler and handle the PreviewMouseLeftButtonUp event. For example:

    public partial class MainWindow : Window
    {
      public MainWindow()
      {
        InitializeComponent();
        this.MyCarousel.ItemsSource = new ObservableCollection<int>() { 1, 2, 3, 4, 5 };
     
     
        this.MyCarousel.PreviewMouseLeftButtonUp += new MouseButtonEventHandler(MyCarousel_PreviewMouseLeftButtonUp);
        this.AddHandler(RadCarousel.MouseLeftButtonUpEvent, new MouseButtonEventHandler(MyCarousel_PreviewMouseLeftButtonUp));
       }
     
    void MyCarousel_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
    {
        UIElement source = e.OriginalSource as UIElement;
     
        var carouselItem = source.ParentOfType<CarouselItem>();
        if (carouselItem != null && carouselItem == this.MyCarousel.FindCarouselPanel().TopContainer)
        {
            MessageBox.Show("Clicked is Top Item");
        }
      }
    }

     
    Thus in this case when the top item is clicked a message will be shown. However, you can apply whatever logic you need.
