  7. Add the XAML namespace to the UserControl or Window tag with the following markup:
    xmlns:c1=http://schemas.componentone.com/winfx/2006/xaml
    

    The namespaces will now appear similar to the following:

    WPF XAML
    Copy Code
    <Window x:Class="MainWindow"                        
    
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                            
    
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                            
    
        xmlns:c1="http://schemas.componentone.com/winfx/2006/xaml"                            
    
        Title="MainWindow" Height="350" Width="525">
    

    Silverlight XAML
    Copy Code
    <UserControl x:Class="QuickStart.MainPage"                      
    
      xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation                            
    
      xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml                            
    
      xmlns:d=http://schemas.microsoft.com/expression/blend/2008                            
    
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"                              
    
      xmlns:c1="http://schemas.componentone.com/winfx/2006/xaml" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400">
    

  8. In the XAML view add a <Resources> tag just under the <UserControl> or <Window> tag and above the <Grid> tag with the following markup:

    WPF XAML
    Copy Code
    <Window.Resources>
    </Window.Resources>
    

    Silverlight XAML
    Copy Code
    <UserControl.Resources>   
    
    </UserControl.Resources>
    

    You will add templates within this tag.

  9. Add an ItemsPanelTemplate within the Resources tag to define the CarouselPanel:

    XAML
    Copy Code
    <ItemsPanelTemplate x:Key="carouselPanelTemplate">
    <c1:C1CarouselPanel Padding="0, 10, 50, 50" VerticalPathAlignment="Center" HorizontalItemAnchorOnPath="Center" VerticalItemAnchorOnPath="Center"/>
    </ItemsPanelTemplate>
    

  10. Insert a <DataTemplate> to define the image source:

    XAML
    Copy Code
    <DataTemplate x:Key="carouselItemTemplate">
    <Image Source="{Binding}" Stretch="None" />
    </DataTemplate>
    

  11. Add the following <Style> under the <DataTemplate> to set the PathGeometry property for the CarouselPanel control:

    XAML
    Copy Code
    <Style x:Key="parabolaPanelStyle" TargetType="ListBox">
    <Setter Property="c1:C1CarouselPanel.PathGeometry" Value="F1 M 164.564,73.0518C 201.647,164.183 238.73,255.315 284.817,323.23C 330.903,391.146 385.993,435.845 445.921,431.137C 505.849,426.43 570.614,372.315 614.53,304.361C 658.446,236.407 681.512,154.614 704.578,72.8207"/>
    <Setter Property="c1:C1CarouselPanel.HorizontalPathAlignment" Value="Left"/>
    <Setter Property="c1:C1CarouselPanel.VerticalPathAlignment" Value="Top"/>
    <Setter Property="c1:C1CarouselPanel.PerspectiveAngle" Value="90"/>
    <Setter Property="c1:C1CarouselPanel.PerspectiveFactor" Value="-0.317"/>
    </Style>
    

  12. Add the following ListBox control within the <Grid>:

    XAML
    Copy Code
    <ListBox Background="Transparent" Name="carouselListBox" Grid.Row="1" ItemsPanel="{StaticResource carouselPanelTemplate}"
    ItemTemplate="{StaticResource carouselItemTemplate}" Style="{StaticResource parabolaPanelStyle}"/>
    
  13. Right-click the MainPage.xaml page and select View Code from the list.
  14. Add the following namespaces to the top of the page:

    WPF
    Copy Code
    Visual Basic:
    Imports System.Windows.Media.Imaging;
    Imports C1.WPF;
    Imports C1.WPF.Carousel;
    
    C#:
    using System.Windows.Media.Imaging;
    using C1.WPF;
    using C1.WPF.Carousel;
    

    Silverlight
    Copy Code
    Visual Basic:
    Imports System.Windows.Media.Imaging
    Imports C1.Silverlight
    Imports C1.Silverlight.Carousel
    
    C#:
    using System.Windows.Media.Imaging;
    using C1.Silverlight;
    using C1.Silverlight.Carousel;
    

  15. Insert the following method directly below the InitializeComponent() method:

    Visual Basic
    Copy Code
    InitData()
    

    C#
    Copy Code
    InitData();
    

  16. Call the following method to populate the CarouselPanel with data:

    Visual Basic
    Copy Code
    Private Sub InitData()
       For i As Integer = 101 To 140
             carouselListBox.Items.Add(New BitmapImage(Extensions.GetAbsoluteUri("Resources/covers/cover" & i & ".jpg")))
       Next
    End Sub
    

    C#
    Copy Code
    private void InitData()
          {
              for (int i = 101; i <= 140; ++i)
              {
                  carouselListBox.Items.Add(new BitmapImage(Extensions.GetAbsoluteUri("Resources/covers/cover" + i + ".jpg")));
              }
