You can customize the number of visible elements in the CarouselPanel by setting properties in either the <c1:C1CarouselPanel> tag in the ItemsPanelTemplate or in the <ItemsControl> tag.

To limit the number of visible elements in the CarouselPanel follow these steps:

1. From the Visual Studio File menu select New and choose Project.
2. In the New Project dialog box choose a language in the left-side menu, choose .NET Framework 4 in the Framework drop-down list, and enter a name for the project.
3. In the Solution Explorer, right-click the project name and choose Add Reference. In the Add Reference dialog box, locate and select the following assemblies and click OK to add references to your project:
   • Silverlight: C1.Silverlight.dll, C1.Silverlight.Carousel.dll
   • WPF: C1.WPF.dll, C1.WPF.Carousel       
4. Right-click on the yourprojectname .Web project and select Add | Folder from the list. Name the folder Resources.
5. Right-click on the Resources folder and select Add | Folder from the list. Name the new sub-folder covers.
6. Right-click on the covers folder and select Add |  Existing Item from the list.  For this Help, locate the covers that are included with the C1Carousel_Demo sample application.  Select all the files by pressing Shift and then clicking the first and last covers. Click Add to add the files to your folder.
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. Locate the <c1:C1CarouselPanel> tag and add the following XAML markup to limit the number of visible elements:

    PageSize="3"
    

    The total <c1:C1CarouselPanel> markup should resemble the following:

    XAML	Copy Code
    <c1:C1CarouselPanel Padding="0, 10, 50, 50" VerticalPathAlignment="Center" HorizontalItemAnchorOnPath="Center" VerticalItemAnchorOnPath="Center" PageSize="3"/>

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

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

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

    XAML

    Copy Code

    <Style x:Key="diagonalPanelStyle" TargetType="ListBox"> <Setter Property="c1:C1CarouselPanel.PathGeometry" Value="M 216, 60 L 600, 390"/> <Setter Property="c1:C1CarouselPanel.HorizontalPathAlignment" Value="Left"/> <Setter Property="c1:C1CarouselPanel.VerticalPathAlignment" Value="Top"/> <Setter Property="c1:C1CarouselPanel.PerspectiveAngle" Value="65"/> <Setter Property="c1:C1CarouselPanel.PerspectiveFactor" Value="0.12"/> </Style>

13. 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 diagonalPanelStyle}"/>

           

14. Right-click the MainPage.xaml page and select View Code from the list.
15. 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;

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

    Visual Basic	Copy Code
    InitData()

    C#	Copy Code
    InitData();

17. 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"))); }

18. Press F5 to run your application. The carousel should resemble the following image:
