Moving Content Along an Elliptical Path

Follow these steps to move content along an Elliptical path:

From the Visual Studio File menu select New and choose Project.
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.
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
Right-click on the yourprojectname.Web project and select Add | Folder from the list. Name the folder Resources.
Right-click on the Resources folder and select Add | Folder from the list. Name the new sub-folder covers.
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.

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:

<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">

<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">

In the XAML view add a <Resources> tag just under the <UserControl> or <Window> tag and above the <Grid> tag with the following markup:
```
<Window.Resources>
</Window.Resources>
```
```
<UserControl.Resources>   
</UserControl.Resources>
```
You will add templates within this tag.

Add an ItemsPanelTemplate within the Resources tag to define the C1CarouselPanel:

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

Insert a <DataTemplate> to define the image source:

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

Add the following <Style> under the <DataTemplate> to set the PathGeometry property for the C1CarouselPanel control:

<Style x:Key="circlePanelStyle" TargetType="ListBox">
<Setter Property="c1:C1CarouselPanel.PathGeometry" Value="F1 M 466.829,27.2642C 635.339,35.6577 762.667,98.3819 762.667,173C 762.667,254.002 613.428,319.667 429.333,319.667C 245.238,319.667 96,254.002 96,173C 96,98.0584 224.402,35.1712 393.751,27.1714"/>
<Setter Property="c1:C1CarouselPanel.HorizontalPathAlignment" Value="Left"/>
<Setter Property="c1:C1CarouselPanel.VerticalPathAlignment" Value="Top"/>
<Setter Property="c1:C1CarouselPanel.PerspectiveAngle" Value="55"/>
<Setter Property="c1:C1CarouselPanel.PerspectiveFactor" Value="0.4"/>
</Style>

Add the following ListBox control within the <Grid>:

<ListBox Background="Transparent" Name="carouselListBox" Grid.Row="1"
ItemsPanel="{StaticResource carouselPanelTemplate}"
ItemTemplate="{StaticResource carouselItemTemplate}"
Style="{StaticResource circlePanelStyle}"/>

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

Add the following namespaces to the top of the page:

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;

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;

Insert the following method directly below the InitializeComponent() method:
```
InitData()
```
```
InitData();
```

Call the following method to populate the C1CarouselPanel with data:

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

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

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