In this step, you will add a C1CarouselExtender control to associate with the Panel to create the carousel.
<cc1:C1CarouselExtender ID="Panel1_C1CarouselExtender" runat="server" Display="1" TargetControlID="Panel1">
</cc1:C1CarouselExtender>
Now you can begin setting properties for the C1CarouselExtender to format the carousel.
