DataSource with Collection of Images

SfCarousel items can be populated with a collection of business objects. For example, a user may wants to create a SfCarousel control which will display a list of images.

  • c#
    • NSMutableArray<SfCarouselItem> carouselItemCollection = new NSMutableArray<SfCarouselItem> ();
for(int i=1;i<18;i++)
{
	SfCarouselItem item = new SfCarouselItem();
	item.ImageName = "image"+i+".png";
	carouselItemCollection.Add(item);
}
carousel.DataSource = carouselItemCollection;

    DataSource with Collection of custom view

    SfCarousel items can be populated with a collection of business objects. It can be achieved by passing the custom view into View property in SfCarouselItem

  • c#
    • SfCarousel carousel = new SfCarousel();

NSMutableArray<SfCarouselItem> listOfArray = new NSMutableArray<SfCarouselItem>();

for (int i = 1; i < 4; i++)
{
	SfCarouselItem items = new SfCarouselItem();
	UIImageView uiImageView = new UIImageView();
	uiImageView.Frame = new CGRect(0, 0, carousel.ItemWidth, carousel.ItemHeight);
	uiImageView.Image = new UIImage("Images/image"+i.ToString()+".png");
	items.View = uiImageView;
	listOfArray.Add(items);

}

carousel.DataSource = listOfArray;

View.AddSubview(carousel);

    It gets or sets the Selected Item index value of SfCarousel control to bring the particular item to center of the screen.

    NOTE

    The SelectedIndex property will be 0 by default.

    carousel.SelectedIndex = 2;
