Zebble.Carousel

Carousel plugin allows the user to swipe from side to side to navigate through views, like a gallery slider.

Setup

• Available on NuGet: https://www.nuget.org/packages/Zebble.Carousel/
• Install in your platform client projects.
• Available for iOS, Android and UWP.

Api Usage

<Carousel Id="MyCarousel">
	<ImageView Path="..../Slide1.png" />
	<ImageView Path="..../Slide2.png" />
	<ImageView Path="..../Slide3.png" />
	...
</Carousel>

For adding a slide view in code behind to you Carousel use AddSlide(myView) method.

MyCarousel.AddSlide(new Canvas());

You can style the Carousel-Bullet and it's active state like this:

Carousel-Bullet{ 
	background-color:#eee;
	  &:active{ background-color:#333; 
	  } 
	}

Dynamic data source

In the above example, you can use a <z-foreach> loop to dynamically create slides from a data source. For instance, the following code will show a slide for each image file inside the MySlides folder in the application resources:

<Carousel Id="MyCarousel">
	<z-foreach var="file" in="@GetSlideFiles()">
	   <ImageView Path="@file" />
	</z-foreach>
    <AnyOtherView />
</Carousel>

Code behind:

IEnumerable<string> GetSlideFiles()
{
     return Device.IO.Directory("Images/MySlides").GetFiles().Select(x => x.FullName);
}

Methods

RecyclerCarousel

Normal carousel is very flexible. Each slide can be any view object. But it requires all slides to be pre-rendered, which is not efficient if you have many.

In cases where you have several views all with the same templates, it's much more efficient to use RecyclerCarousel which is much much faster.

<RecyclerCarousel z-of="Product, SlideTemplate" DataSource="@Products">
    <z-Component z-type="SlideTemplate" z-base="RecyclerCarouselSlide[Product]">
        <ImageView Path="@{Item, x=>x?.Thumbnail}" />
        <TextView  Text="@{Item, x=>x?.Name}"/>
    </z-Component>
</RecyclerCarousel>

In the above example, Products is an IEnumerable<Product> which is the data source from which to populate the slides. For example you may have 10 product instances in an array. The carousel will always render a maximum of 3 items. As you swipe through the slides, it will reuse the slide ui objects and just change their X position and also update the data source which is the Item property. Please note that Item is a Bindable<Product> which means you need to use the @{Item, x=>x.Something} syntax in your template.
