    How can I get carousel on page?

    Using Umbraco And Getting Started
    Umbraco 8

    Hi all,

    I want to create a carousel, firstly I create a nested content then I added it on my homepage but when I called, it's not working. 

    @{
      string carouselId = "mainCarousel";
      IEnumerable<IPublishedContent> carousel = Model.Value<IEnumerable<IPublishedContent>>(carouselId); }

    I got error like this object reference not set to an instance of an object. I tried many things but I failed to reach on solve. Btw I'm using v8.1.12.

    Hi Caglar

    You have to use IPublishedElement instead of IPublishedContent like this:

    @{
      string carouselId = "mainCarousel";
      IEnumerable<IPublishedElement> carousel = Model.Value<IEnumerable<IPublishedElement>>(carouselId); }

    If you have single element nested content then like this:

    IPublishedElement carousel = Model.Value<IPublishedElement>("mainCarousel");

    All information needed for working with nested content you can find here - https://our.umbraco.com/documentation/getting-started/backoffice/property-editors/built-in-property-editors/Nested-Content/

    Thanks,

    Alex

    It doesn't work . I really don't know why I'm getting this error.

    My nested content;

    enter image description here

    Then I added this property on my home document type like as;

    enter image description here

    After, I filled with data in content menu and I clicked save&publish. After I called all this process on my partial view.

    I fixed this problem with this code;

    var page = Umbraco.Content(Guid.Parse("eea1803b-f093-42f6-8483-b27df3323c2d"));
var carousel = page.Value<IEnumerable<IPublishedElement>>("mainCarousel");
