Glass mapper does not load item childeren

Question

We are facing issue in Glass mapper 4.0 where it does not load item children.

Here is our controller class , It is inheriting from GlassController:

public class CarouselController : GlassController
{
    public ActionResult GetCarousel()
    {
        Model = this.GetDataSourceItem<CarouselViewModel>();
        return View(Model);
    }
}

And here is our View Model:

public class CarouselViewModel:Carousel_Folder
{      
    [SitecoreChildren]
    public virtual IEnumerable<Carousel> Carousels { get; set; }
}

we get only the parent node information not the childeren (carousels) in the result

Here is the result we get:

[Result Image][1]

Also, following classes were generated with TDS:

[SitecoreType(TemplateId = ICarousel_FolderConstants.TemplateIdString )] //, Cachable = true
public partial interface ICarousel_Folder : IGlassBase
{}

Carousel template is inheriting from two templates content base and image base.

Are you sure the results are empty? Did you try to expand the results view? — Gatogordo, Jul 04 '16 at 14:54
Do you understand the difference between IEnumerable<> and List<>? — Mark Cassidy, Jul 06 '16 at 10:04

It seems that Carousels property is not par of the Carousel_Folder template, that's why your Interface/Class doesn't have something like:

[SitecoreType(TemplateId=ICarousel_FolderConstants.TemplateIdString)]
public partial class Carousel_Folder  : GlassBase, ICarousel_Folder 
{
    [SitecoreField(ICarouselConstants.CarouselsFieldName)]
    public virtual IEnumerable<Carousel> Carousels {get; set;}
}

In this case you will need to get the Parent item and get the children manually, i.e.:

var children = parentItem.Children.Select(x => x.GlassCast<Carousel>())

The `CarouselViewModel` inherits from `Carousel_Folder` and extends it with the `[SitecoreChildren]` definition so the model is correct for getting children of the item. The code you added is not needed (or what I would recommended) : http://www.glass.lu/Blog/GettingChildItems — jammykam, Jul 04 '16 at 21:38

I had this issue before, for me i added [SitecoreChildren(IsLazy = false)] to my model and it works fine, in your case it should be like this :

public class CarouselViewModel:Carousel_Folder
{

    [SitecoreChildren(IsLazy = false)]
    public virtual IEnumerable<Carousel> Carousels { get; set; }     

}

I have a query, I just google this "IsLazy" and came to know that by default it's value is false. So, why do we need to write it here explicitly? It will be great, if you can help me to understand this. – Ritu Suman Jul 05 '16 at 04:22
