Accessing the Data Source of a Control

Question

I have a control property with a data source pointing to a folder with items with fields.

Is there a way to loop through the children of the item in the data source and display them on my view?

In my view I have:

@using Sitecore.Mvc.Presentation
@using Sitecore.Mvc
@model RenderingModel

In my controller I have:

public ActionResult Index()
{
    var renderingModel = new Sitecore.Mvc.Presentation.RenderingModel();
    var myTitle = renderingModel.PageItem.Fields["Title"].Value;
    var item = Sitecore.Mvc.Presentation.RenderingContext.Current.Rendering.Item;
    var itemPageContext = Sitecore.Mvc.Presentation.RenderingContext.Current.PageContext.Item;
    return View();
}

Answer 1

Controller:

public class RotatorController : SitecoreController 
{
  public ActionResult Index()
  {
    var dataSourceId = RenderingContext.CurrentOrNull.Rendering.DataSource;
    var dataSource = Sitecore.Context.Database.GetItem(dataSourceId);

    var viewModel = new RotatorViewModel
    {
      RotatorItems = dataSource.Children
    };
    return View(viewModel);
  }
}

View Model:

public class RotatorViewModel
{
  public IEnumerable<Item> RotatorItems { get; set; }
}

View:

@model RotatorViewModel 

<h1>This is a rotator!</h1>
@foreach (var item in Model.RotatorItems)
{
  <h2>@item.Fields["Title"]</h2>
}

Since you have @model RenderingModel, you could access the datasource item via Model.Rendering.Item. To loop over the child items of the datasource you would do something like this:

@foreach(Item child in Model.Rendering.Item.Children)
{
    <div>@child.Name</div>
}

Answer 3

Try this

Sitecore.Mvc.Presentation.RenderingContext.Current.Rendering.DataSource

You will get your datasource item (Home Page Rotator) ID.

Then you can obtain children and pass whole collection to the View via Model and display whatever you want.

Answer 4

I access a Data Source which is a folder of content items having a Name field and a Price field. In the View Rendering, my Data Source is set to /sitecore/content/Products which is the folder containing the projects. In my View Rendering cshtml file I have the following:

@using Sitecore.Data.Items
@using Sitecore.Mvc.Presentation

<table>
    @foreach (Item product in RenderingContext.Current.Rendering.Item.Children)
     {
        <tr><td>@product["Name"]</td><td>@product["Price"]</td></tr>
     }
</table>

This accesses the data source in a simpler way. This is with Sitecore 9.
