Render ListBox from Code behind

ListBox can be rendered from the code behind by initializing the required properties in controller and passing those properties via ViewData or Model to the client side.

The following code illustrates the initialization of ListBox properties in the controller.

C#

//Namespace to get the JavaScript (Listbox) component properties
using Syncfusion.JavaScript.Models;

namespace MvcApplication.Controllers
{
    public class ListBoxController: Controller
    {

        public ActionResult ListBoxFeatures()
        {

             // initialize data
            List<Bikes> bike = new List<Bikes>();
            bike.Add(new Bikes { id = "bk1", text = "Aachen RTR" });
            bike.Add(new Bikes { id = "bk2", text = "CBR 150-R" });
            bike.Add(new Bikes { id = "bk3", text = "CBZ Xtreme" });
            bike.Add(new Bikes { id = "bk4", text = "Discover" });
            bike.Add(new Bikes { id = "bk5", text = "Dazzler" });
            bike.Add(new Bikes { id = "bk6", text = "Flame" });
            bike.Add(new Bikes { id = "bk7", text = "Faze" });
            bike.Add(new Bikes { id = "bk8", text = "FZ-S" });
            bike.Add(new Bikes { id = "bk9", text = "Pulsar" });
            bike.Add(new Bikes { id = "bk10", text = "Shine" });
            bike.Add(new Bikes { id = "bk11", text = "R15" });
            bike.Add(new Bikes { id = "bk12", text = "Unicorn" });

            //Initializing the Listbox model

            ListBoxProperties ListObj = new ListBoxProperties();

            //Initializing the datasource and other properties

            ListObj.DataSource = bike;
            ListObj.ListBoxFields.Text = "text";
            ListObj.ListBoxFields.Value = "id";
            ListObj.AllowMultiSelection = true;

            //Passing Listbox properties using the ViewData

            ViewData["ListModel"] = ListObj;
            return View();
        }
    }
}

Binding the ListBox properties passed via ViewData from the controller in the client side as below.

CSHTML

@{
    Html.EJ().ListBox("bikeList", (Syncfusion.JavaScript.Models. ListBoxProperties)ViewData["ListModel"]).Render();
}
