Render Rotator from Code behind

Rotator 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 Rotator properties in the controller.

C#

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

namespace MvcApplication.Controllers
{
    public class RotatorController: Controller
    {
        public ActionResult RotatorFeatures()
        {

             // initialize the data list

           List<LocalData> localValues = new List<LocalData>();

            localValues.Add(new LocalData { Text = "Beautiful Bird", Url = "../Images/rotator/bird.jpg" });

            localValues.Add(new LocalData { Text = "Colorful Night", Url = "../Images/rotator/night.jpg" });

            localValues.Add(new LocalData { Text = "Technology", Url = "../Images/rotator/tablet.jpg" });

            localValues.Add(new LocalData { Text = "Nature", Url = "../Images/rotator/nature.jpg" });

            localValues.Add(new LocalData { Text = "Snow Fall", Url = "../Images/rotator/snowfall.jpg" });

            localValues.Add(new LocalData { Text = "Credit Card", Url = "../Images/rotator/card.jpg" });

            localValues.Add(new LocalData { Text = "Amazing Sculptures", Url = "../Images/rotator/sculpture.jpg" });

            //Initializing the Rotator model

            RotatorProperties RotatorObj = new RotatorProperties();

            //Initializing the datasource and other properties

            RotatorObj.DataSource = localValues;
            RotatorObj.RotatorFields.Text = "Text";
            RotatorObj.RotatorFields.Url = "Url";
            RotatorObj.SlideWidth = "600px";
            RotatorObj.SlideHeight = "350px";
            RotatorObj.ShowPlayButton = true;

            //Passing Rotator properties using the ViewData

            ViewData["RotatorModel"] = RotatorObj;

            return View();
        }
    }
}

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

       Html.EJ().Rotator("sliderContent", (Syncfusion.JavaScript.Models.RotatorProperties)ViewData["RotatorModel"]).Render();
