all items to be checked by default

[yeadam]

Hi

Is it possible for all items to be checked by default when the page loads?

Hi Yeadam, 

  

Thanks for contacting Syncfusion Spport. 

 

We have checked your reported query, and we can achieve your requirement by calling selectAll method with true, from created event handler. 

 

Index.cshtml 

<ejs-listbox id="listbox" dataSource="@ViewBag.data" created="created"> 

    <e-listbox-selectionsettings showCheckbox="true"></e-listbox-selectionsettings> 

</ejs-listbox> 

 

<script> 

    function created() { 

        var listBox = ej.base.getComponent(document.getElementById("listbox"), "listbox"); 

        listBox.selectAll(true); 

    } 

</script> 

 

HomeController.cs 

using Microsoft.AspNetCore.Mvc; 

namespace WebApplication1.Controllers 

{ 

    public class HomeController : Controller 

    { 

        public IActionResult Index() 

        { 

            ViewBag.data = new string[] { "BadmHennessey Venominton", "Bugatti 

              Chiron", "Bugatti Veyron Super Sport", "SSC Ultimate Aero", 

              "Koenigsegg CCR","McLaren F1", "Aston Martin One- 77", "Jaguar XJ220"  

            }; 

            return View(); 

        }   

    } 

}
