Can I create an empty DropDownList?

[Tomislav Tustonic]

Hello

Is it possible to have an empty DropDownList. When my datasource returns 0 items, I get an error:

Error: Unable to get property '0' of undefined or null reference

Thanks,

Tom

Hi Tomislav Tustonic, 

Thank you for contacting Syncfusion Support. 

We analyzed your query. As per your requirement, we set dataSource with  0 item. Please refer the code block below, 

[Controller] 

List<groups> group = new List<groups>(); 

         

        public ActionResult DropdownlistFeatures() 

        { 

           ViewBag.datasource = group; // 0 items send to the DropDownList 

            return View(); 

        } 

[View] 

@(Html.EJ().DropDownList("ddAssociationListAssociationGroupFilter").ShowCheckbox(true).EnableAnimation(true).Datasource((IEnumerable<groups>)ViewBag.datasource).DropDownListFields(f => f.Value("id").Text("Name"))) 

 

Please ensure this in your end. 

Please find the sample in the below location,
