Hello,

I tried with below code and also faced same issue in IE while its worked perfectly in FF.

public JsonResult GetCity(string Value)
       {
           int count = DateTime.Now.Second;
 
           List<SelectListItem> lst = new List<SelectListItem>();
 
           for (int i = 0; i < count; i++)
           {
               SelectListItem l1 = new SelectListItem();
               l1.Text = "Name" +i.ToString();
               l1.Value = i.ToString();
               lst.Add(l1);
           }
 
           return Json(lst, JsonRequestBehavior.AllowGet);
       }

<div id="example" class="k-content">
    Select a title from Netflix:
    <input id="titles" />
    <button id="a" onclick="Refreshddl();" />
</div>
<script type="text/javascript">
    $(document).ready(function () {
 
        var newdataSource = new kendo.data.DataSource({
            transport: {
                read: {
                    url: "Home/GetCity",
                    data: {
                        Value: "0"
                    }
                }
            }
        });
 
        var aa = $("#titles").kendoComboBox({
            index: 0,
            placeholder: "Select City",
            dataTextField: "Text",
            dataValueField: "Value",
            filter: "contains",
            dataSource: newdataSource
        });
 
    });
 
 
    function Refreshddl() {
 
        var newdataSource = new kendo.data.DataSource({
            transport: {
                read: {
                    url: "Home/GetCity",
                    data: {
                        Value: "0"
                    }
 
                }
            }
        });
 
        var ddl = $('#titles').data("kendoComboBox");
        ddl.setDataSource(newdataSource);
        ddl.refresh();
 
    }
     
 
</script>

Hello,

 
As it is stated in the docs, the refresh method of the widget does not reload the data of the DataSource. To reload the data use the read method of the dataSource.

All the best,

Hello Jayesh,

 
I prepared a simple test page in order to check the behavior of the ComboBox in FF and IE, but everything works as expected. Check this screencast for more information. Let me know if I am missing something.

Kind regards,
