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.

read was working, i stared to add new features to my existing project but noticed that read method not working, i call read method the  requestStart and requestEnd methods not triggered and also no network traffic exists when pressed F12, there is no failure alert

    console.log("reloadBrancheStore");
    brancheStore.options.transport.read.data.areaId = getAreaIdsForUrl();
    brancheStore.options.transport.read.data.cityIds = getCityIds();
    brancheStore.options.transport.read.data.companyIds = getCompanyIds();
    console.log("reloadBrancheStore before  read");
    brancheStore.read();
    console.log("reloadBrancheStore after read");

Hi,

Here you will find a small example where on a button click the dataSource read method is called and the returned data is loaded in a Grid.

I will appreciate any detail on how the behavior on your side can be replicated. Could you please try to prepare a Dojo example and send it back.

Regards,

Hello,

i agree with you.

Why my above code have different behavior for FF and IE?

Can you please check/explain this issue?

Thanks,

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.
