How can I populate this combobox with items from the controller onPage Load? The following is not working

<input id="CodeList" placeholder="Select" style="width: 100%;" />

<script>
    $(document).ready(function () {
        $("#CodeList").kendoComboBox({
            index: 0,
            dataTextField: "text",
            dataValueField: "value",
            filter: "contains",
            dataSource: {

                 transport: {

                        read: {

                            dataType: "json",

                            url: '@Url.Action("CompanyIDChanged", "Login")',

                         }

               }

            }
        });
    });
</script>

Controller:

Function LoanCodeCombo() As ActionResult
            Dim CodeList= New LoginModel With {.Items = {
                New SelectListItem() With {.Text = ""},
                New SelectListItem() With {.Text = "A"},
                New SelectListItem() With {.Text = "B"},
                New SelectListItem() With {.Text = "C"},
                New SelectListItem() With {.Text = "S"},
                New SelectListItem() With {.Text = "T"},
                New SelectListItem() With {.Text = "U"},
                New SelectListItem() With {.Text = "7"},
                New SelectListItem() With {.Text = "8"},
                New SelectListItem() With {.Text = "9"},
                New SelectListItem() With {.Text = "0"}
                }
            }
            Return Json(CodeList, JsonRequestBehavior.AllowGet)
        End Function

This my grid

Hello.

I have a Combobox widget that loads a ton of data using paging. Each element of the combobox has a DisplayName and an Id property.

The DisplayName propery is displayed on the input (UI) as an element is selected, the ID is the value that we use on our application's logic.

The problem starts when I select a value that it's not in the first page and the save the data. When we open the widget again, the ID value is displayed on the UI until I scroll to through the combobox elements and it loads the selected value.

I'm guessing that the id property it's being displayed there because it's the only property saved by us and the DisplayName is not loaded yet.

Is there any way to get the selected element using the saved Id ?

I have a kendoComboBox that I have configured with Server filtering. (autocomplete like functionality)

When a certain action occurs, I want to have the combobox select an item that I supply in code.  i.e. I want to set the text AND the selected value of the combobox, and then disable the combobox.

I know I can set the text with widget.text("something").  However, the value function also sets the text.  (widget.value("1111");)

So my next attempt was to set the datasource of the combobox to the object, and then call widget.select(0).

However, this doesn't seem to do anything.  (except disable the widget)  The dataSource is getting set, but underlying value and the text are not changing.  Also, the dropdown is empty. (if I don't disable it)   

dataTextField is set to "name", and dataValueField is set to "itemID".

Any help would be appreciated.  Thanks.

  I have a kendoComboBox, with an associated dataSource that has more items than the PageSize. This comboBox is bound to one my columns in the grid. When creating a new record, i can access the items for this comboBox, that are not in the first 'pageSize items', by using the comboBox's filter and suggestion features, so i start typing, and can access a previously unloaded item. My problem occurs after i have created a record, and selected an item in this comboBox, that was not loaded at first on the dataSource, that is, an item greater than the PageSize. When i open the popup, and try to edit such a record, the comboBox is unable to find the previously selected item and, only displays the item's value field, instead of it's text field. From what I understand, because the item is not loaded in the dataSource by default, since it is greater than the PageSize, the comboBox's dataSource is unable to find the dataItem an assign it to the comboBox. So, what i would like to know, is if there is a way to load items that are larger than the dataSource's pageSize, when editing a record that already has these items selected on their comboBoxes.

The default functionality of kendo jquery combobox is that whenever we search something and hit tab it selects the item and in the next tab hit, the focus goes to the next input . However I want to combine these two steps, so that only one tab hit should select and move the focus to the next element. (e.g in devexpress https://demos.devexpress.com/MVCxDataEditorsDemos/Editors/ComboBox  if you search in the combobox and press tab it selects the drop-down item and focuses on next input immediately). Is it possible to do in kendo combobox?
