You prob. already know this, but in Chrome attribute autocomplete should be "disabled" instead of "off" for e.g. combobox - then we don't get the auto fill.

Even thought it has no id nor name - I think it looks at the lavbel - in my case its "Name" and the combobox get a big Chrome auto fill from the address book. Setting it from "off" to "disabled" will disable both auto complete AND auto fill.

The same goes for the AJAX Combobox - will you notify that team too? Current hotfix for that is `$(".rcbInput").attr("autocomplete", "disabled");`

A combobox that uses a grouped datasource does not adhere to WCAG 1.3.1. When a user navigates the options in the combobox popup, the group relationship is established for sighted users but the group is not announced to disabled users.

Currently, the "suggest" option of the ComboBox is designed to work only in a combination with 'filter:"startswith"'. If you open this Dojo and enter "T' in the ComboBox, then focus the ComboBox out then the "Two" ComboBox item will be selected.

If in the above demo, we change the filter configuration to "contains", when we enter "T" and focus the ComboBox out, the behavior will be the same, and "Two" will be selected. If we instead of "T" enter "w" and focus the ComboBox out then "two" won't be selected. To make the "Two" item selected, with "filter:'contains'" configuration, we can use the below workaround.

No matter the below workaround, it will be very useful if the below logic or similar one can be built-in in the ComboBox component.

<input id="combobox" />
var fruit = [
    {code: 1, name: "One" },
    {code: 2, name: "Two"},
    {code: 3, name: "Three"}

var ds = new kendo.data.DataSource({
data: fruit

  dataTextField: "name",
  dataValueField: "code",
   suggest: true,
   filter: "contains",
  dataSource: ds,
  change: function(e) {
    var comboBox = $("#combobox").data("kendoComboBox");
    var dataItem = comboBox.dataItem();
    if (dataItem === undefined) {
//special code for mobile browsers to auto select the first entry
if (comboBox.text() != "") {
ds.filter({ field: "name", operator:"contains", value: comboBox.text() });
if (ds.view().length > 0) {
comboBox.select(function(dataItem) {
return dataItem.name === ds.view()[0].name;
<input id="fred">

we found a hard to reproduce bug in the combobox control. It appears infrequently while typing in the combobox input, if the combobox has grouping and the fixed header enabled. It does not seem to have functional implications to the control but it produces a javascript error.


_firstVisibleItem: function () {
    for (var t = this.element[0], n = this.content[0], i = n.scrollTop, r = e(t.children[0]).height(), o = Math.floor(i / r) || 0, a = t.children[o] || t.lastChild, s = a.offsetTop < i; a; ) if (s) {
      if (a.offsetTop + r > i || !a.nextSibling) break;
      a = a.nextSibling
    } else {
      if (a.offsetTop <= i || !a.previousSibling) break;
      a = a.previousSibling
    return this._view[e(a).data('offset-index')]

It seems to be a timing problem where the list is already loading again while the scroll from the item selection is not finished.

Bug report
When submitting a selection in the ComboBox via Enter keypress an incorrect item is selected.

Reproduction of the problem
Run this dojo
Enter 199 in the input field and:
Click outside of the input field - text() returns 199, value() returns 199
Hit Tab key - text() returns 199, value() returns 199
Hit Enter key - text() returns 4, value() returns 199
With Kendo UI versions after 2018.2.516 pressing the Tab key outputs the same result as pressing the Enter key.

Current behavior
An incorrect item from dataSource is being selected on Enter keypress.

Expected/desired behavior
Selection modes should return same item.

Kendo UI version: 2018.2.516
Browser: [all]

As per https://docs.telerik.com/kendo-ui/api/javascript/ui/combobox/events/select I am expecting that select does not fire when the user enters text but does not select an item from the list. This is consistent with your other widgets like AutoComplete.


However as seen in this dojo https://dojo.telerik.com/ESOJibEB select triggers whenever I enter text and click off the box instead of only when I click an item in the combobox.


How to reproduce:

  • Open above Dojo
  • Click in the combobox and type some text.
  • Do not click on an item in the list and instead just click anywhere else on the page.
  • Check console and you will see select has been printed.


If you need any other help, let me know.


Kind Regards,



PS Im forced to select a browser but this is the same across both chrome and firefox.
