The documentation for the Kendo UI MultiSelect widget states that the user can highlight the next/previous item using RIGHT/LEFT when the selection popup is closed. This works as expected. However, if the user then presses TAB and moves the focus somewhere else, the item remains highlighted.

Since the highlight only indicates that certain actions can be executed on the item, it should be removed in such a case as the actions are no longer executable. This can easily be reproduced with the keyboard navigation sample:

• Select a few items
• press LEFT
• press TAB

Bug report

When the value of the widget is set in the dataBound event handler the filtering events is fired and e.filter is undefined

Reproduction of the problem

1. Open the Dojo
2. Open the browser console and type something in the MultiSelect to filter the data.

Current behavior

The filtering event is fired a second time and the second time the e.filter is undefined.

Expected/desired behavior

Double-checlk if the filtering event should be fired a second time.
The e.filter and e.sender.dataSource.filter().filters[0] should return the same value.

Hi,

since the update to R3 2019 we have a issue with the multiselect component.

Whenever I set it to readonly:

$("#multiselect").data("kendoMultiSelect").readonly(true)

It is not possible to make it writable again with

$("#multiselect").data("kendoMultiSelect").readonly(false)

It stays readonly. What can I do?

Bug report

The "aria-setsize" attribute is missing when initializing a MultiSelect with default selected values in AngularJS

Reproduction of the problem

1. Open this Dojo and run it
2. Right-click on one of the initially selected items in the MultiSelect.
3. The selected DOM element will be a "li" tag
4. Select a new item in the MultiSelect and watch how the definition of the "li" tag will change
5. When selecting a third element in the MultiSelect. All the three "li" tags will receive an aria-setsize="3" tag, which wasn't presented for the default selected values

Current behavior

When initializing a MultiSelect with default values, the aria-setsize attribute is missing for these values.

Expected/desired behavior

The default MultiSelect values should have an aria-setsize attribute added to their selected values

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Bug report

In MultiSelect when the value is set initially and the mapValueTo option is set to 'dataItem', if the user first open and close the popup, the last item can not be removed and an error 'c.select(...).done is not a function' is thrown.

Reproduction of the problem

1. Open the Dojo example. - https://dojo.telerik.com/@NeliKondova/UCesAQen
2. Open the popup and scroll to the "Hungry Owl All-Night Grocers" item
3. Close the popup
4. Try to remove the "Hungry Owl All-Night Grocers" from the input

As the Dojo above does not use a remote valueMapper below is a sample project where a remote valueMapper method is implemented
WebApplication3.zip

Current behavior

The last item can not be removed and an error 'c.select(...).done is not a function' is thrown in the browser`s console.
The other items except the last one can be removed as expected. Also, all items can be removed initially in case the popup has not been opened and scrolled to the last item from the value.

Expected/desired behavior

It should be possible to remove all items displayed in the MultiSelect input, even in a scenario where the popup has been opened and closed.

The bug I was talking was when setting tagMode of kendoMultiSelect to single, clicking the clear button (x at right of textbox) doesn’t trigger “deselect” event. Not sure if it’s by design. They fixed a similar bug regarding “change” event - https://github.com/telerik/kendo-ui-core/issues/4649.

Repro snippet could be found at

https://dojo.telerik.com/AHAwETUx

• Open the MultiSelect and add some items
• Use backspace to remove items

Result: The items that were selected, then un-selected still show as selected in the list

This can be reproduced on the latest demo page. https://demos.telerik.com/kendo-ui/multiselect/index
