Currently, the Virtualized DropDownList does not handle the autoWidth property, as describe in the offical client-side API documentation.

It would be beneficial if there is a way to circumvent around this limitation.

Hi 

I'm using  lastest version 

demo: https://dojo.telerik.com/eZOPEVeL

In offical demo i found a problem, i don't know that is a issue or any thing.

When i use DropDownList Virtualization, i filter "LILA-Supermercado" then selected a value 10780, then fire change event (that true)

Then, I open and close dropdownlist, does not choose any thing, just open and close, dropdownlist fire change event again (that not true)

this happen with any value which not loading before scroll.

some one help me

Bug report

When remote data is loaded in the DropDownList and the loading icon appears while loading, the down arrow icon remains visible. Thus, both icons are overlapping.

Reproduction of the problem

1. Open the Dojo
   Note: if the data loads fast and the issue does not occur, open the browser developer tools in order to hit the debugger in the requestEnd event handler

Current behavior

Both - the loading indicator and the down arrow icon appear at the same time:

Expected/desired behavior

The down arrow icon should disappear while the loading indicator is displayed.

The issue is a regression starting with the 2023 R2 (2023.2.606) version

Environment

• Kendo UI version: 2023.3.1010
• Browser: [all]

The dropDownList supports several keyboard shortcuts as documented in https://demos.telerik.com/kendo-ui/dropdownlist/keyboard-navigation. However, when e.g. a KeyDown event is triggered (and handled) by the widget, its propagation is not stopped. This behavior can be witnessed in this DOJO.

In our case, we e.g. use dropDownLists inside dialog windows that can be closed via ESC. When pressing ESC while a dropDownList is focused, this not only closes the dropDownList (as expected), but also closes the dialog.

The dropDownList should stop the propagation of events that it handled.

Bug report

`DropDownListSelectEvent.dataItem` is undefined when using keyboard to select the optionLabel, but is defined when using the mouse

Reproduction of the problem

Steps

Dojo: https://dojo.telerik.com/IvEXOvUH

Make a selection (e.g. "Apples").
Select the optionLabel item.

Expected

The value of DropDownListSelectEvent.dataItem is the same whether the selection is made via keyboard or mouse (assumedly).
The value of DropDownListSelectEvent.dataItem is clearly specified in the API docs when selecting the optionLabel.

Actual
The value of DropDownListSelectEvent.dataItem is "Select an option…" when selecting with the mouse.
The value of DropDownListSelectEvent.dataItem is undefined when selecting with the keyboard.

Environment

Hi Team, 

I would like to request to add a class which associates with the Kendo DropDownList.  This way, the developer could use CSS instead of jQuery to change the style of the specific popup.  

Thank you!

Bug report

The value of a disabled DropDownList is not announced in the below screen reader -> browser combinations:

NVDA with Chrome
JAWS with Chrome

The value is correctly announced by NVDA in Firefox.

After testing the scenario with the ComboBox, the value was correctly announced in all screen reader -> browser combinations.

Reproduction of the problem

1. Open this Dojo example in Chrome with JAWS/NVDA - https://runner.telerik.io/fullscreen/ERAxiqIy/3
2. Click the Enable checkbox
3. Select a value from the DropDownList
4. Click the Enable checkbox again.
5. Focus the Checkbox and press the down arrow key.

Current behavior

The screen reader announces the disabled state of the DropDownList, but does not announce its value.

Note - the value of the regular select element below the DropDownList is announced.

Expected/desired behavior

The value of the disabled DropDownList should be announced in the above mentioned combinations.

Thank you for your kind reply.

I saw the link you sent me.(https://dojo.telerik.com/eHUBOtOW/2)

When a Korean keyword is searched, the cursor is pushed back.

It works fine in Chrome, but the same thing happens in IE.

Our company's system have to use IE.

Bug report

Current behavior

Item is selected, but the 'change' event is not triggered. If we do not focus on the filtering input, the change event will be fired. It will be fired also if the mouse is used. - screencast
