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.

Environment

• Kendo UI version: 2023.1.117
• Browser: [Chrome]

Ticket ID : 1518454

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

When navigating between inputs and after using Shift+Tab for focusing on a previous input the DropdOwnList popup does not close on pressing 'Enter' key.

Reproduction of the problem

1. Open Dojo
2. Focus the text input
3. Press Tab to focus the DropDownList
4. Press shift-tab to focus the text input
5. Press again Tab to focus the DropDownList
6. Press Alt+down to expand the dropdown
7. Press the down arrow to select an option in the dropdown
8. Press Enter key

Current behavior

The popup does not close. If we directly focus the DropDownList and follow steps 6-8 the popup will close.

Expected/desired behavior

The DropDownList should close when pressing the 'Enter' key.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]

Bug report

When the width of the DropDownList is set using the list.width and the DropDownList gets open there is a slight delay of expanding the popup width.

Reproduction of the problem

1. Open the Dojo and open the DropDownList

Current behavior

There is a delay of expanding the popup width.

The issue is a regression starting with 2022 R1 SP1

####Workaround
$('.k-popup').width(600);
Dojo

Expected/desired behavior

There should be no delay when the width od the DropDownlist is set..

Environment

• Kendo UI version: 2022.2.802
• Browser: [all ]

Steps to reproduce:

1. Open the dojo using Google Chrome browser;

2. Open the first dropdown list;

3. Select any option from the list;

4. When the drop down closes, press Ctrl+V. The selected value changes for each time the keys combination is used.

 
Expected: CTRL+V combination does not trigger value selection.

It will be very nice if the AutoComplete, DropDownList, ComboBox, and MultiSelect components have the floating label functionality like the TextBox widget 

 

After updating the version of Kendo we are using to 2022.1.412 we noticed a weird behavior in the DropDownLists. Clicking the drop down arrow once opens the list, then clicking the arrow again closes and re-opens the list instead of just closing it. Note that this does not happen while clicking on any other part of the drop down to close it, selecting an item from the drop down, or clicking outside the drop down list. It only happens while clicking on the arrow button.

Behavior can be seen in the demos on these pages:

https://demos.telerik.com/kendo-ui/dropdownlist/template

https://demos.telerik.com/kendo-ui/dropdownlist/grouping

https://demos.telerik.com/kendo-ui/dropdownlist/cascadingdropdownlist

However the behavior does not appear on these pages:

https://demos.telerik.com/kendo-ui/dropdownlist/virtualization

https://demos.telerik.com/kendo-ui/dropdownlist/serverfiltering

 

Steps to Reproduce:

• Click the drop down arrow to open the drop down list
• Click on the arrow again and observe the list close and re-open (Note it sometimes doesn't happen right away but takes a few tries)

In our application, we have the requirement to display the DropDownList's filter textBox only if there are more than a specific number of items in the DropDownList. Therefore, we count the items everytime they change (i.e. an item is added/removed or perhaps all items are replaced) and then update the DropDownList's filter setting accordingly via setOptions().

Additionally, we use the dataBound() event for internal UI tweaks and therefore access the e.sender object.

This DOJO demonstrates that e.sender has a different structure before and after setOptions() is called. For instance, the list property does no longer exist. Check the console output, the event object is logged every time dataBound() is called.

Interestingly, this only happens when passing a complete (but updated) object to setOptions() and not when passing only a partial options object. Still, re-setting options to the same value as before should not interfere with any event args.

TL;DR: The DropDownList widget cannot be closed by clicking the arrow-icon.

The long story:

After the DropDownList has been opened once, it closes and reopens every time the user clicks the arrow-icon. Closing the DropDownList still works when clicking anywhere on the dropDown except the arrow-icon (or rather the button around it) or anywhere else but the dropDown. This DOJO demonstrates the problem. Animations have been disabled to allow easier reproduction (with animations on, the problem appears only occasionally, probably because of timing issues).

If you look closely, you will notice that the dropDown closes when the mouse button is pressed and reopens when the mouse button is released (this is when the click event is fired). Therefore, the problem can be (temporarily) mitigated by suppressing the mousedown event on the dropDown's wrapper element.

Describe the bug
While the loading icon is visible in the DropDownList when fetching data, the widget's height is changed.

To reproduce

1. Open this Dojo example - https://dojo.telerik.com/AFuQItIv/4
2. Select an item in the first DropDownList

You can compare the height of the two dropdownlists

Expected behavior
The height of the DropDownList shouldn't change when the loading icon is visible.

As my grid edit forms have expanded past the default popup, I have been using editable template. These are bound with MVVM and work well. But not all options work via MVVM like the cascade options below. I would like to use the cascade options in this scenario. It would be great to have all configuration options available via MVVM.

            <select id="ParentID" name="ParentID"
                    style="width: 100%"
                    data-role="dropdownlist"
                    data-text-field="Name"
                    data-value-field="ID"
                    data-cascade-from="ImprovementTargetID"
                    data-cascade-from-field="ImprovementTargetID"
                    data-cascade-from-parent-field="ID"
                    data-source="PEDropDownDataSource"
                    data-option-label="Pick PE..."
                    data-value-primitive="true"
                    data-bind="value:ParentID">
            </select>

Hello,

Drop down widget is defaulted to first option even though ng-model is undefined, in case where we bind same value to k-data-value-field and k-data-text-field.

Please have a look on the below sample code where you can find issue. My expectation is drop down should not default when model value is not assigned.

Hi Team,

I'd like to request the functionality to add a Clear Button  for the Kendo UI DropDownList similar to the ComboBox.  

Thank you!

Bug report

The height of the DropDownList popup is incorrect when using LESS themes.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/oMohisUF/2
2. Open the DropDownList

Current behavior

The popup height is incorrect.

Expected/desired behavior

The popup height should be big enough to fit the list.

Environment

• Kendo UI version: 2022.1.119
• Browser: [all]

Bug report

When filtering is performed in the parent widget and an item is selected, duplicate read request are sent to the remote end point for the child widget data.

Reproduction of the problem

1. Open the Dojo
2. In the parent DropDownList search "be" and select "Beverages"

Current behavior

Two requests are sent to the 'Products' DropDownList read end point.

Expected/desired behavior

There should be a single request for reading the widget`s data.

The issue is a regression since 2019 R3 SP1 (2019.3.1023)

Environment

• Kendo UI version: 2021.3.1109
• Browser: [all ]

The Kendo UI DropDownList allows the user to entera filter which is applied on the available items (documented here: https://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist/configuration/filter). As soon as a filter term entered by the user is applied to the dataSource, the selected item is no longer marked. Usually, the .k-state-selected CSS class is set on the corresponding DOM element.

This behavior can also be reproduced in the official Kendo UI Dojo about filtering: https://dojo.telerik.com/eVuSopuj

A kendoDropDownList places an arrow to the right of the <select/> element, indicating it's a dropdown (.k-i-arrow-s). It would be cool if kendoMultISelect did the same thing. 
Clicking the <select/> element or the arrow should also toggle the visibility on the list items.

See http://stackoverflow.com/questions/31825788/kendo-multiselect-to-have-arrow-icon-and-behavior-to-close-on-click .

https://dojo.telerik.com/iliKAqUr

1. select "Oranges" from the dropdown
2. press "Change value to 'Bananas'" button
3. press "Sort" button
4. select "Oranges" from the dropdown

Expected: should see two events for "Changed to Oranges" but only see one
Actual: status only shows one value change event from the first selection of "Oranges"

It seems this issue was introduced with the fix for https://github.com/telerik/kendo-ui-core/issues/4496

The introduction of _oldText in the _change method of kendo.list.js has introduced a flaw in the value change detection for DropDownList

The above dojo presents a way to short-circuit the issue since it is not easy to show the _oldText issue since the index check works as a fallback.

In Combox, DropDownList, Multiselect widgets, when grouping, the first item is incorrectly rendered (inconsistently with the others).

This can be observed as of today on:

1. https://demos.telerik.com/kendo-ui/combobox/grouping
2. https://demos.telerik.com/kendo-ui/dropdownlist/grouping
3. https://demos.telerik.com/kendo-ui/multiselect/grouping

Additionaly, when groupTemplate is defined, it's ignored for the first item: https://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist/configuration/grouptemplate

Bug report

When the DropDownList is used as an editor in the Gantt, sometimes the DropDownList popup closes on double-click. The issue is observed when the trackpad's click is set to light and a double-click is performed.

Reproduction of the problem

1. On a Macbook Pro set the trackpad click to light
2. Run this dojo
3. Double-click on an item in the title column

Current behavior

Sometimes the DropDownList opens and closes.
Screencast

Expected/desired behavior

DropDownList should remain open
