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 .
I have upgraded a huge project we have, from Kendo UI 2017 to the latest version.
I managed to fix all the incompatibility issues that I had with the latest version and now it's ready to go live.
In the final regression tests our customer found a bug and now we are stack and cannot deploy the project.
Here is the problem:
In the DropdownList, if you type something and then press the clear button, the change event is firing two times. One with the value that you typed before and then one again with an empty value (the right one). The biggest problem is that there is no way to determine that the first event is coming from the clear button and not from the user, so I cannot find any workaround this.
I searched and I found that this started after this change.
You can check this dojo for a reproduction of the problem.
Type "it" in the dropdownlist,
Wait for the items to popup
Don't select any item but press the clear button of the dropdownlist
You can see the attached image the wrong events.
If you select a version after 2019 R3, the change event is firing twice. If you select an older version the change event is not firing at all.
I can understand a change event with an empty value and I don't have any problem with that, but the first event is totally wrong.
Is there any quick solution to this so we can catch the deadline and deploy the new version of our project?
Thank you for your time,
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.
It will be very nice if the AutoComplete, DropDownList, ComboBox, and MultiSelect components have the floating label functionality like the TextBox widget
The model has the extra spaces trimmed and there is a single space between the words:
<pre class="ng-binding">Magazzini Alimentari Riuniti</pre>
In the DropDownList the value properly contains 2 spaces between the words.
In the data the selected item has 2 spaces between the words: Magazzini Alimentari Riuniti
The model value should be identical to the data and the extra spaces should not be trimmed.
In DropDownList when virtualization is enabled and the value of the widget is set through the value method, the cascade event is fired twice.
The cascade event will be triggered twice.
The cascade event should be triggered only once.
When there is no filter enabled in the DropDownList it is possible to select an item just by typing, without opening the DropDownList popup.
It would be useful if such an option is available when the filter of the widget is configured.
When filtering the DropDownList data when a limited amount of items remain the popup container is displayed above the DropDown element when sufficient space is available below the element
The popup container with the list of items should be displayed below the DropDown element when sufficient space is available below the element
The change event is being triggered when having an initially selected item in the DropDownList and then open the DropDownList and click on the default selected item. This bug is represented only in MVVM.
The change event of a DropDownList with initial data selected is being triggered when clicking on the already selected value.
Selecting the already selected item of a DropDownList shouldn't trigger its change event because there is no actual change in the component's value. Please check this Dojo for the expected behavior.
In the DropDownList and ComboBox, virtualization only works when the popup is open. In both widgets, item navigation is functional by pressing down to select the next item in the list without opening the popup. However, when the end of the first page of results is reached, the selection goes back to the top of the first page of results instead of loading the second page via virtualization. This misleads the user in that it only presents a portion of the options available. This is also an issue for disabled users and accessibility.
In both examples, holding down without opening the popup will never load more results.
We have had this issue in the past but it is a bigger issue now that we are focusing more on accessibility since users rely more heavily on keyboard navigation.
the multiselect control should have the possibility to define elements as not editable (readonly) so that those elements can not be removed while other elements can be removed or new elements can be added.
When the user enters a filter, the list is filtered. But if the user deletes the filter by clicking on the X in the filter box, the list remains filtered. It does not revert to the full, unfiltered list. To get back to the full list, the user must delete the filter by backspacing or pressing the delete key on the keyboard. This behavior is confusing some users, who have used the mouse to delete the filter in IE11. There's no longer a filter string there, but the list is still filtered. Can the dropdownlist listen for the click that clears the filter string from the textbox?
Populate selected items when using browser back buttons for both Html and MVC Wrapper versions
I'd like to be able to style the matching text from autocomplete, so I'd like the option for kendo to perhaps wrap the text in a span or something I can get a handle on... So if I typed "Back" it'll give me results like this <li><span class='t-match'>Back</span> to the future</li>
On MultiSelect have an option when they type in a complete name and then blur out to save that name. It works if they hit enter or tab. But if they don't (like if they immediately press the Submit button), then it looks it took their entry but it really did not.
Create the ability to customize tag templates on the combobox and autocomplete widgets just like the tag template functionality on the multiselect widget
Make up/down arrow keydown events fire a DropDownList change event when in the expanded state. When a user clicks on the DropDownList, the list gets expanded. There is no change event fired for up/down arrow keydown events. I currently have to intercept the up/down keydown events manually. Having up/down arrow keydown events fire a change event would make the widget more intuitive and helpful for user interactions.
Best practice dictates that dropdowns open on mousedown, such that that user can press, move to the desired item, and release all in one movement. You'll of course find this behaviour across many apps and OS's, including MS Office, Windows and OSX. Sadly, Kendo UI dropdowns open on mouseup/click, rather than mousedown, which means the user has to do two clicks to get to what they want. For heavy-usage applications, this is a big pain for users, and definitely affects usability.
