Bug report

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.

Reproduction of the problem

1. Open this Dojo and run it. The three cascading DropDownLists will have default selected items
2. Click on the first DropDownList and select the already selected "Confections" option
3. The other two DropDownLists will be reset because of the change event thrown in the first DropDownList

Current behavior

The change event of a DropDownList with initial data selected is being triggered when clicking on the already selected value.

Expected/desired behavior

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.

Environment

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

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.

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

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.

to have Accent Folding support for kendo combo box. We are using generic html/Jquery to do this now. Is there a work around or and any suggestions.

Users wonder why the filter has not been removed from the dropdownlist when they use a browser's text INPUT[X] to delete the filter. The browser raises no event is raised when the X is clicked, and so the list does not revert to the unfiltered list. Users must hit the Delete keys on the keyboard. Although developers can use CSS to remove the browser's [X], it would be more convenient if kendo could do this by default for the dropdownlists's filter box, so that developers would not have to remember to add the CSS every time.

Hi Support Team,

Current, we are facing a problem when using "kendo ComboBox" and options in attachment. To reproduce this issue, you have to run sample(kendoui.web.2013.1.319.commercial\examples\web\combobox\index.html) from attachment on safari of iPad.
Step by step:
1. Click on arrow icon to expand items
2. Click on textbox
3. Type data to search items near the last item on textbox

Actual: ComboBox don't auto scroll to item of user typed.

If you're trying to create an accessible form, "the value of the for attribute must be the same as the value of the id attribute of the form control" [1]. Since the ComboBox widget generates a new element and hides the original select element, the for attribute no longer matches this new input element. I think it would be good if the ComboBox widget would somehow keep the for attribute of the associated label element in sync with the newly generated input element.

ComboBox and DropDown are different because the first allows you to enter values non in list, but if you are using Cascading ComboBox, entering a value non in list in the first choice, the second choice is disabled. I'like to have cascading for values in list with option for inserting values non in list.

Currently it is not possible to show the filter row until some data has been received and the dropdown is visible.

Please enhance/change the DropDownList widget so that it will be possible the enter a filter expression before any data is queried.

Not showing the selected items externally , only within the drop down.

Now autocomplete can not use to suggest email input, just like I input my name, the widget can show myname@xxx1.com, myname@xxx2.com, myname@xxx3.com like this, and the data will be only [{"email":"@xxx1.com"},{"email":"@xxx2.com"},{ "email":"@xxx3.com"}]

Currently when a combo box is used on an edit form, when the combo box first loads, the value property it is bound to (e.g. an int id) is displayed as the text until the databound event fires, and the text value associated with that value can be loaded.  It gives the combo boxes an unprofessional look, as they briefly display a number until they are done loading.  It also creates some other problems when you have a custom filter function, as described here:

I recognize that you would not want to change the default behavior since it would be a breaking change, but could you add a flag to toggle this behavior off.  You could add a property called "DefaultTextToValue" which is set to True by default, and if you set to false, the display would remain blank until the text value was set by the databound event.

Hi guys! I am glad to be back with another feature suggestions for future Kendo UI releases. I am currently working on a project for a client using Kendo UI Multiselect control. The client's pizza ordering system has an interesting feature for selecting double or single portion ingredients. Currently, I'm only able to display the selected items individually, so what it means is that in the selected items, you see 2 of those same items. Perhaps in the future release, can you have some sort of checking to see if there is double entries, and group those into something like "Cheese (x2)". Honestly, this will make Multiselect so much more cooler!! And when the user decides to click on the "X" beside the item with double items, it simply removes one of the selected items by removing the ",id", and then removes the (x2) text. And ofcourse, for better user experience, Kendo UI Multiselect should automatically calculate the number of a single id has been added everytime the user selects the same item.
