Need to add configuration to display value which is combination of two or more properties or fields in dataSource. Just like valueTemplate in dropdownlist list but without html tags, like

$('#comboboxinput').kendoComboBox({
    dataSource:[{Name:"English (US)", Value:"en-US"}, {{Name:" Japanese (Japan)", Value:"ja-JP"}}],
    template:"<div>#=data.Name+' - '+data.Value#</div>"
    complexValueFormat:"data.Name+' - '+data.Value"
})

I was working on a project where I was asked to display large number of items on dropdown list so i was using template and valueTemplate confugurations, since the items was too large to scroll we decided to use combobox but the problem is unable to display complex values after selecting an item. Currently I'm looping through all items and adding a property DisplayName to each item before setting dataSource. This feature will be very useful and replace dropdownlist if dataSource is too large and complex value is to be displayed.

I would love to see the ability to disable/enable items in the DropDownList dynamically at run time.  We have complex validation rules in our UI that need to prevent the user from using certain items if other options are selected.  

The big problem is the DropDownList doesn't let me enable/disable items or add/remove them. 

This means instead of having a few change events wired up to enable/disable items, I need to do it in complex validation rules.

I think the ability to disable/enable items would be a valuable feature to the kendo framework.

Regards,

Scott

The combobox currently doesn't react on the disabled-attribute for options. It should be possible to make single options visible but not selectable with this attribute as in original html-select:

I found no way to do this yet.

Currently to close the colorPicker manually, we have to do ".kendoColorPicker('close')", however the rest of the dropdowns/combos uses ".kendoPopup('close')".

It will be great to support it as well with colorPickers to allow closing of all popup elements on scroll with a uniform solution

Currently the data-* attributes on the <option> tags are removed by the kendoDropDownList widget.
Please pass them through so they can be used.

After searching the kendo.all.js I found that there is currently no way the custom data-* can be added into the generated html code.

I'm using MVVM for a rather large SPA. Some parts of the SPA is generated on the server (webservice) which is just a partial html. Which looks like (simplest one):
<select data-role="dropdownlist" name="ProductTypeID" class="k-textbox">
	<option value="9" data-cond="DependsValue(ProductTypeCategoryID,1)">Compliments cards</option>
	<option value="1" data-cond="DependsValue(ProductTypeCategoryID,1)">Flyers</option>
	<option value="3" data-cond="DependsValue(ProductTypeCategoryID,3)">Brochures</option>
	<option value="25" data-cond="DependsValue(ProductTypeCategoryID,6)">Roll-up banners</option>
</select>

In this case the data-cond is an attribute in which there is a (javascript) function that should be run to determine if this option is valid or not (it is made hidden if not).

I was trying to convert this into a datasource which can be bound to the dropdownlist, but this has several drawbacks. The most important are:

- There are almost 60 different of these kind of dropdowns that can be generated from the server; This means a lot of extra code and webservices.

- Calling the webservice for each of them is way to slow since each field changes conditional values of other fields, and so the server would be called way to often. But on the client side this runs way faster. Even in javascript.

- The data-* attributes should be supported accordingly the html5 standard to my humble opinion :)

I found two questions regarding this, but both where unanswered.

I add them here for you comfort :)

The problem with relying on maxlength that is built into HTML elements is that they do not work in instances where you are rendering multiple inputs as with the kendo-combo-box. If I set the max length, it sets the max length of the select, which is does nothing. It needs to transfer that maxlength to the input text which is rendered along with the select.

Yes, there are workarounds, but when you are using the controls in an angular mvvm environment where you write little to no jquery, the simplest fix should be to have the control code render the input fully given the information provided.

TLDR:
If given <select kendo-combo-box maxlength="3"
please generate <input class="k-input" type="text" maxlength="3"

I'd like to add separators between groups of items in a select / kendoDropDownList. Also known as a horizontal line or delimiter.
The same question was asked here by someone else: http://www.telerik.com/forums/separator-in-dropdownlist
The answer was that this is not supported.

Add support for autoScroll to DropDownList options, such that the list scrolls when the mouse pointer reached the top of bottom of the container. Currently, autoScroll: true has no effect on that component. 

Mouse wheel scrolling of the options is not obvious to users, causing some to miss options that overflow the container.

Adjust KendoDropDownList so that when the mouse scroll wheel does reach the end of the list the focus does not jump out of the control and scroll the form.

It would allow selected items(Tags) to be displayed as well as add new ones or select ones from an autocomplete dropdown.

I have created a new Telerk UI for ASP.NET Core R2 2018 SP1 Project and added a DropDownList Component into page.
When I use "Items" to add items manually everything is OK. but when I try to use DataSource to add Items using an Action remotely a console error is happened as "Uncaught TypeError: Cannot read property 'slice' of undefined".
JSON items is received and nothing is shown because of that error.
Please HELP

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 .

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/dropdownlist/virtualization

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.

I'm using your demo to reproduce the issue.  

When the user enters a value into the categories and tabs, the focus is not placed in the products field, instead it goes to the View Order button.  This makes using the cascade "feature" very difficult for users.  The focus should go products so they can further refine the search.  And then finally to orders.  But each time they tab they have to move the cursor back to the next field.

Also, since the product and order fields are disabled it prevents user from entering data (even if they know the correct value).  Is there a way to leave the cascade functionality whilst leaving the "child" fields enabled?  We were using it in a Region, Country, City filter, but because of these issues we have had to remove the cascade.

Expected behavior would be to leave all the fields enabled, if the user selects a category, then the subsequent fields (products and orders would be filtered to the selection) so that when the user starts typing in those the parent filter is added to their filter.

Whilst we are discussing filters, why if the filter is narrowed to a single item is it not automatically selected?  Currently the user has to filter, then select the item and then tab.  We have had numerous "bug" reports raised because the user didn't select before tabbing even though the item is the only one in the drop-down and appears to be selected.

Similarly the Mutliselect filter allows typing values, and even when the user selects the value in the dropdown and is added to the selected list, the typed text remains, making the mutliselect field value invalid on submission. 

Repro:

Open page: CascadeComboBox
Move focus to Categories combo (i used my mouse)
Type 'p' which opens the combo and shows 3 items starting with p
Select 'Products' using the down arrow (field now displays Products)
Click Tab
Focus moved to View Order button and NOT Products field.
Using the mouse to select a value works fine, but our users don't want to have to use the mouse as this slows down data entry.

I am using a DropDownList with dynamic items that are grouped.

When opening the dropdown without items in the datasource the fixed group header is displayed empty.

When removing the last item from the datasource after the DropDown has already been opened, the first group header is still displayed when opening the dropdown.

I would expect the group header to never be displayed if there is no data.

See Dojo: https://dojo.telerik.com/EviPepIJ

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]
