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.

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]

Hello Patrick,

Thank you for your feedback. I managed to reproduce the scenario in this Dojo example. The current behavior looks like a bug. Therefore I have converted this thread to a Bug report in our Feedback portal. I also provide you a link with the issue to our public GitHub repository where you can also find further information on the matter. Until the bug is fixed, I would recommend you not to use 0 as grouping criteria in you project.

I also updated your Telerik Points as a thank you for your feedback.

The "change" event on DropDownList is being triggered when the value change of the widget is via API and not triggered by user interaction.

Steps to reproduce:

https://dojo.telerik.com/oKeBEZUN

  1. Manually select a value for category (like Category 4); a console item should be written for user change
  2. Click the "change doc to empty" button which clears the category
  3. Click the "change doc to values" button which programmatically sets the category

Expected: a log item is NOT added because the change was programmatic and the log item is triggered on "change"
Actual: a log item is added even though the value change was programmatic

The change detection inside the select widget is faulty in that it seems to be effected by focus/blur state.

This issue was found after upgrading kendo UI.  I believe the issue was introduced in 2018.1.117

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. 

 

Code:

            k-data-value-field="'name'"
            k-data-source="productsDataSource"
            style="width: 100%"></input>


</div>
</div>

<script>
  angular.module("KendoDemos", [ "kendo.directives" ])
      .controller("MyCtrl", function($scope){
   // $scope.data=0;
    $scope.productsDataSource = new kendo.data.DataSource({
                        data: [{
            'name':'Active','id':0

          },{'name':'Cancel','id':1}]
                    }
                );





      });

When using AngularJS binding for dropdownlist options in the latest version of Kendo (2018.3.1017), the option labels are not dynamically bound to the scope/controller.  I changed one of the options to have the label {{::foo}} and set the field foo to "BAR" when initializing the scope.  When I run this code with the latest version, the literal text "{{::foo}}" is displayed for the first item of the drop down.  When I use an older version of Kendo (2018.2.516), the text "BAR" is displayed for that item.  This is a regression bug that is causing an error in our product.

Here is a testcase that illustrates the problem.  To toggle between the working and broken versions, change the CDN values.

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

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.

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.

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.

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"
1 2 3 4
