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:

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
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
Reproduction of the problem
- Run this dojo
- Enter "123" - the popup container with the list of items is displayed below the DropDown element
- Enter "1234" - the popup container with the list of items is displayed above the DropDown element when sufficient space is available below the element
- Enter "12345" - the NoDataTemplate is displayed above the DropDown element when sufficient space is available below the element
Expected/desired behavior
The popup container with the list of items should be displayed below the DropDown element when sufficient space is available below the element

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.
Steps:
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,
John Dendrinos
Bug report
Even if no filtering is configured, when the delay option is different than 0 navigation between the items in the DropDownList does not work correctly.
Reproduction of the problem
- Open the Demo
- Focus/Open the DropDownList
- Click 's' - Small is selected
- Click 'l' - Large is selected
- Repeat multiple times
Current behavior
The correct item is not always selected. In the demo, no delay is configured, but the default value is 500. The delay is supposed to affect the DropDownList only when filtering is enabled.
Note: Currently, when the filter option is configured, changing selection without opening the DropDownList is not possible.
https://dojo.telerik.com/@iankodj/AhUgaXuf
Workaround
Set delay to 0 - Dojo
Expected/desired behavior
The selection of the items should be correctly changed when typing, even if a delay different than 0 is configured.
Also, it should be possible to change the selected item by typing in the keyboard even if the filter option is set and the DropDownList is closed.
Environment
- Kendo UI version: 2021.1.224

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
- On a Macbook Pro set the trackpad click to light
- Run this dojo
- 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
Environment
- Kendo UI version: 2021.1.330
- Browser: [all]
The dropDownList supports several keyboard shortcuts as documented in https://demos.telerik.com/kendo-ui/dropdownlist/keyboard-navigation. However, when e.g. a KeyDown event is triggered (and handled) by the widget, its propagation is not stopped. This behavior can be witnessed in this DOJO.
In our case, we e.g. use dropDownLists inside dialog windows that can be closed via ESC. When pressing ESC while a dropDownList is focused, this not only closes the dropDownList (as expected), but also closes the dialog.
The dropDownList should stop the propagation of events that it handled.
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.
Bug report
The change event is not fired when using the keyboard navigation in the DropDownList, if we first click in the filtering input.
Reproduction of the problem
- Open the Dojo - https://dojo.telerik.com/@NeliKondova/AnACEzIV
- Open the popup and use the up and down arrows to navigate between the items.
- Click in the filtering input.
- Press enter to select an item
Current behavior
Item is selected, but the 'change' event is not triggered. If we do not focus on the filtering input, the change event will be fired. It will be fired also if the mouse is used. - screencast
Expected/desired behavior
The change event should always be fired when the selection in the DropDownList is changed, even if the user clicks in the filtering input.
