Hi
I'm using lastest version
demo: https://dojo.telerik.com/eZOPEVeL
In offical demo i found a problem, i don't know that is a issue or any thing.
When i use DropDownList Virtualization, i filter "LILA-Supermercado" then selected a value 10780, then fire change event (that true)
Then, I open and close dropdownlist, does not choose any thing, just open and close, dropdownlist fire change event again (that not true)
this happen with any value which not loading before scroll.
some one help me
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
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.

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:

// $scope.data=0;
$scope.productsDataSource = new kendo.data.DataSource({

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

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
- Manually select a value for category (like Category 4); a console item should be written for user change
- Click the "change doc to empty" button which clears the category
- 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
