If you expand a tree node with 1000 items in it, and that tree has an ng-template the performance is very poor. It takes 7 seconds on my machine, see here https://www.telerik.com/forums/slow-treeview-with-large-datasets

Please add virtualisation to the TreeView so that not so many DOM elements (and therefore ng-templates) need to be created.

Currently, the arrow keys can be used for navigating through the ComboBox items and making a selection.

However, since the group headers cannot be selected with the arrow keys (unlike the list items), the user cannot reach the first group header when going back up with the arrow keys in cases when the headers are not sticky: 

It would be great if the first group header can be scrolled into view when navigating back up with the arrow keys.

Please provide a template for customizing the value appearance of the DropDownList control types in the toolbar of the Editor, similar to the one available for the default DropDownList component:

• https://www.telerik.com/kendo-angular-ui/components/dropdowns/dropdownlist/templates/#toc-value-template 

At present, the only approach that can be used for configuring a value template is by implementing a custom DropDownList tool in the toolbar of the Editor:

• https://www.telerik.com/kendo-angular-ui/components/toolbar/custom-control-types/ 

Add functionality to the Java Spring Boot sample application to support server-side data operations, such as sorting, filtering, and pagination. Currently, the demo uses the process method to do the operations on the client.

It would be nice to have access to a valueChange event in the autocomplete similar to the other dropdowns. This way when binding against arrays of complex objects, we could receive the whole object selected instead of the single value property out of it.

In the Kendo ComboBox, the selection part is not working with shadow dom.

1. Reproduction:

Please look at the below links,

With ShadowDOM:

https://stackblitz.com/edit/angular-evkasb?file=app%2Fapp.component.ts

Without ShadowDOM:

An example is provided in the below link under 'ENABLING SUGGESTION' section

https://www.telerik.com/kendo-angular-ui/components/dropdowns/combobox/suggestions/

Expected Result:

When user type 'C', the first word starts with C in the list 'Croatia' is suggested and 'roatia' is selected. But as soon as I type 'y' next to 'c', the combo box is suggesting 'Cyprus' and 'prus' should be selected

Actual Result:

As soon as I type the first word starts with C in the list is 'Croatia' is populated in the Combobox and 'roatia' is NOT selected. So the user cannot type ‘y’ in this case. But the user wants to select ‘CYPRUS’ but 'Croatia' is filled as the input and Cyprus is not suggested.

I have attached the video for the difference between with/without shadow dom.

Also, If you need any additional information, I have created a support ticket:

Hello,

we have the need, to implement custom timeline views for the scheduler which shows a month and quarter timeline view.

This is currently not possible because the TimelineViewModule is not exporting the TimelineMultiDayViewComponent.

We request, to add this component to the exports and provide an updated dev version of the scheduler published to npm so that we can continue soon.

Thank you!

Best regards

Julian Hochstetter

Currently, when a MultiViewCalendar is rendered in the DateRange via kendoDateRangePopupTemplate, the adaptive mode of the DateRange does not reflect the templates defined for the MultiViewCalendar:

• https://stackblitz.com/edit/angular-v9fvvpzg

It would be great if the adaptive rendering of the DateRange could be enhanced to support the MultiViewCalendar templates. 

This will enhance the PDFViewer usability as the Toolbar provides many built-in features like responsiveness, tool customizations, etc., which will add extra value to the component.

The component is already used internally in the Editor and Spreadsheet.

The Scheduler Agenda view is cut when opened on a mobile device. The scheduler cannot be scrolled horizontally.

Please refer to the attached image.

Provide a way to be able to see all events in Agenda view on small resolutions.

Allow defining buttons in ButtonGroup component using NgTemplateOutlet:

  <kendo-buttongroup>
    <ng-container *ngTemplateOutlet="buttonsList"></ng-container>
  </kendo-buttongroup>

  <ng-template #buttonsList>
    <button kendoButton size="small">Button 1</button>
    <button kendoButton size="small">Button 2</button>
    <button kendoButton size="small">Button 3</button>
  </ng-template>

So far, the ButtonGroup doesn't appear when using this markup.

Currently, the ComboBox only supports "starts with" suggestions. When users type to input, only items that begin with the entered text are matched and focused.

Workaround overriding the default behavior:

Reorder tabs with drag and drop like so: http://demos.telerik.com/kendo-ui/sortable/integration-tabstrip

Any plans on creating a Distinct Filter for the grid? 

One like Wijmo has?  https://ibb.co/fo7gwQ

Allow user to filter like excel and your Keno UI for jquery. Where user can filter record by applying checkbox check and search.

Provide the ability to customize the cells' content of the Spreadsheet. SImilar to the custom cell editors of the Kendo jQuery Spreadsheet:
