The DropDownButton and SplitButton exhibit the following accessibility issues:

  • The screen reader cannot read the items in the DropDownButton and SplitButton popup.
  • When the DropDownButton is opened with Enter, the user cannot navigate the dropdown items with the arrow keys (tested in NVDA).

When SchedulerGroupOrientation is set to vertical, increasing the height of the `SchedulerResourceGroupHeader` breaks the rendering of the Scheduler cells, which causes misalignment of the appointments. In my scenario, I want to have a Button and an Icon in the group header cell.

Error: System.InvalidOperationException: Object of type 'Telerik.Blazor.Components.TelerikFilter' does not have a property matching the name 'ValueChanged'.

also in demo:

https://www.telerik.com/blazor-ui/documentation/components/filter/integration

<TelerikFilter @bind-Value="@AdvancedFilterValue">
	<FilterFields>
		@foreach (var it in GridDef.ColStore.Where(x => x.Verejny == true))

This issue is for all date inputs when having a higher latency (physical distance between the server and the end-user) the value of the date inputs is not correct. Additionally, When typing the year in the input field, the text overflows instead of staying within the 4-digit space. For reference, check the attached screenshot.

I am using ComboBox and I want to be able to filter by two model properties. To achieve this I have implemented custom filtering through the OnRead event. Additionally, I am ordering the data to first match the results from the one property, which also is used for the TextField, and after that to match the results from the other property. However, when the results are only from the match of the second property, there is no focus.

Here is a REPL example https://blazorrepl.telerik.com/wyaMQhEN108axXJ036 

Steps to reproduce the issue:

Type "a": "Value test - ano" has the focus (the first option in the list)

Type "an": "Value test - ano" receives the focus (the first option in the list)

Type "ano": "Value test - ano" receives the focus (the first option in the list)

Type "anot": no item has focus despite the results being only "Another Value - val"

I have been having issues adding the month view to a Telerik Blazor scheduler component, when there is grouping. It gives a null reference error any time I try to switch to the month view. I also tried it using the available demo for grouping in Telerik REPL, the only difference I found between my code and the demo was that I had used the ItemsPerSlot parameter.  I added this to the demo, and was able to reproduce the error I was seeing, and I have attached the console output from the REPL demo. I believe there is either a bug with the ItemsPerSlot being used in conjunction with grouping on a scheduler component, or some instruction missing from how to set it up properly to prevent this null reference issue. 

Changed code:

<SchedulerMonthView ItemsPerSlot="5"></SchedulerMonthView>

Demo used:

I have a cascading DropDownList scenario with virtual scrolling. When the first DropDownList changes value, the second one should reset its scrollbar to the top, because it now contains new data. This doesn't happen.

Here is a REPL test page.

ADMIN EDIT

As a workaround for the time being, you may track when the value is changed in the parent DropDownList to dispose and re-initialize the child DropDownList.

Here is an example: https://blazorrepl.telerik.com/mdafHabk585ZtzyV54.
