Do you have a planned date for Telerik UI for Blazor to fully support Visual Studio 2022 Professional?

Telerik UI for Blazor cannot be used with Visual Studio 2022 Professional in Debug mode and Hot Reload. There are couple issues, see below, that seems to be related, and that Telerik are not willing to fix. Those issues render Telerik UI for Blazor unusable when working with Visual Studio 2022 Professional with Hot Reload.

Predefined dialogs are not shown after hot reload updates are applied and Predefined dialogs throw when hot reload updates are applied

Hi !

I tried using the combobox but, since my datasource is too big and I need grouping, therefore virtualization is not possible, I need to do the filtering on the server side, using the OnRead method to fetch my data based on what the user has entered in the input field. The problem is that the client side filtering is always active and I can't reproduce the same type of filtering I do server side on the client side and I lose some results. I think it would be really nice if we could specify to not filter client side or something like that, to give us more control.

Thank you very much !

1. Can you please add the ability to choose a chevron instead of a caret to signify there are menu items under it?

2. Can you please add the ability to collapse/expand the menu and just show the icon when collapsed.

For inspiration - https://www.fluentui-blazor.net/NavMenuTree

Thank you.

When a TelerikComboBox is defined inside a window and the ContainmentSelector attribute is set for that window, the ComboBox exhibits erratic behavior: it sometimes fails to open, and selections from the dropdown may not register. Overall, the ComboBox does not function reliably in this configuration.

See attached video for current behavior.

If the ContainmentSelector attribute is removed, TelerikComboBox works as expected.

See attached example to reproduce the issue.

It would be beneficial to add an IsPrimary attribute to the TelerikButton, in order to allow to distuingish the primary buttons.

For example in DropDownList reflection is used for binding for TextField and ValueField.

As an additional option, I'd instead to be able to do DropDownList<FooBarModel>  and then FooBarModel implements a Telerik interface IDropDownListItem (for example but use your naming conventions)

I agree you shouldn't remove the option of using TextField / ValueField but I'd like to see it as an option.

Doing the same thing in something like DataGrid I agree would be a ton more work and we'd likely require using source generation.

It seems that Microsoft / the industry is consistently recommending to phase out the use of reflection and have invested a bunch in making source generation much less of a pain and developer friendly.

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

Where is the latest Telerik for Blazor Accessibility Conformance Report? The one on this page is over two years old: https://www.telerik.com/blazor-ui/documentation/accessibility/compliance#accessibility-conformance-report

Most organizations follow a 12-month cycle or update their ACR whenever there's a significant product version change, whichever comes first, to remain in good standing.

Please update the latest Telerik for Blazor Accessibility Conformance Report for the current version of Telerik for Blazor. We need these reports for the US States that use our software and Telerik for Blazor. Without current, valid VPATs, we will have to discontinue use of Telerik for Blazor.

DevExpress for Blazor has a current VPAT here for example (latest report Dec, 2025): https://www.devexpress.com/products/net/accessibility/ACR-DevExpress-Blazor-25.2.pdf

Hi, 

   I have a new laptop with a fresh install of visual studio and telerik etc etc.  When I went to get the ai coding assistants to work, nothing I did worked.  Spent hours trying to figure it out when Claude suggested I install NODE.  After I did that, and went the the telerik blazor extension to "Configure MCP server globally" the ai worked.

   First, have the configuration check to see if node is working and installed and give a warning if it is not, or let people know that it needs to be installed to make it work.  Secondly, add this to the documentation.  Such a pain in the ass when the documentation isn't complete.  The amount of time i spent on this is stupid compared to how simple the solution was.

Release 2026 Q2 (May)

I tried to use the TelerikDropDownTree component in my blazor application. When I activate the option ShowClearButton and click on the clear button, there is no update of the bound value or the ValueChanged event will be raised.

I can reproduce my issue with repl https://blazorrepl.telerik.com/wKOcviug54ZSE06146

Add the option to specify the initially selected tool within the Grid's GridToolBarSmartBoxTool. Currently, when the Search, Semantic Search, and the AI Assistant are enabled, the Search tool is selected by default.
