Hello everyone,

Here are the highlights of the new online resources we published this week from 13 Oct 2025 to 20 Oct 2025:

Article: https://www.telerik.com/blazor-ui/documentation/knowledge-base/grid-access-gridsearchbox-value
Summary: The article shows how to get the current search text from the Telerik UI for Blazor GridSearchBox so you can use it in custom logic. Capture it by binding GridSearchBox.Value or handling ValueChanged in the Grid toolbar; for OnRead/server binding, extract the quick-search term from GridReadEventArgs.Request.Filters (the OR composite filters produced by the search) or from the grid state via OnStateChanged.

Article: https://www.telerik.com/blazor-ui/documentation/knowledge-base/dockmanager-add-content-pane-footer
Summary: Add a sticky footer to a Telerik UI for Blazor DockManager ContentPane by wrapping the pane content in a full-height container and using CSS (flex column or grid) so the main area scrolls while the footer stays pinned to the bottom across docked, floating, and tabbed states. The article shows the pane content structure and required styles (height: 100%, overflow, borders) to place actions or status info in the footer without affecting the DockManager layout.

Article: https://www.telerik.com/blazor-ui/documentation/knowledge-base/scheduler-add-hyperlinks-in-appointments
Summary: Learn how to add clickable hyperlinks inside Telerik UI for Blazor Scheduler appointments by rendering anchor tags in the appointment template and binding them to a URL field.

Hello everyone,

Here are the highlights of the new online resources we published this week from 06 Oct 2025 to 13 Oct 2025:

Article: https://www.telerik.com/blogs/blazor-basics-using-local-storage-save-restore-form-input
Summary: You will use IJSRuntime to interact with browser localStorage, serialize your form model to JSON, and hook EditContext.OnFieldChanged and OnAfterRenderAsync to save and restore Blazor form input. The article walks through wiring an EditForm to persist changes as users type, repopulate values on first render (including Blazor Server after prerender), and clear storage on submit, with guidance on key management, debouncing, and avoiding sensitive data. Apply this to keep form state across reloads and navigation in Blazor WebAssembly and Server.

My pipeline is currently stuck due to this, I have a simple "dotnet install" in my pipeline that used to work and since the latest .NET SDK release (SDK 9.0.307) it started to fail with the following message:

• C:\Users\?????\.nuget\packages\telerik.licensing\1.4.10\build\Telerik.Licensing.targets(8,3): error MSB4216: Could not run the "ResolveTelerikProducts" task because MSBuild could not create or connect to a task host with runtime "NET" and architecture "x64". Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "C:\Program Files\dotnet\sdk\9.0.307\MSBuild.dll" exists and can be run.

I attempted to upgrade the Telerik.Licensing package manually to latest version but it didn't fix the issue.

We're starting a new internal project using Blazor (.NET 8/10) to build an in-house booking application.

Our UI/UX designs are already prepared in Figma, and we're now evaluating which Blazor component library would best support our implementation.

We are exploring component library which can easily be integrated with Figma design, save us re writing a component and reduce the development time.

• What was your experience like?

• How well did the components align with your design system (especially if using Figma)?

• Any performance, customization, or support issues?

• Would you recommend it for a booking-style application?

• Are free source component libraries better than enterprise paid libraries?

Thanks in advance for sharing your insights!

Given the documentation is useless, I've got to the point of logging in to the Telerik server and restoring the packages but I still get this error:

error MSB4216: Could not run the "ResolveTelerikProducts" task because MSBuild could not create or connect to a task host with runtime "NET" and architecture "x64". Please ensure that (1) the requested runtime and/or architecture are available on the machine

This is my yaml:

The documentation at the link below explaining how to prevent the user from having to clear cache when upgrading from one Telerik version to another has an issue with the css priority. My app targets .net 9 but I wasn't able to get the first solution using MapStaticAssets() to work so I implemented the second solution using cache busting. That resolved the caching error but it put the priority of all.css above any css I have in a style element in my component.

In my specific case I have a grid and I want the values in one of the columns to be links but using an anchor element in a grid doesn't underline and turn the content blue so I added css into my style tag in my component:

    .k-grid a {
        color: #0d6efd;
        text-decoration: underline;
    }

That works fine normally, but when I upgraded to the current version of Telerik and had cache issues and followed the cache busting instructions in the link, the content no longer looks like a link. See dev tools screenshots with and without cache busting.

https://www.telerik.com/blazor-ui/documentation/knowledge-base/common-browser-cache-buster

With cache busting it doesn't look like a link because all.css takes priority:

Without cache busting:

Any way to get around this?

I'm looking at ThemeBuilder Ultimate for use in my Blazor-Server UI project.  I went thru the 3 year old intro video but it's very out dated and seems to focus on Kendo UI.  There is no mention on how to get a ThemeBuilder project into an existing Blazor UI project?

Also, I assume ThemeBuilder Pro/Ultimate are separate subscriptions from my existing Blazor UI Complete subscription?  Your pricing material seems a bit confusing:

Why list Theme Builder ultimate under DevCraft Complete if it's not actually included in the DevCraft Complete subscription?

Theme builder looks to be a nice powerful and easy to use UI tool so I'd like more information before I make funding requests.

Hello,

Would it be possible to provide a clear set of steps—or ideally, a sample solution—demonstrating how to integrate Telerik Blazor with ASP.NET Identity using the .NET 9.0 framework? This seems like a fairly common requirement, but I haven’t been able to find any concise documentation that outlines the process.

I’ve created my project using the Blazor Web App template with Individual Accounts, and I’d like to confirm whether those settings are correct, and specifically, what additional steps are required to complete the integration such as changes to the Identity layout or pages (eg, Login.razor).

Thanks,
Kevin
