Your Monthly Fill of Telerik UI for ASP.NET Core - August 2019

It’s a high season for the Telerik UI for ASP.NET Core team, and we're working hard to enable our community of developers to create robust and impactful applications with professional UI. Check out what's new in our timeline, rating, grid and more.

As we get closer to the R3 2019 release in September, we want to share some insights and make sure you know what you will soon hold in your hands. All the components discussed here are not available yet, but will be part of our R3 2019 release – slated to come next month!

In this blog post we will try to give everyone an idea of what we’ve been grilling up over the last couple of months of the summer. Based on your feedback and technology trends, the Telerik UI for ASP.NET Core release will include new Timeline, Filter and Rating widgets. In addition to the new components, we are enhancing the Grid with a built-in Search Panel, and are working towards making Telerik Document Processing Library available for your ASP.NET Core applications!

New Components


For a more sophisticated, sleek and interactive way to visualize time events in your applications we are working towards releasing a new timeline widget.

The Timeline component will provide options for horizontal or vertical layout orientation, as well as visualization of the events time granularity (year, month, day), expanding and collapsing of the events, and intuitive customizations in terms of content, images, text, colors, and fonts.


The Rating widget will allow users to intuitively rate items in their applications, with multiple options to customize the rendering and behavior: rating scale (including handling avg. values), custom icons (stars, hearts, circles and more), single and continuous selection of items, keyboard navigation and accessibility.

The new Filter component will enable you to provide complex filtering expressions for data bound controls. The visual expression building will provide a user-friendly way to filter and locate data.

Document Processing

We are happy to announce that Telerik Document Processing will be soon added to our offering. Telerik Document Processing for ASP.NET Core is a set of UI-independent and cross-platform libraries that enables processing content between different formats, PDF file generation, and archive file management. It will include the following libraries:

  • PDFProcessing
  • ZipLibrary
  • SpreadStreamProcessing

Component Enhancements

Built-In Search Panel in Grid

Grids with large volumes of data require a straightforward way to search and locate records. That’s why in addition to the current grid filtering options, we are working towards adding a built-in search panel that enables users to easily search through the data and filter only relevant records in the Grid. The search panel will add a search text box inside the grid toolbar and will enable you to configure which grid fields will be searchable.

Telerik UI for ASP.NET Core is Preview 7 Compatible

All Telerik UI for ASP.NET Core components are compatible with the .NET Core 3.0 Preview 7 version, ensuring developers that are already looking at ASP.NET Core 3.0 can test our components in this preview version and prime us for the official release of ASP.NET Core 3.0.

As a leading provider for UI components we aim to be fully compatible shortly after the official ASP.NET Core version 3.0 release in September 2019, and along the way we will continue to provide preview compatibility on a regular basis.

In addition to all said, there are a few other interesting initiatives that we would like to share with you in one of our next blog posts, so stay tuned.
