Telerik UI for ASP.NET MVC Q2 2025

Unified Distribution for Trial and Commercial Packages

With the goal of streamlining user experience, the trial and commercial packages have been consolidated into a single unified distribution for Telerik UI for ASP.NET MVC. Access is now managed through a license key file, eliminating the need for separate trial download. For more information, please refer to Setting Up Your License Key.

Kendo.Mvc.Export

As of the Q2 2025 release, the Telerik.Core.Export package targets .NET Framework 4.6.2 in addition to .NET. You can the Telerik.Core.Export package in ASP.NET MVC5 applications, as well as in .NET applications. The old Kendo.Mvc.Export assembly will no longer be distributed.

Telerik.Zip

As of the Q2 2025 release, the following NuGet packages and assemblies no longer have a dependency to the Telerik.Zip library:

Telerik.Mvc.Export
Telerik.Web.Pdf
Telerik.Web.Spreadsheet

The Telerik.Zip library will continue to be shipped as a standalone library.

The responsive behavior of the Pager has been enhanced, which introduces the following changes:

The Pager's sizing is no longer based on breakpoints. Instead, the optimized responsive behavior renders as many elements as possible within the available space.
Input Type—When the Input() option of the Pager is enabled, the TextBox next to the navigation arrows is replaced with a NumericTextBox, and the numeric page number buttons are no longer rendered.
Page Selection—The page selection drop-down has been replaced with a NumericTextBox for improved user interaction.
NumbersSelectLabel() Property—The NumbersSelectLabel() option in the Messages() configuration has been removed as it is no longer needed with the replacement of the page selection drop-down.

These changes to the Pager affect all components that use a built-in pager, including the Grid, PDFViewer, and other data management components.
