21.1 Download — Devexpress

Many enterprises freeze their toolchain during critical development cycles. If your project was built on DevExpress 21.1, upgrading to a newer major version (e.g., 23.2 or 24.1) may introduce breaking changes or require extensive regression testing. Sticking with 21.1 ensures a stable environment.

While not officially supported, some developers succeed by using the DevExpress Visual Studio Extension from 21.1 and manually adding references. However, certain designers may crash. For VS 2022, consider upgrading to DevExpress 22.2+.

For high-density data applications, 21.1 introduces a new 'Compact' theme variation for WPF. This allows developers to display more information on the screen without overwhelming the user, a crucial requirement for financial trading platforms and logistics software. devexpress 21.1 download

Version 21.1 significantly expanded DevExpress's offering for Blazor, Microsoft's framework for building interactive web UIs with C#. This release introduced the Data Grid, Pivot Grid, and Chart components for Blazor, allowing developers to move away from JavaScript-heavy front ends and utilize C# for full-stack development.

Cause: DevExpress periodically removes old minor builds (e.g., 21.1.1 through 21.1.4) from the CDN, keeping only the final build (21.1.7).
Fix: Ensure you are selecting the latest build number. If the entire version is missing from the dropdown, contact DevExpress Support – they can manually grant access to archived builds for valid license holders.
